The ESD5330 speed control unit is rugged enough to be placed in a control cabinet or engine mounted enclosure with other dedicated control equipment. The circuit board is conformally coated to seal out moisture and resist vibration. If water, mist or condensation can come in contact with the controller, it should be mounted vertically. This will allow any accumulated fluids to drain away from the speed control unit.


The ESD5330 Series his several special built in features:

  • A Two Element Speed Switch (overspeed sensing and crank termination)
  • Speed Ramping from Idle to Operating Speed
  • Starting Fuel Control for lower engine exhaust emissions
  • A unique actuator power drive circuit
