Innovative technologies for safe handling of electrical power to achieve high availability

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


Series VIT-AFSBY isolated power panels are equipped with an isolation transformer as well as with a changeover and monitoring module including all necessary monitoring components as to DIN VDE 100-710 for IT systems:

  • Changeover device and voltage monitoring
  • Insulation monitoring
  • Load and temperature monitoring
  • Insulation fault locator
  • Bypass Switch

The secondary side of the isolation transformer is equipped with at least 6 two-pole circuit breakers. Group 2 sockets are being connected to these.
In order to reduce or avoid noise disturbance by air circulating fans, waste heat is conducted by free convection.


  • Automatic changeover and monitoring device ATICS® including monitoring of i.e.:
    - Voltage of incoming supply
    - Output voltage
    - Correct operating times
    - Changeover times
    - Insulation resistance
    - Load current
    - Transformer temperature
    - At least 6 two-pole circuit breakers B16A
    - Insulation fault monitoring device (EDS)
    - Bypass switch
    - Isolating transformer (3150VA – 8000VA)
  • Variable changeover time t ≤ 0.5 …15s
  • Exchange of information by means of bus technology
  • Connection facility for remote alarm and operator panels MK2430 / TCP
  • Sheet steel housing as to DIN VDE 0100-710 (VDE 0100-710): 2002-11, section 710.51.2.2.
  • Designed in accordance with the requirements of applicable standards
  • Voluntary certification of changeover device by the independent German technical service, testing and inspection organization (TÜV)


  • For intesive care units with equiment for insulaion fauls location
