AVR-8 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 unit does not include moving parts; therefore it is able to operate in highly vibrating environments. The device measures phase to neutral or phase to phase voltage of the alternator and adjusts the DC voltage applied to the excitation winding until reaching the desired voltage.
The unit offers low-frequency protection feature. The nominal frequency can easily be changed to 50 or 60 Hz in the field by push-on link selection. 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. Analogue input is provided allowing external voltage adjustment.
The AVR-8 has the facility for droop CT connection, to allow parallel running with other similarly equipped generators. An overload protection circuit limits the output current to its nominal value, preventing device failure under overload or short circuit condition.
The device can be connected as phase-to-phase instead of default phase-to-neutral to be used in 120/208 VAC 60Hz alternators.
