ETA-S20RT
AC Distribution & Suppressor Unit
INTRODUCTION
Thank you for purchasing the ETA Systems ETA-S20RT AC Distribution and Suppressor Unit. The ETA-S20RT has been designed to
meet most installation requirements for AC power distribution and equipment power protection. To light your rack, the ETA-S20RT

contact closure. With the closure of the remote activation switch, 12VDC at 100mA is available to power a remote status LED.
An Emergency Power Down function, or EPD, can also be created by using the Remote Activation feature by simply keeping the
Remote Activation contact closed until a condition occurs that requires a system shut down. When the contacts are opened, it will
remove power from the switched outlets to protect equipment. A rear mounted bypass switch disables the Remote Activation should
the need arise.
The ETA-S20RT features noise filtering for unwanted Radio Frequency Interference (RFI) that is commonly introduced into AC lines by
nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise and Electromagnetic Interference (EMI)
from such items as electric motors and external 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. 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. The ETA-S20RT’s circuitry is very fast and can suppress unwanted energy within a nanosecond response
and sustain the suppression up to 2 milliseconds, thus ensuring virtually trouble-free protection. If damage to the suppression circuitry
occurs, the AC fault LED will illuminate.
The ETA-S20RT incorporates EVS (Extreme Voltage Shutdown) to remove AC power from devices plugged into the switched outlets in
the event of unsafe high or low voltage conditions. A convenient front panel LED indicates if shutdown has occurred.
The ETA-S20RT offers power management control, noise filtering, and over/under voltage and spike/surge protection to make it one of
the most compact, effective power management protection systems on the market today.
