Description

The CM-UFD.M22M is a multifunctional grid feeding monitoring relay with Modbus RTU communication interface. It provides different monitoring functions in accordance with CEI 0-21 to detect over- and undervoltage (10-minutes average value, voltage increase and decrease protection) as well as any changes in grid frequency (frequency increase and decrease protection). Additionaly, monitoring of ROCOF (rate of change of frequency) can be configured.
