DATAKOM AVR-4 voltage regulator is a electronic device which lets the alternator to produce a fixed output voltage.

The device has open chassis, resin molded design and is intended to be mounted in the alternator's terminal box. The unit does not include moving parts; therefore it is able to operate in highly vibrating environments.

The device measures phase to neutral of the alternator and adjusts the DC voltage applied to the excitation winding in order to reach the desired voltage.

The unit offers low-frequency protection feature. A frequency measuring circuit continually monitors the generator output and provides low-frequency protection of the excitation system, by reducing the output voltage proportionally with frequency below 45Hz.

The excitation power is derived directly from the generator terminals. The required minimum residual voltage for build up is 2 V-AC.

The output stage of the device is a Half Wave thyristor output associated with a free wheeling diode.

Basically the unit is compatible with all brushless type alternators. A stability adjustment potentiometer is also provided for this purpose.
