Key Features

• Dual control modes: Isochronous (zero droop) for standalone constant-speed operation; droop control for grid parallel and load sharing.

• High accuracy: Speed regulation ±0.25% with adaptive PID tuning; supports 0.5–32,000 Hz speed input.

• Flexible I/O: 2 speed inputs (MPU/proximity), 8 analog (4–20 mA), 20 discrete inputs; 2 actuator outputs (4–20 mA/20–200 mA), 8 relay outputs.

• Integrated protection: Overspeed trip, critical speed avoidance, soft start, valve position limiting, first‑out fault logging.

• Communications: RS‑232/RS‑485 (Modbus RTU/ASCII); multi‑protocol support for remote monitoring.

• Rugged design: MIL‑STD‑810G compliance; operates –40 °C to +85 °C; IP20 enclosure; CE/UL certified.
