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.
