Generator Automatic Voltage Regulator Cummins AVR 314-7755

The Caterpillar Digital Voltage Regulator (CDVR) is a microprocessor based voltage regulator. The main purpose of a digital
voltage regulator is to regulate the output voltage of a generator that is used with an engine generator set. Control power for
the Digital Voltage Regulator is supplied from an external 24 DCV source. The power stage of the Digital Voltage Regulator can be
supplied from a multi-pole, high frequency, permanent magnet generator (PMG),from the generator output (shunt excitation), or from
auxiliary windings that are included on some generators. Connections to the Digital Voltage Regulator are made through three
multi-pin, plug type connectors. The communication between the Digital Voltage Regulator and a service tool is accomplished using
a CANBUS protocol.
