DTSC-50

DTSC-50 Digital Transfer Switch Controller for ATS

Woodward’s DTSC-50 digital transfer switch controller is an economical controller for open-transition (break before make) ATS (automatic transfer switch) control for emergency stand-by applications with a single generator. When the DTSC-50 detects a utility failure, it commands the generator to start and transfers the load to the emergency source. The DTSC-50 performs an open-transition re-transfer when utility power is restored, allowing the engine to cool down before stopping. It can be utilized in 1Ph2W, 1Ph3W, 3Ph3W, and 3Ph4W systems.
The DTSC-50 displays voltage and frequency values for each phase, as well as engine hours, maintenance hours, and number of transfers. Active alarms are annunciated via the seven segment LED display. Separate LEDs show breaker status and source availability. Sealed soft-keys enable the user to start the generator and operate the transfer switch manually.
