Woodward’s 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.

    Feature overview:

    • Configurable for open, delayed, and closed transition transfer
    • Configurable for Utility-to-Gen, Generator-to-Generator, and Utility-to-Utility applications
    • Closed transition transfers can be accomplished in times < 100ms
    • In-phase monitoring (sync-check)
    • Load/no load test functionality
    • Engine exerciser (load/no load test) routine with fully adjustable interval
    • Peak shaving mode
    • Load shedding
    • Extended parallel time (for closed transition transfers that take longer than 100ms)
    • Transfer and/or re-transfer inhibit
    • Source priority selection
    • Elevator pre-transfer and motor load disconnect timers
    • Event/Alarm log system with real time clock
    • Internal breaker interlock utilizing discrete inputs for breaker position detection
    • Freely configurable discrete I/O with support for external I/O expansion units (e.g. Woodward IKD 1)
    • RS-232, RS-485 and CAN bus interfaces for remote control and visualization purposes
    • Supports CANopen and Modbus RTU protocols
    • PC and/or front display configuration
    • 128x64 pixels graphic LCD display
    • LogicsManager provides programmable logic functions that eliminate relay logic or PLC`s
    • True RMS voltage, current and power sensing
    • LEDs for source availability and breaker status
