AC Power Conditioning & Suppression Module, 2 Outlets, 20A


The ETA-20SH is a single housing unit for 20A lines. Features 2 outlets that support AC spike and surge suppression, AC mains voltage monitoring, EVS circuitry, and remote activation. It also supports current monitoring and EMI/RFI filtering for applications where they are used individually.


  • 2 Outlets, 20A
  • RFI/EMI noise filtering
  • Spike & Surge suppression, DCS circuitry
  • Extreme Voltage Shutdown (EVS) below 101V or above 132V AC line
  • AC Fault indicator
  • Fuse protection @ 20A slow blow
  • Manual bypass switch
  • Incoming AC presence LED
  • Active outlet LED
  • Status signals output for voltage and current

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:

  • Restaurants
  • Houses of Worship
  • Schools
  • Home Theaters
  • Office Buildings
