ESD5520E Electronic Speed Control Generator Governor


ESD5520E Electronic Speed Control Description

Generator Governor Control Unit Speed Controller ESD5520E 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 the controller, it should be mounted vertically. This will allow the fluid to drain away from the speed control unit.

Speed Controller ESD5520E based on 5111, newly added starting fuel quantity control and smooth and slow starting process control are added. These new features can solve the black smoke phenomenon caused by rapid refueling during the start of the engine, which greatly improves engine life. It is a very rich and perfect model at present and is widely used in new generators.

(ESD5520E is a governor designed for supporting Cumming EFC actuators.)
