AVR-12 Voltage Regulator is an electronic device which lets the alternator to produce a fixed output voltage. It has open chassis, resin molded design and is intended to be mounted in the alternator’s terminal box
AVR-12 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 thyristor output associated with a freewheeling diode. Basically the unit is compatible with all brushless type alternators. A stability adjustment potentiometer is also provided for this purpose
The AVR-12 has a special relay-less electronic circuit design. The required minimum residual voltage for build-up is 5 V- AC. 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. This feature reduces the output voltage during an overload or engine stop. Therefore the diesel engine is protected from excessive torque generated by high startup currents of large electrical pieces of equipment
Similarly, the diesel engine may be stopped under load without damage. The easy connection scheme of the device allows fast and easy replacement
