Product description

The insulation monitor RP 5888 of the VARIMETER IMD family provides best and up to date insulation monitoring of AC-IT systems. The measuring principle is overlay with DC-measuring voltage. The setting of the parameters and the switching values is done by simple and operator friendly rotational switches on front of the device. The operating status is indicated user friendly via three multicolour LEDs. In addition the actual insulation resistance value is available on an analogue output.
