Diesel Generator Speed governor Speed Control Unit ESD5522E

Generator Frequency Control Electronic Speed Controller ESD5522E is rugged enough to be placed in a control cabinet or engine mounted enclosure with other dedicated control equipment. If water, mist or condensation may come in contact with controller, it should be mounted certically. This will allow the fluid to drain away from the speed control unit.

The ESD speed control is compatible with proportional Actuators except the ACB2001 electric actuator since this high torque actuator also requires current limiting. Ruggedly built to withstand all engine environments, the ESD’s STARTING FUEL and SPEED RAMP features will minimize engine exhaust smoke experienced prior to attaining engine operating speed and smooth out response.
