ETA-20SH
AC Power Conditioning & Suppression Module
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-

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.

APPLICATIONS
The ETA-20SH is designed to be flexible for use in a variety of applications. When used with a sequenced controller it allows the
turning of equipment on and off from a remote location to save energy and to reduce an in-rush of current that stresses the main AC
line. It also can be used as a standalone unit for protection against voltage surges and applies EMI/RFI filtering to clean up the AC
power at the load source. The following are just a few examples of applications in which the ETA-20SH can be used:
