Sigmadrive Series Motor Controllers

Sigmadrive series motor controllers are available in traction, pump, and an innovative dual pump and power steer assist variants. Sigmadrive series controllers offer excellent continuous current ratings and comprehensive protection from all overcurrent fault conditions due to the high-resolution current measurement. Sigmadrive series controllers also offer protected contactor drivers with inbuilt coil suppression. The dual pump models offer a high-power output for the main lift pump, and a secondary output for the smaller power steering assist pump.
