Products - Digital, Valve & Pump Driver

Standard open loop proportional driver:  Control dual or single proportional coils on pumps, directional control valves and other devices in an open loop (no feedback) configuration.  Coil current is controlled to match the input command signal.  Minimum current setting controls minimum speed or displacement and eliminates dead band.  Maximum current setting sets maximum speed or displacement.  Auto calibration provides maximum resolution from input device.  Can be operated with standard 10K potentiometer (included), or  analog signal such as from a joystick. Has fault monitoring for loss of command signal safety.

RPM Regulator Anti-Stall/HP Limiting Controller:  Adjusts its’ outputs as a function of the input RPM.  Anti-stall, or HP load limiting, progressively de-couples the load from the motor as RPM decreases to avoid stalling the engine. This method is typically used in situations where the operator controls the engine throttle and the load changes independently. The Anti-Stall action is used to prevent a sudden increase in load from causing the engine to stall before the operator has a chance to increase the throttle or decrease the load, or to automatically adjust the load without operator intervention.
