Bender B71036402 Insulation monitoring

The A-ISOMETER® IR425-D4-2 monitors the insulation resistance of ungrounded AC/DC control circuits (IT networks 0 - 300 V). The DC-powered components present in AC/DC systems do not affect the response behavior of this device. Thanks to the separate supply voltage, monitoring of the de-energized system is also possible. A password or the sealable transparent cover protects against unwanted changes to set limit values. An insulation monitoring device from Bender guarantees the safe construction of isolated, single-fault tolerant AC/DC supplies.
