Key Features
– Dual Control Modes: Isochronous (zero-droop) for constant speed and droop for load sharing in parallel operation.
– Precise Load Sharing: Maintains ±5% load balance among multiple generators with matched speed settings .
– Wide Speed Range: Configurable for low to high-speed prime movers (500–12000 Hz) .
– Flexible I/O: Accepts analog (4–20 mA/1–5 VDC) and discrete inputs; drives hydraulic/electric actuators.
– Robust Protection: Detects speed sensor failure, overspeed, and load faults with configurable alarm/trip outputs.
– Industrial Durability: Metal enclosure, wide temperature tolerance, and vibration/shock resistance for harsh environments .
– Easy Configuration: Front-panel potentiometers for speed, gain, and droop adjustments; compatible with Woodward SPM-A synchronizer
