We offer you first-class quality and safety combined with global service and every support in resolving your monitoring problems.

  • Electrical safety for unearthed power supplies (IT systems)
  • Insulation monitoring equipment, insulation fault location systems
  • Power supplies for medical applications
  • Measuring and monitoring relays
  • Electrical safety for earthed power supplies (TN systems)
  • Using renewable energies efficiently: wind power, photovoltaics
  • Test systems for electrical equipment and medical technology


  • Increase of the ISOMETER® nominal voltage range
  • Application with ISOMETER® IRDH275BM-7
  • For medium-voltage applications up to AC/DC 7.2 kV (AGH675S-7)
  • For medium-voltage applications up to AC/DC 15.5 kV (AGH675S-7MV)

The coupling device AGH675S-7/AGH675S-7MV15 series is designed to extend the nominal voltage range of the ISOMETER® IRDH275BM-7. The coupling device is connected to the system to be monitored by one pole and connected to the terminal AK of the ISOMETER® by means of the terminal 5.
