ETA-ECS3
Power Sequencer & Conditioner
INTRODUCTION
Thank you for purchasing the ETA Systems ETA-ECS3 AC Power Sequencer and Conditioner. The ETA-ECS3 has been designed to
meet most installation requirements for AC power distribution and equipment power protection. The 15A compact 1RU unit features
three sequential timing sections that can be activated via the unit, or remotely. Front panel activation is via a momentary switch, while
rear activation is via a momentary contact closure, or by 5-24VDC trigger feed. AC Mains Voltage can be monitored via the front panel
from the precision Digital Volt Meter. To light your rack, the ETA-ECS3 has incorporated a front panel pull-out dimmable LED tube light.
The rear of the rack can be illuminated by the optional Atlas Power 16" gooseneck LED lamp, AP-GNL18, connected via an XLR style
socket. LED lamps are far superior in longevity along with heat reduction when compared to traditional incandescent lamps and the
XLR base mounts are also superior to the commonly used BNC type base. If a 15A AC Mains power source is not enough to meet the
amperage demand of your system, the ETA-ECS3 provides a sequenced 12VDC output that can be used to trigger other devices such
as the ETA Systems ETA-20SH 20A stand alone AC power module.
The ETA-ECS3 also features noise filtering for unwanted Radio Frequency Interference (RFI) that are commonly introduced into the AC
lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise from Electromagnetic Interference
(EMI) from such items as electric motors and switching power supplies. The benefit of these filters can be seen on video products or
audibly by reducing static pops and external signal interference.
Unstable AC Mains voltage is one of the main reasons for equipment failure. AC Spikes, or Transients, are commonly caused by light-
ning storms or utility power plant grid switchovers. The amount of energy that can be injected into the power system can be immense
with voltages reaching 6kV or amperage peaks of 3000A. These spikes are very fast and usually only last for a very short period of
time. To protect against this potential problem, the ETA-ECS3 features Dual Clamping Suppression technology (DCS). If a spike intrudes
the AC system, the ETA-ECS3 incoming AC Mains has special suppression circuitry to eliminate the unwanted energy and in the
unlikely event of any energy getting passed the first stage, each sequenced output section has redundant DCS circuitry clamping the
unwanted energy. This circuitry is very fast and can suppress unwanted energy within a nanosecond, while sustaining the suppression
up to 2 milliseconds, thus ensuring virtually trouble free protection.
High and low AC Main line voltages are another major contributor to equipment failures. High line can also be known as surges.
Surges usually are a slower steady state rise in voltages ranging from 128VAC and up. They can be caused from fluctuations from the
utility company’s power lines or industrial equipment turning on and off on the same power leg of the building’s incoming AC. Low line
is also known as brownouts. This happens when the AC Mains drops below 107VAC. Most of the time it is caused by the utility com-
pany not being able to supply enough power during heavy utility consumption time periods, such as heat waves. Another factor would
be from voltage drops in AC lines due to long transmissions. The ETA-ECS3 will not only inform you if one of these conditions occurs,
but under extreme variances in the AC Mains, it will shut the power to the equipment off. The Abnormal Voltage indicator on the front
panel will flash if the AC Mains is between 101VAC and 107VCA or 128VAC and 132VAC. This is to inform you that a surge occurred
and may have damaged voltage sensitive equipment. If an extreme voltage swing occurs below 101VAC or above 132VAC, the
ETA-ECS3 Extreme Voltage Shutdown (EVS) protection circuit will automatically activate and turn all outlets off until it is manually reset.
The ETA-ECS3 offers sequenced power management control, along with noise filtering and spike/surge protection making it the most
compact, effective power management protection system on the market today.

APPLICATIONS
The ETA-ECS3 was designed to be flexible with features that allow it to be used in a variety of applications. The sequenced outputs
allow the turning of equipment on and off in a particular order, to eliminate an in rush of current and audible pops that often occur with
non-sequenced power strips. It also can be used solely for protection against voltage surges. If fuzzy video or frequent static pops
occur, the AC power conditioning will eliminate or reduce those inconveniences. The following are just a few examples of applications
the ETA-ECS3 can be used:
•

