ISOMETER® isoMED427P

ISOMETER® isoMED427P

  • Insulation monitoring device for medical IT systems
  • Load and temperature monitoring for IT system transformers
  • According to IEC 60364-7-710, IEC 61557-8 and 61557-9
  • Locating current injector for insulation fault location systems
  • Can be extended to operate as an insulation fault location system

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 detection of an insulation fault, the internal locating current injector of the isoMED427P-(xx) models enables insulation fault location. The use of special devices of the EDS series is recommended to locate the insulation fault.
Devices of the isoMED427x-(PT) series do not require an additional supply voltage. The maximum permissible system leakage capacitance is 5 μF.
In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions.
