CM-UFD.M33M Grid Feeding Monitoring Relay Data Sheet

This data sheet describes the CM-UFD.M33M, a multifunctional grid feeding monitoring relay with Modbus RTU communication, designed to disconnect distributed generation from the public grid during faults or instability. It monitors voltage and frequency (including 10-minute average, ROCOF, and vector shift) in single- and three-phase systems, featuring adjustable thresholds, tripping delays, three control inputs, three output relays, and an LCD display.
