Product Description
Woodward DTSC-200 Digital Transfer Switch Controller
Product Overview
- The Woodward DTSC-200 is a Digital Transfer Switch Controller designed for automatic control and monitoring of transfer switches in power management systems, such as emergency backup power, industrial power plants, and critical infrastructure applications. This microprocessor-based controller manages the seamless transition between primary (utility) and secondary (generator) power sources, ensuring reliable power supply continuity. The DTSC-200 supports open, closed, and delayed transition transfer modes, making it suitable for a variety of transfer switch configurations. It features a user-friendly interface with a graphical display and robust communication options for integration into complex power systems. Compared to Woodward’s genset controllers (e.g., EasyGen-3500-5, 8440-2087) or excitation systems (e.g., DECS-100-B15), the DTSC-200 focuses specifically on transfer switch control, not engine or generator management. It is distinct from Woodward’s electronic governors (e.g., 8406-121), actuators (e.g., 8408-921), and other modules (e.g., 5466-1510 CPU).
