Dual Gensets Automatic Transfer Switch Controller

ATS-33

Automatic Transfer Switch Controller for Dual Gensets

ATS-33 controller is specially design for dual generators power system where location is without utility power. The primary generator is backed up by a secondary standby generator incase of primary start up failure or when load power is lost from the primary generator the controller will start up the secondary generator and automatically transfer load to the standby power. Or the ATS-33 can program the dual generators to operate in a timely relay duty operation. The controller is equipped with optional USB, RS485, and Ethernet remote communication expansion slot, allowing user to purchase preferred optional communication module for alternative remote monitoring and operation.
