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 paralleling via discrete input. “Custom” features like transfer inhibit, source selection, load shed/restore, elevator pre-signal and engine test programs come standard.
Logics Manager TM - Programmable Boolean logic functions along with ample, expandable discrete I/O allows for complex transfer schemes without using external relay logic or a separate PLC!
FlexApp TM - Easily configures the DTSC-200 for:
Utility-to-Generator Utility is preferred with a generator as the emergency source
Generator-to-Generator One genset is preferred with a second genset as backup
Utility-to-Utility Utility is preferred with second utility as the emergency source
Dynamics LCDTM - The graphic LCD interface with sealed soft-keys displays source voltage, frequency, phase rotation, current, real/reactive power, I/O status and alarms. Maintenance calls and event history (300 FIFO entries with real time clock and 6 year battery) are easily viewed and are password protected. A line diagram with four high-intensity LEDs clearly dis-plays source availability and breaker closed status. The galvanically-isolated CAN open port permits connection of up to (2) Woodward IKD1 modules, providing as much as 16 additional discrete inputs and outputs. RS-485 Modbus RTU Slave full-duplex communication allows for remote annunciation
