  • 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

The ISOMETER® isoMED427P monitors the insulation resistance of unearthed AC circuits (medical "IT systems"). At the same time, the load current and temperature of the IT system transformer is monitored. In combination with EDS series insulation fault locators and the appropriate measuring current transformers, the isoMED427P is designed to set up the respective equipment for insulation fault location.
