Description of Change: A new Digital Voltage Regulator is now being used. The Caterpillar Digital Voltage Regulator (CDVR) will increase performance and increase reliability. The microprocessor-based CDVR will also provide precise voltage control, robust transient response, and generator protection. Adaptable To: The CDVR will be used in production only on PMG generators that have the CDVR as standard or as an option. Self-excited generators or generators that do not have an option for the digital voltage regulator will not be affected. The CDVR is a replacement for analog voltage regulators that are utilized in high voltage applications (i.e., KCR760 and K65-12B).SIS Web Download
