Open the catalog to page 1

Insulation monitoring device with integrated load and temperature monitoring and locating current injector for insulation fault location systems for medical IT systems Product description ISOMETER®s of the isoMED427x-(PT) series monitor the insulation resistance of a medical IT system with AC 70…264 V. In addition, the load current and the temperature of the IT system transformer are monitored. Alarms and measured values are provided to other bus devices via the BMS interface. For display and signalling purposes, the use of special alarm indicator and test combinations is recommended. After...