1. Unswitched AC Outlet – The two 120VAC outlets are always live when the ETA-ECS3 power cord is plugged into an AC mains
power source and voltage is present. If voltage is present at the outlets, it will be displayed on the AC Mains Meter. Note: The AC
mains power switch or sequencer section does not affect the Unswitched AC Outlets. The Unswitched Outlets are protected by
the surge protection circuitry, but will not be shut off by the EVS circuit.
2. AC Mains Breaker – The 15A rated breaker will open if the combined continuous current draw of all AC outlets exceeds 15A.
Note: In audio applications, peak current demands commonly exceed the continuous current ratings on AC outlets. Note: The
breakers are designed to exceed their rating for a short period of time. If the breaker is tripped, to reset you must first remove the
load from the ETA-ECS3 and push the center button on the breaker.
3. System Activation Switch – To turn the ETA-ECS3 On or Off, press the momentary switch once.
4. Pull Out Light – The LED light is designed to be pulled out when needed.
5. Pull Out Light Dimmer Switch – The Pull Out Light can be turned “On” or “Off” by this switch. There are also two brightness

8. Sequence Indicator – There are three green LED
active sequence outlet indicators labeled “SEQ 1”,
“SEQ 2”, and “SEQ 3”. Their sequence timing is set
for 3 seconds between Sequence 1-2 & 2-3 while in “On”
mode, and Sequence 3-2 & 2-1 during “Off”
mode. When the LED is illuminated, the corresponding AC
outlet on the rear of the chassis will be active or “Live”.
Turned “On”, the order the trigger sequence is “SEQ 1, SEQ
2, SEQ 3”. Turned “Off”, it is “SEQ 3, SEQ 2, SEQ 1”.
9. AC Mains Wiring Polarity Fault Indicator – The Red LED

will illuminate if the AC Mains Power Cord is plugged into an
AC Mains outlet that is wired incorrectly, such as when the AC Hot and the AC Neutral are wired backwards.
10. AC Mains Breaker Indicator – This Red LED will illuminate if the maximum unit current draw is exceeded. The breaker rating is
15A, but will handle higher peaks for a short period of time. The LED will illuminate until the AC Mains Breaker is reset.
11. AC Fault Indicator – Although the Dual Clamping Suppression (DCS) circuit virtually assures protection from most transient
voltage spikes and surges nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device
to absorb without some degree of damage. In the rare instance that this occurs and the DCS circuit has been damaged, the Red
“AC Fault” LED indicator will illuminate and an internal buzzer will sound. The ETA-ECS3 will also shut off permanently until the
unit is repaired. Note: If the AC Fault LED is illuminating it is important to have all equipment that was connected to that AC
Mains Line inspected for proper operation.
12. AC Mains Abnormal Voltage Indicator – This LED flashes under several AC Mains fault situations that are listed below. Normal
operating voltages for AC Mains voltage is considered to be between 108VAC and 125VAC. Any voltages exceeding those
parameters are considered a risk to damage equipment plugged into the ETA-ECS3.
High AC Line Mains – The Abnormal Voltage LED will flash between 128VAC – 132VAC indicating possible damage may occur
to equipment due to high AC Mains voltage. The ETA-ECS3 outlets will remain active but the LED will stay flashing even if the
voltage returns to a normal operating range. To stop the LED from flashing the system activation switch must be cycled “Off”.
Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
Low AC Line Mains – The Abnormal Voltage LED will flash between 101VAC – 107VAC indicating possible damage may occur
to equipment due to low AC Mains voltage. The ETA-ECS3 outlets will remain active but the LED will stay flashing even if the
voltage returns to a normal operating range. To stop the LED from flashing the System Activation Switch must be cycled “Off”.
Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
Extreme High AC Line Mains – If the AC Mains reach 132VAC, the EVS (Extreme Voltage Shutdown) circuit will be triggered to
shut off the AC outlets while activating the Abnormal Voltage LED. The Red LED will illuminate steady and the AC Mains Voltage
Meter will flash OL (Overload), indicating possible damage may occur to the equipment plugged into the ETA-ECS3 due to high
AC Mains voltage. The ETA-ECS3 outlets will remain off until the System Activation Switch is cycled “Off”.
Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
Extreme Low AC Line Mains – If the AC Mains lowers to 100VAC, the EVS (Extreme Voltage Shutdown) circuit will be triggered
to shut off the AC outlets while activating the Abnormal Voltage LED. The Red LED will illuminate steady and the AC Mains
Voltage Meter will flash OL (Overload), indicating possible damage may occur to the equipment plugged into the
ETA-ECS3 due to low AC Mains voltage. The ETA-ECS3 outlets will remain off until the System Activation Switch is cycled “Off”.
Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.

