Main and isolation


      • Rating: up to 1kVA
      • Isolation class according to request
      • Epoxy resin
      • Self-extinguishing plastic UL94-VO
      • Test at 100% of all electrical parameters in production


  • Minimum size at high output
  • Double output voltage for series or parallel connection
  • Designed for high ambient temperatures
  • Permanent corrosion protection
  • High insulation value
  • Maximum electrical reliability due to encapsulation with epoxy resin
  • Potting components can comply to  UL requirements
  • Coil shell in 1 or 2 chamber technology


  • Emergency lighting, street lighting, power supplies for IT, automation, metering and robotics
  • Mains, isolation and safety transformers used for the safe electrical isolation of the input and output sides, to set up protective separation as a protective measure, adjustment of the voltage and simple electrical  isolation, they are suitable for creating SELV and PELV circuits
    because of the limit on the output voltage.
