ETA-ECS3
Power Sequencer & Conditioner
REAR PANEL FEATURES
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.

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

and connect to Pin 2 to access the 12VDC.
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.