1. AC Mains Input – Connect the 9’ (3m) power cord to a 15A 120VAC outlet to provide power to the ETA-ECS3.
2. Sequence 1 AC Outlets – The three AC outlets are “Live” when the Sequence 1 section is activated. These outlets are
recommended for products such as Computers, Modems, Routers, DSP Processors, Cable/SAT, DVD, or CRT TV’s. These outlets
have a special filter circuit that is optimized to reduce interference to your Digital and Analog components. The total maximum
continuous draw for this sequential section is 10A and the total current draw for the ETA-ECS3 is 15A. Note: It does not harm
high current audio components to be connected to the Sequential Section 1 digital filter outlets.
3. Sequence 2 AC Outlets – The two AC outlets are “Live” when the Sequence 2 section is activated. These outlets are
recommended for Analog and Digital type products such as Audio Receivers, Tape Decks, Mixers, or Video Equipment. These
outlets have a special filter circuit that is optimized to reduce interference to your analog type components. The total maximum
continuous draw for this sequential section is 10A and the total current draw for the ETA-ECS3 is 15A. Note: It does not harm
high current audio components to be connected to the Sequential Section 2 filter outlets.
4. Sequence 3 AC Outlet – The single high current non filtered AC outlet is “Live” when Sequence 3 section is activated. This
15A NEMA outlet is designed to deliver a maximum 12A continuous current to power hungry components like amplifiers and
projectors. In audio applications, peak current demands commonly exceed the continuous current ratings on AC outlets. The unit
is protected by the internal AC Mains 15A breaker if excessive continuous current is drawn from the unit. It does not harm low
power consuming components when connected to the Sequential Section 3 Analog filter outlets. If more high power outlets
are needed or if 15A is not enough current to support your power requirements you can use the 24VDC trigger to activate an
additional power outlet such as the ETA-20SH. Contact ETA Systems for AC outlet options.
5. XLR Light Socket – A 12VDC XLR light socket is to provide power for the optional Atlas Power AP-GNL18 light.
6. Light Socket Power Switch – This switch turns the XLR light socket ON / OFF.
7. Unswitched AC Outlet – This 120VAC outlet is always live when the ETA-ECS3 power cord is plugged into an AC Mains power
source and voltage is present. If voltage is present at the outlets it will be displayed on the AC Mains Meter. Note: The AC Mains
power switch or sequencer section does not affect the Unswitched AC Outlets. The Unswitched Outlets are protected by the
surge protection circuitry but will not be shut off by the EVS circuit.
8
External Voltage Sequence Trigger – The ETA-ECS3 can be activated remotely by
providing DC voltages between 5VDC and 24VDC. Note: This function overrides the front
panel System Activation Switch.
9. External Sequence Trigger – The ETA-ECS3 can be activated remotely by placing a
Momentary Switch between the two contact points. This function is in parallel with the front
panel System Activation Switch. Note: If remote activation requires a remote Hard Switch
Contact Closure (CC), we suggest using the 12VDC from the rear XLR light port, running
through a remote switch and return the DC Voltage to Remote V Input Pin to activate the
unit. When the rear light switch is in the ON position, 12VDC is always present in Pin 2
regardless if the ECS-3 is activated. It will be required to use a standard XLR male connector
and connect to Pin 2 to access the 12VDC.
8

10
10. DC Output – The ETA-ECS3 can handle 15A of current before the breaker opens. If 15A is not enough current to support the
power requirements, this output can be used to activate an additional power outlet such as the ETA-20SH. This triggered 12VDC
voltage works in conjunction with Sequence 3 timing section. Contact ETA Systems for AC outlet options. Note: This DC output
can also be used to power an LED indicator for a remote activation switch such as the Atlas ECS-KSW3.

