DATAKOM AVR-5 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-5 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. The unit does not include moving parts; therefore it is able to operate in highly vibrating environments. The AVR-5 includes a low frequency protection circuit. The easy connection scheme of the device allows fast and easy replacement. FEATURES: Half-Wave tyhristor output, 0-5 amps. output current, 0-115 volts output voltage, Relay-less circuit design, Low frequency protection, Built in voltage adjustment, Stability adjustment, Remote voltage adjustment feature, Easy connection scheme, Compatible with various types of alternators.
