ECS-3
Power Sequencer & Conditioner
Introduction
Thank you for purchasing the Atlas Sound ECS-3 AC Power Sequencer and Conditioner. The ECS-3 has been designed to meet most
installation requirements for AC power distribution and equipment power protection. The 15A compact 1 RU 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 ECS-3 has incorporated a front panel pull-out dimmable LED tube light. The rear
of the rack can be illuminated by the optional Atlas Power 18" gooseneck LED lamp 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 ECS-3 provides a sequenced 12VDC output that can be used to trigger other devices such as the Atlas Sound ECM-20SH
20A stand alone AC power module.
The ECS-3 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, switching power supplies and lightning. 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
lightning 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 ECS-3 features Dual Clamping Suppression technology (DCS). If a spike
intrudes the AC system, the ECS-3 incoming AC Mains has special suppression circuitry to eliminate the unwanted energy and in the
unlikely event of any energy getting pass 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, and is 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 company 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 ECS-3 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 128VAC and 132VCA or 107VAC and 101VAC. This is to inform you that a surge
occurred and may have damaged voltage sensitive equipment. If an extreme voltage swing occurs above 132VAC or below 101VAC,
the ECS-3 Extreme Voltage Shutdown (EVS) protection circuit will automatically activate and turn all outlets off until it is manually reset.
The ECS-3 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 ECS-3 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 lightning strikes or 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 ECS-3 can be used:
• Restaurants
• Houses of Worship
• Schools
• Home Theaters
• Office Buildings
• Sports Bars

1. Unswitched AC Outlet – The two 120VAC outlets are always live when the ECS-3 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 ECS-3 and push the center button on the breaker.
3. System Activation Switch – To turn the ECS-3 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
settings.

6. AC Mains Function Display
7. AC Mains Voltage Display – This display will illuminate
when the AC Mains power cord is plugged into an AC
source. Note: the display has a 1.5% tolerance. Note: If the
voltage displayed is not between 107 - 128VAC, refer to the
troubleshooting section and item 12 below.
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 ECS-3 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 ECS-3.
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 ECS-3 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 ECS-3 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 ECS-3 due to high AC
Mains voltage. The ECS-3 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 ECS-3 due to
low AC Mains voltage. The ECS-3 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 ECS-3.
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 ECS-3 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 ECS-3 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 ECM-20SH. Contact Atlas Sound 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 or Off.
7. Unswitched AC Outlet – This 120VAC outlet is always live when the ECS-3 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 ECS-3 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 ECS-3 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.
10. DC Output – The ECS-3 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 ECM-20SH. This triggered 12VDC voltage
works in conjunction with Sequence 3 timing section. Contact Atlas Sound 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 ECS-3. The
ECS-3 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 ECS-3. Below are a few installation tips.
• After plugging the ECS-3 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 ECS-3 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
Issue: Wiring Fault LED is illuminated.
Possible Cause: AC Mains outlet is wired incorrectly.
Action Needed: Contact a certified electrician to inspect the building’s wiring.
Issue: No power to the AC outlets.
Possible Cause: Circuit breaker has tripped due to excessive load.
Action Needed: Remove one piece of equipment from the ECS-3, 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 turning
down that unit. If the ECS-3 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: The AC Mains Voltage exceeded 132VAC or the voltage dropped below 101VAC.
Action Needed: Measure the AC mains before the ECS-3. If the voltage is between 117VAC and 123VAC you may proceed to reset
the ECS-3 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 operation.
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: The AC Mains Voltage exceeded 128VAC or the voltage dropped below 107VAC
Action Needed: The ECS-3 must be re-sequenced to turn off the LED. Measure the AC mains before the ECS-3. If the voltage is
between 117VAC and 123VAC you may proceed to reset the ECS-3 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 operation.
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 ECS-3 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.

in other than a workman like 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 Atlas Sound 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 nonwarranty work is performed. In
the event of replacement or upon completion of repairs, return shipment will be made with the transportation charges collect.
