DATAKOM VOLTAGE REGULATOR AVR-20

The DATAKOM AVR-20 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.

  AVR-20 DATAKOM AVR measures the voltage between one of the alternator phases and the neutral point and adjusts the DC voltage applied to the excitation winding until reaching the desired voltage.

  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. A stability adjustment potentiometer is also provided for this purpose.

  The AVR-20 AVR20 DATAKOM AVR has a special relay-less electronic circuit design. The required minimum residual voltage for build up is 5 VAC. The unit does not include moving parts; therefore it is able to operate in highly vibrating environments.

The DATAKOM AVR-20 AVR20 AVR includes a low frequency protection circuit. This feature reduces the output voltage during overload or engine stop. Therefore the diesel engine is protected from excessive torque generated by high startup currents of large electrical equipments. Similarly, the diesel engine may be stopped under load without damage.

 The easy connection scheme of the device allows fast and easy replacement.
