Generator Governor Automatic Control Speed Controller ESD5221Diesel Generator Speed Controller ESD5221 Speed Control Unit is rugged enough to be placed in a control cabinet or engine mounted encosure 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.
ESD5221 built on the basis of the start of the new fuel control and smooth slow start to control the process, these new features can be resolved in the engine to start the process by the rapid filling of black smoke caused by the phenomenon has greatly improved the engine's life . At present,it is very rich, perfect models in the new generators are widely in use.
