ISOMETER® IR1575 Insulation monitoring device for unearthed AC/3(N)AC systems up to 480 V and DC systems up to 480 V

Insulation monitoring device for unearthed AC/3(N)AC systems up to 480 V and DC systems up to 480 V Product description The ISOMETER® of the IR1575 series monitor the insulation resistance of unearthed main circuits (IT systems) AC, 3(N)AC 0…480 V resp. DC 0… 480 V. The AMP measurement method allows the Isometers to be used in systems with directly connected DC components. Taking the system leakage capacitances into account, the IR1575 automatically adapts itself to the existing system conditions in order to optimise the measuring time. An external supply voltage allows de-energised systems...
