ABB CM-UFD.M22 multifunctional grid feeding monitoring relay with 24-240 V AC/DC supply, 0-550 V AC monitoring range and three changeover outputs for renewable energy applications.
The ABB 1SVR560730R3400, also known as the CM-UFD.M22, is a multifunctional grid feeding monitoring relay developed to provide reliable interface protection between distributed power generation systems and the public electricity grid. It continuously monitors voltage and frequency conditions to ensure safe operation and compliance with grid connection requirements.
Designed for renewable energy applications, the CM-UFD.M22 supervises critical electrical parameters including overvoltage, undervoltage, overfrequency and underfrequency. When abnormal conditions are detected, the relay activates external switching devices to safely disconnect the generating installation from the grid until acceptable operating conditions are restored.
Supporting a phase-to-phase measuring range of 0-550 V AC and powered from a wide 24-240 V AC/DC control supply, the CM-UFD.M22 is suitable for photovoltaic systems, distributed generation installations and industrial grid interface panels requiring dependable network monitoring.
The ABB CM-UFD.M22 continuously measures grid voltage and frequency to verify that electrical network conditions remain within programmed limits. If abnormal conditions occur, the relay activates external switching equipment to isolate the generation system, helping protect both the installation and the public electricity network.
Its comprehensive monitoring functions and flexible control supply make it suitable for a wide variety of grid-connected renewable energy applications where dependable interface protection is required.
