The ISOMETER® IRDH275 insulation resistance monitor monitors the insulation resistance of IT systems. It is suitable for 3(N)AC, AC/DC, and DC systems. AC systems may contain a large number of DC-supplied loads, such as converters or thyristor-controlled DC drives. The device automatically adapts to the existing system leakage capacitance. Suitable coupling devices are also available to extend the nominal voltage range Un. The IRDH275B can be used with control and indicating devices on the BMS (Bender Measuring Device Interface) bus (e.g., PRC1470 version 2 or higher).
