Dold UH5892.11PS 0066946 Isolation monitor No. of relay outputs: 1

The insulation monitor UH 5892 of the VARIMETER IMD series monitors the insulation resistance of ungrounded DC and AC power systems (IT systems) with rated voltages of DC 0 ... 600 V and AC 0 ... 400 V. Symmetric as well as asymmetric insulation faults are detected. The separate supply voltage (auxiliary voltage) of AC/DC 24 ... 60 V OR AC/DC 85 ... 230 V also enables the monitoring of a de-energized system. An LED chain and an analogue output are used to display the current insulation resistance. In the event of fault detection, the detector relay switches and the red "ALARM" LED lights up. The device is suitable for network leakage capacities of up to 20 μF.

Benefits:
Preventive fire and equipment protection
Insulation monitoring of DC and AC networks up to 600 V DC and 400 V AC nominal voltage
No additional ballast required
Suitable for network leakage capacities up to 20 μF
Monitoring even with voltage-free mains
2 wide-voltage ranges for the auxiliary voltage
