The GAC ECC328 governor is designed to control engine speed with precise response to transient engine load changes and is suitable for single running applications.

GAC ECC328 electronic governor

The GAC ECC328 offers fast response to transient load changes and improved productivity

It features closed loop speed control and when supplied with a speed signal/ frequency from the main AC generator, it will control a wide variety of engines in an isochronous mode.

Isochronous speed control supplies a constant frequency of electricity under varying loads – so there will be no generator droop or overshoot. Overshoot is just as problematic as droop and can spell bad news for sensitive equipment such as IT and healthcare systems. The inclusion of isochronous speed control will eliminate the danger of these occurrences.

The ECC328 is able to produce the speed signal internally, so no additional Magnetic Pickup Sensor is required. The lack of a Magnetic Pickup Sensor gives this system a lower cost than others.

Other features also include:

  • Isochronous Operation.
  • No Magnetic Speed Pick-Up Required.
  • For Genset Only/Max 260 VAC.
  • Rugged Hard Potted Design.
  • Gain And Stability Adjustments.
  • Lower System Cost.

Standard features also include protection against:

  • Reversal of the battery supply.
  • Accidental shorts in the actuator wiring.
  • High voltage transient on the DC and AC lines.
  • The loss of the speed signal or battery supply.


Will the GAC ECC328 governor fit my brand of engine?

The GAC ECC328 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.
