Product description
The insulation monitor IL 5881 of the series VARIMETER IMD monitors the insulation resistance of non-earthed DC systems (IT-systems) with nominal voltage up to DC 12 ... 280 V. The supply voltage (auxiliary voltage) is taken from the monitored system. The device has LEDs to indicate the operating status. The response value can be set in a user-friendly way on the front of the device via a potentiometer.
