Core Functions

1. High‑precision phase, frequency and voltage matching for genset parallel operation with mains or other generators.

2. Automatic speed trim output (4‑20 mA / pulse signal) to adjust engine governor for frequency synchronization.

3. Automatic voltage matching control; configurable sync window, slip frequency and phase angle threshold.

4. Built‑in anti‑parallax protection, reverse‑power interlock and breaker failure detection functions.

5. Front‑panel digital display and key operation; Modbus‑RTU communication for remote monitoring and parameter configuration.

6. DIN‑rail/panel‑mount compatible design, plug‑and‑play integration with Woodward easYgen and 2301 series governors.
