DATAKOM AVR-12 Automatic voltage regulator for generator alternators. ATS, AMF, AVR, ECM, DKG controllers for diesel, gas, petrol gensets including manual start units and auto mains failure generator

DATAKOM AVR-12 Voltage Regulator is an electronic device which lets the alternator to produce fixed output voltage. It has open chassis, resin molded design and is intended to be mounted in the alternator’s terminal box.

The output stage of the device is a Half Wave tyhristor output associated with a free wheeling diode. Basically the unit is compatible with all brushless type alternators.

The AVR-12 has a special relay-less electronic circuit design. The unit does not include moving parts; therefore it is able to operate in highly vibrating environments.

The AVR-12 includes a low frequency protection circuit. The easy connection scheme of the device allows fast and easy replacement.

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.
