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


The ATICS® transfer switching devices provide all functions for changeover between two independent power supplies. The integration of both the electronic system and the switching elements in one flat, compact device reduces space requirements in the switchgear cabinet, minimises the amount of wiring, and reduces the fault probability. For maximum reliability, ATICS® was designed in strict accordance with the guidelines for functional safety. 

Connectors at all connecting wires in combination with bypass switches enable ATICS® to be tested during ongoing operation. In case of need for service, it is possible to repair or replace the device without interrupting the power supply. ATICS® considerably enhances the safety level in industry and other sensitive environments like hospitals.


Perfectly suitable for space-saving installation/retrofitting

  • Compact device for designing safety power supplies with functional safety more easily, in accordance with DIN VDE 61508 (SIL 2), in computing centres, industry, or in group 2 medical locations in accordance with DIN VDE 0100-710 (VDE 0100-710)/IEC 60364-7-710
  • All-in-one: Integration of switch disconnector and control electronics
  • Compact design
  • Solutions for any application

Convenient installation and commissioning

  • Saves time and money

Safe operation

  • Switch disconnector contacts of robust design
  • Mechanical locking
  • Manual operation directly on the device
  • Functional safety SIL 2
  • Certification by TÜV SÜD

Uninterrupted maintenance

  • Plug connectors and optional bypass switch
  • Excellent communication and parameterisation options


  • Where sensitive electrical installations are involved, e.g. in medical locations of Group 2, industry or computing centre, safe and reliable power supply must be ensured, also in the event of malfunctions. Redundant supply lines significantly contribute to achieve safe and secure power supply.
