CAT Digital Voltage Regulator v252-7515-01

The Caterpillar Digital Voltage Regulator (CDVR) is a microprocessor based control designed to provide precise voltage control, robust transient response, and generator protection with industry leading features and versatility. 

● Microprocessor based control featuring choice of three control modes standard: 
- Automatic Voltage Regulation (AVR) 
- Power Factor Regulation (PF) 
- Reactive Power Regulation (Var) 


● Programmable stability settings. 
● Soft start control with an adjustable time setting in AVR control mode. 
● Dual Slope Underfrequency (volts/hertz)regulation. 
● Three-phase or single-phase generator voltage(RMS) sensing/regulation in AVR mode. 
● Single-phase generator current sensing for regulation purposes. 
● Field current and field voltage sensing. 
● Five contact sensing inputs for system interface. 
● One common LED for visual indication of Alarm and Shutdown fault conditions. 
● Fault Shutdown Driver and Alarm Output Driver for indication of Alarm and Shutdown fault conditions. 
● Generator paralleling with reactive droop compensation and reactive differential compensation. 
● Line drop compensation. 
● Remote communication interface via CAN 2.0B. 
● Ten generator protective functions. 
● UL 508A Recognized and CE certified.