INSTALLATION
Before installing we strongly suggest you read the entire manual to ensure you benefit from all the features of the ETA-ECS3. The
ETA-ECS3 can be placed on a shelf or rack mounted in a standard 19" width rack. Placement within a rack is not critical but the rack
should be within 6' of dedicated 15A AC outlet. Always make sure the 15A outlet is properly inspected by a certified electrician prior to
connecting the ETA-ECS3. Below are a few installation tips.
•
•
•
After plugging the ETA-ECS3 into a 15A AC Mains outlet inspect the Wiring Fault LED for illumination. The LED should not be on.
Inspect the equipment that is to be plugged into the ETA-ECS3 to ensure it does not exceed 15A total amperage draw.
Divide the equipment into three categories. Pick the outlets that match the outlets equipment use.
TROUBLESHOOTING GUIDE
Issue:
Wiring Fault LED is illuminated.
Possible Cause:
Action Needed:
AC Mains outlet is wired incorrectly.
Contact a certified electrician to inspect the building's wiring.
Issue:
No power to the AC outlets.
Possible Cause:
Action Needed:
Circuit breaker has tripped due to excessive load.
Remove one piece of equipment from the ETA-ECS3, and push the breaker re-set tab located on the front panel.
Note: We suggest first locating the highest power-consumer such as a power amplifier and disconnecting or turn-
ing down that unit. If the ETA-ECS3 breaker continues to trip, relocating some of the gear may be required.
Issue:
No power to the AC outlets, “Abnormal Voltage” indicator is illuminated, the Volt Meter is Flashing and you hear a
buzzer from the unit.
Possible Cause:
Action Needed:
The AC Mains Voltage exceeded 132VAC or the voltage dropped below 101VAC.
Measure the AC mains before the ETA-ECS3. If the voltage is between 117VAC and 123VAC you may proceed to
reset the ETA-ECS3 by restarting the start up sequence.
Note: It is important to have all equipment that was connected to that AC Mains Line inspected for proper opera-
tion. If the problem persists, contact your local power company for the cause of unstable AC line conditions.
Issue:
Abnormal LED Flashing when you have power to all outlets.
Possible Cause:
Action Needed:
The AC Mains Voltage exceeded 128VAC or the voltage dropped below 107VAC
The ETA-ECS3 must be re-sequenced to turn off the LED. Measure the AC mains before the ETA-ECS3. If the volt-
age is between 117VAC and 123VAC you may proceed to reset the ETA-ECS3 by restarting the start up sequence.
Note: It is important to have all equipment that was connected to that AC Mains Line inspected for proper opera-
tion. If the problem persists, contact your local power company for the cause of unstable AC line conditions.
Issue:
AC Fault LED is Flashing, a buzzer is sounding and you have no power at any outlets.
Possible Cause:
Although the Dual Clamping Suppression (DCS) circuit virtually assures protection from most transient voltage
spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any
device to absorb without some degree of damage. In the rare instance that this occurs, the DCS circuit has been
damaged during the suppression.
Action Needed:
If this happens, the ETA-ECS3 will shut off and the unit will need to be repaired or replaced. It is important to have
all equipment that was connected to that AC Mains Line inspected for proper operation.

LIMITED WARRANTY
All products manufactured by ETA Systems are warranted to the original dealer/installer, industrial or commercial purchaser to be
free from defects in material and workmanship and to be in compliance with our published specifications, if any. This warranty
shall extend from the date of purchase for a period of one year. Additionally, fuses and lamps carry no warranty. ETA Systems will
solely at its discretion, replace at no charge or repair free of charge defective parts or products when the product has been applied
and used in accordance with our published operation and installation instructions. We will not be responsible for defects caused by
improper storage, misuse (including failure to provide reasonable and necessary maintenance), accident, abnormal atmospheres, water
immersion, lightning discharge, or malfunctions when products have been modified or operated in excess of rated power, altered,
serviced or installed in other than a workmanlike manner. The original sales invoice should be retained as evidence of purchase under
the terms of this warranty. All warranty returns must comply with our returns policy set forth below. When products returned to ETA
Systems do not qualify for repair or replacement under our warranty, repairs may be performed at prevailing costs for material and labor
unless there is included with the returned product(s) a written request for an estimate of repair costs before any non-warranty work is
performed. In the event of replacement or upon completion of repairs, return shipment will be made with the transportation charges
collect.
EXCEPT TO THE EXTENT THAT APPLICABLE LAW PREVENTS THE LIMITATION OF CONSEQUENTIAL DAMAGES FOR PERSONAL
INJURY, ETA SYSTEMS SHALL NOT BE LIABLE IN TORT OR CONTRACT FOR ANY DIRECT, CONSEQUENTIAL OR INCIDENTAL
LOSS OR DAMAGE ARISING OUT OF THE INSTALLATION, USE OR INABILITY TO USE THE PRODUCTS. THE ABOVE WARRANTY IS
IN LIEU OF ALL OTHER WARRANTIES INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE.
ETA Systems does not assume, nor does it authorize any other person to assume or extend on its behalf, any other warranty,
obligation, or liability. This warranty gives you specific legal rights and you may have other rights which vary from state to state.
