Caterpillar Digital Voltage Regulator (CDVR)

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

CAT CDRV features:
. Microprocessor-based control featuring a choice of three control modes standard:
1.Automatic Voltage Regulation (AVR)
2.Power Factor Regulation (PF)
3.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 an 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.
