DTSC-200 for ATS Controller

Woodward’s DTSC-200 is the ultimate control for new ATS (automatic transfer switch) builds and retrofits. A complete measurement and protection package, it easily configures to Utility-to-Generator, Generator-to-Generator, or Utility-to-Utility systems for open, delayed, or closed-transition transfer with synch-check to ensure the smoothest possible transfer.
High-end features like transfer inhibit, source priority selection, load shed, motor load disconnect, elevator pre-signal, and engine exerciser timers come standard in this incredibly versatile, cost-effective control.



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.
