Key Functional Capabilities
The controller supports seamless power source transitions with configurable timing and logic, ensuring minimal disturbance to connected loads. Closed transition functionality allows temporary paralleling of sources for uninterrupted transfer, while synchronization checks prevent unsafe switching conditions.
The integrated FlexApp™ environment enables engineers to tailor control logic to site-specific requirements without external PLCs. Real-time status and configuration access via the DynamicsLCD™ interface simplify commissioning and diagnostics.
Typical Applications
The Woodward DTSC-200 is commonly deployed in installations where power continuity and transfer reliability are critical:
- Backup power systems for hospitals and healthcare facilities
- Data centers requiring uninterrupted power switching
- Industrial plants with dual power feeds
- Marine and offshore electrical systems
- Infrastructure with redundant generator or utility sources
