INTRODUCTION
The ETA Systems ETA-20SH is a 120V 60Hz AC Electrical Control Module (ECM), 20A Single Housing (SH) Power Conditioner and AC
Spike Suppressor that is designed to be used as a standalone unit or in conjunction with an ETA Systems Sequence controller ETA-
ECS6RM or the ETA-ECS3 up to 1000' away.
The ETA-20SH features noise filtering for removing unwanted Radio Frequency Interference (RFI) and EMI filters to reduce noise from
Electromagnetic Interference (EMI) caused by items such as electric motors or switching power supplies. The benefit of these filters
can be seen on video products or audibly by reducing static pops and external signal interference. If an AC spike or surge appears,
the ETA-20SH also incorporates Clamping Suppression technology to prevent the unwanted energy from getting into your AV system.
Other features include a Manual Bypass Switch, Incoming AC presence LED, Active LED and an AC Fault indicator. When interfaced
with the ETA-ECS6RM Sequencer controller, Extreme Voltage Shutdown (EVS) Circuitry is active, along with Voltage and Current status
readings.
