ECS-204

20A Power Conditioner & Sequencer

Introduction

Thank you for purchasing the Atlas Sound ECS-204 AC Power Sequencer and Conditioner. The ECS-204 has been designed to meet

most installation requirements for AC power distribution and equipment power protection. The 20A compact 1 RU unit features four

internal sequential timing sections, three on the unit and one to trigger an external device. All can be activated via the unit locally or

remotely. Front panel activation is via a momentary switch, while rear activation can be accomplished via a remote momentary switch,

latching switch, or by 5-24VDC. AC Mains Voltage can be monitored via the front panel from the precision Digital Volt Meter. The ECS-

204 has incorporated dual front panel USB charge ports that can be used to charge devices such as cell phones or music players. To

light the rack this charge port also supports an optional USB gooseneck lamp. The rear of the rack can be illuminated by the optional

Atlas Power 16" gooseneck LED lamp (AP-GNL) connected via an XLR style socket.

If a 20A AC Mains power source is not enough to meet the amperage demand of your system, the ECS-204 provides a sequenced

12VDC or contact closure output (Seq 4) that can be used to trigger other devices such as the Atlas Sound ECM-20SH 20A standalone

AC power module. Also, up to 3 ECS-204 can be linked together to give you 12 sequenced outputs. Sequence timing selection is made

by a rear panel switch selection. There are four choices that range from 3 seconds to 2 minutes.

The ECS-204 incorporates an Emergency Power Down (EPD) feature. The EPD may be required by the local fire code to pass site

inspection. This port when activated turns Off all channels at once. 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-204 features Dual Clamping Suppression technology (DCS). If a spike intrudes the AC system, the ECS-204 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.

The ECS-204 also features noise filtering for unwanted Radio Frequency Interference (RFI) that is 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 items such as electric motors, switching power supplies and lightning. The benefit of these filters can be seen on video

products or audibly by reduced static pops and external signal interference.

High and low AC Main line voltages are another major contributor to equipment failures. High line is also known as surges. Surges

usually are a slower steady state rise in voltages ranging from 128VAC and up. They can be caused by fluctuations in 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-204 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-204 Extreme Voltage Shutdown (EVS) protection circuit will automatically activate and turn all outlets Off until it is manually

reset or the voltage is stable.

The ECS-204 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-204 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-204 can be used:

• Restaurants

• Houses of Worship

• Schools

• Home Theaters

• Office Buildings

• Sports Bars
