  • ISOMETER® for AC IT systems with galvanically connected rectifiers or converters and for DC IT systems (IT = unearthed systems)
  • Automatic adaptation to the existing system leakage capacitance
  • Combination of AMPPlus and other profiledependent measurement methods
  • Two separately adjustable response value ranges of 1 kΩ…10 MΩ
  • High-resolution graphic LC display
  • 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 13 days) for storing a maximum of 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 (web server/option: COMTRAXX® gateway)
  • Remote diagnosis via the Internet (only by Bender service)
  • RS-485/BS (Bender sensor bus) for data exchange with other Bender components
  • ISOnet: Internal separation of the ISOMETER® from the IT system to be monitored (e.g. if several IT systems are interconnected)
  • BCOM, Modbus TCP/RTU and web server
  • Nominal system voltage can be expanded via coupling device
  • AC, DC or AC/DC main circuits
  • AC/DC main circuits with directly connected DC components, such as rectifiers, converters, variable-speed drives
  • UPS systems, battery systems
  • Heaters with phase control
  • Systems with switch-mode power supplies
  • IT systems with high leakage capacitances
