ESD5111 Series | Speed Controls


  • This is the best way of governing a generator where strict control of engine speed is desired irrespective of engine load. As the load is added and removed, the governor maintains a constant engine speed, stabilizing the load.
  • The speed control units are application based and can be used with any of GAC’s actuators. Actuator types: throttle body, pump mount, motor mount, and / or universal.
  • Save energy costs by regulating motor speed according to load requirements. Control a wide variety of engines in an isocrat or fall mode. It is designed for high reliability and ruggedly built to withstand the engine environment. Accessory inputs for variable speed load sharing operation available.
  • Application in: military grade equipment, rail, marine, industrial, heavy machinery, gaseous engines, power generation, oil and gas and much more GAC is ISO 9001 certified | We carry the full line of Governors America Corp products, email Thunder Parts your requirements!
  • An electronic speed control system consists of four main components: steering wheel, magnetic speed pad, speed controller, and an actuator. The speed controller compares the desired speed with the speed measured from the magnetic speed pad.
