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.
