DATAKOM DKG-253 Generator engine governor controller for actuators

* All prices are retail and VAT exclusive

The DKG-253 is a low cost electronic governor control unit designed to control the engine speed with fast and accurate response to load changes. The unit is housed in a metallic chassis and consists of a single enamel coated printed circuit board for reliable operation in harsh automotive environment.

The unit features an adjustable internal overspeed alarm relay with indicating led. This relay provides supplementary speed protection in case of speed control failure.

The DKG-253 connects to a forward acting proportional electric actuator and a magnetic speed sensor. It  is able to control a wide variety of engines in constant speed (isochronous) or droop modes.

An external speed trim potentiometer may be connected to the unit to adjust the engine speed from a remote location.

The unit is capable to deliver actuator currents as high as 10 Amps. However the output current limiting circuit will protect the unit against output short circuits.

Protection against reverse battery connection and transient voltages are provided.
