ATS 115

Automatic Transfer Switch controller with 3 phase (RMS) mains voltage and 3 phase (RMS) generator voltage and current monitoring, suitable for operation with two different power sources.

ATS115/ATS115Plus is a device suitable to manage the switch in different plants configuration.

A or B sources can be set as “mains” or “genset” in any possible combination.
All the parameters can be set directly by the controller’s keyboard or, alternatively using the free software tool (BoardPRG3), available from SICES’ website.

ATS115, in both versions, has a graphic display that allows a real time check of the switch status, of measures and any occurred alarms.

ATS115 and ATS115Plus allows the remote control of the switch by its communication ports.
The Plus version, have an extensive input and output capability with optional communication interfaces.

  • True RMS measure for voltages of both sources, currents on loads.
  • Measure of active power and power factor.
  • Measure of frequency for both sources, powers on load.
  • 8 programmable digital inputs (insulated).
  • 8 programmable digital outputs.
  • USB Port and ETHERNET Port (for ATS115Plus).
  • Graphic display with single-line diagram representation.
  • Real time clock.
  • Events and data recording.
  • Remote switch commands and remote start and stop commands.
  • Embedded alarm horn.
