ISO-CHECK

ISO-CHECK is the series of IMD devices for continuous monitoring of insulation resistance for isolated AC networks (IT), isolated photovoltaic (PV) installations and installations for charging electric vehicles (EV), in DIN rail format for panel mounting. Complies with standards IEC 61557-8 and CHAdeMO 0.9.

  • Insulation defects in AC networks with IT isolated earthing system, and isolated DC networks can lead to the appearance of dangerous contact voltages. This is why international regulations, require the use of insulation monitoring on any type of isolated network.
  • In the event of an insulation fault, a measurement circuit is closed and a current flows through the monitor which is proportional to the fault, making it possible to calculate and compare it with the minimum threshold set.
  • ISO-CHECK IT is the series of IMD devices for continuous monitoring of insulation for a wide range of isolated AC systems: Command and control circuits in industrial installations, mobile current generators, lighting circuits, power supply circuits for motors, pumps and ventilation.
    For nominal system voltage Un: 440 Vac. According to IEC 61557-8.
  • ISO-CHECK PV is the series of IMD devices for continuous monitoring of insulation for isolated DC photovoltaic networks.
    For nominal system voltage. Un: 600 and 1.000 V at 50/60 Hz. According to IEC 61.557-8.
  • ISO-CHECK EV is the series of IMD devices for continuous monitoring of insulation for isolated DC networks for charging electric vehicles (EV).
    For nominal system voltage Un: 500 Vac. Complies with IEC 61557-8 and CHAdeMO 0.9.
  • All models have front adjustment, test button and remote actuation signal.
