The extremely flexible DTSC-200 controller is easily con-figured for a wide range of automatic transfer switch applications including Main-Gen, Gen-Gen or Main-Main systems using circuit breakers or latching contactors. Source transfer can be performed as open, delayed or closed transition with in-phase monitoring (synch check) that can be enabled for all transition types to ensure smooth transfer. The closed transition overlap time can be limited to less than 100 ms for momentary, make-before-break transfers, or extended indefinitely for paral-leling via discrete input. “Custom” features like transfer inhibit, source selection, load shed/restore, elevator pre-signal and engine test programs come standard.
