When Power is Critical
Electronic engine governing
Improve response speed and avoid droop
with GAC electronic governing
GAC electronic engine governing
series
Older, mechanically-governed engines and gensets are often one step away from the scrap heap.
Our natural reaction is to replace them with a
newer unit.
Electronic governing can breathe a new lease of
life into older engines that are mechanically
governed.
They are suited for many gen-sets, compressors
and other applications and are compatible with a
wide range of engines including Perkins, Yanmar
and Kubota.
GAC electronic governing products feature a high
quality construction and come with sealed
automotive connectors for a lifetime of use. They
are also specifically designed for high temperature
operation.
Responsive
Electronic governors are up to 200 times faster
than mechanical governors. This means that there
is no droop on gen-sets, and power stays constant
under variable loads on pumps and other engine
applications.
Economical
Electronic governing will accurately set the
engine’s throttle to match the load, improving fuel
economy. That will reduce your bills and your
environmental footprint.
Reliable
GAC electronic governing features precision linear
ball bearings and a minimum of moving
parts to increase reliability.

How does electronic governing help you?
Extend capabilities
Boost performance
It’s easy to run older gensets parallel to mains or to
other gen-sets when
electronically governed.
Load response improves
thanks to the speed of an
electronically-controlled
actuator. It can be up to
200 times faster than a
mechanical governor.
Protect equipment
Save capital expense
Isochronous speed control
supplies a constant, nodroop frequency to
sensitive electrical
equipment, whatever the
load.
Upgrading an existing
engine or gen-set is less
expensive than buying a
new one. Electronic
governing gives extra
performance economically.
Expert assistance
Go green
IPU is GAC’s longestserving distributor in the
world. With decades of
experience we can help
you through all pre and
post-sales challenges.
Electronic governing
reduces fuel consumption
and avoids the
environmental footprint of
a new engine or gen-set.

Winches
With electronic governing older gen-sets can supply consistent, reliable power
to sensitive equipment such as IT and healthcare systems. By adding
isochronous speed control and paralleling options you can bring older
equipment back into active use without the expense of a major upgrade.
Electronic governing can be economically applied to engines in applications
from irrigation pumps on farms to lifting gear in mines.
With much faster response to transient load changes, electronically-governed
engines provide smoother, more consistent power to the equipment they
serve.
Electronic governing systems reduce fuel consumption and environmental
impact because they move the throttle to any position between fully open and
fully closed. Mechanical governors use full throttle even under a modest load.
Upgrading to electronic governing
The Actuator
The actuator replaces the engine’s mechanical throttle. Electronic actuators
deliver fast, precise throttle control.
 Load response improves because actuators react 200 times faster than
mechanical throttles.
 Fuel economy improves because actuators can move to any position
between fully open and fully closed. If you need 50% power they open the
throttle 50%. Mechanical throttles are either open or closed.
 It is a non-contacting design, so no maintenance is required
The Governor
The governor is the brains of the system. Electronic governors deliver fast, nodroop response to load changes and isochronous speed control for gen-sets.
 Digital and analogue controllers are available for different applications.
 Optional load-sharing modules are available for isochronous paralleling
with other gen-sets, load sharing and mains power control.
 Digital controllers are extremely flexible—can be fed with various speed
request inputs such as throttles, levers, pots and PLCs.
The Pickup
The magnetic pickup attaches to the flywheel casing. It feeds accurate speed
data back to the controller so engine performance can be monitored and
adjusted.
 A wide variety of magnetic pickups are available for engines from
Farymann, Isuzu, Kubota, Mitsubishi, Perkins, Shibauru and Yanmar.
