  • ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems).
  • Automatic adaptation to the existing system leakage capacitance.
  • Combination of AMPPLUS and other profile-dependent measurement methods.
  • An adjustable response value for insulation monitoring in the range of 1 kΩ…10 MΩ (factory setting = 5 kΩ) and a response value of 150 V for the DC offset voltage.
  • High-resolution graphic LC display for excellent readability and recording of the device status.
  • Connection monitoring (monitoring of the measuring lines).
  • Automatic device self test.
  • Graphical representation of the insulation resistance over time (isoGraph)
  • History memory with real-time clock (buffer for three days) for storing 1023 alarm messages with date and time.
  • Current or voltage output 0(4)…20 mA, 0…400 μA, 0…10 V, 2…10 V (galvanically separated) which is analogous to the measured insulation value of the system.
  • Freely programmable digital inputs and outputs.
  • Remote setting via the Internet or Intranet (Webserver/Option: COMTRAXX® gateway).
  • Worldwide remote diagnosis via the Internet.
  • BCOM, Modbus TCP and web server.
  • AC/DC main circuits with directly connected DC components, such as rectifiers, converters, variable-speed drives
  • Systems including switch-mode power supplies
  • Systems including frequency inverters
