The ESD2200 governor unit is an all- electronic device designed to control engine speed with fast and precise response to transient load changes.

GAC ESD2200 electronic governor

The GAC ESD2200 electronic governor offer fast response to transient load changes

This closed loop governor, when connected to a electronic throttle actuator and supplied with a magnetic pickup sensor signal, will control a wide variety of engines in isochronous mode. It is designed for high reliability and is also hard potted to withstand the engine environment.

Main features also include:

  • 12 or 14 VDC.
  • Isochronous Operation.
  • Adjustable PID Function.
  • Light Force Option Available.
  • 8:1 Speed Range Control.

Simplicity of installation and adjustment was foremost in the design of this controller. Non-interacting performance controls allow near optimum response to be easily obtained.

Other features include protection against reverse battery voltage, transient voltages, accidental short circuit of the actuator, and fail safe design in the event of loss of speed sensor signal or battery supply.


Will the GAC ESD2200 governor fit my brand of engine?

The ESD2200 electronic governor is compatible with all GAC electronic throttle actuators and is suitable for a wide range of engine brands:

  • Perkins.
  • Yanmar.
  • Kubota.
  • Isuzu.
  • Mitsubishi.
  • Caterpillar.
  • Farymann.
  • Shibaura.

Why should I switch to electronic governing?

The GAC range of electronic governing systems make it simple to get maximum productivity from your engines and gensets.

With electronic governing:

  • Gensets maintain a constant frequency whatever the load. Sensitive electronic equipment is protected against damaging fluctuations. This is especially important in IT and healthcare.
  • Engines respond faster to load changes – as much as 200 times faster.
  • You improve your fuel economy because an electronic governor accurately sets the engine’s throttle to match the load. That reduces your bills and also your environmental footprint.
  • You avoid the massive disruption of installing a new engine from scratch.
