Product information "CAPDIS-4o_HF"
The CAPDIS-4o amplifier provides an output voltage of 3 x 100 or 110 VAC in conjunction with three resistive sensors and thus serves as a substitute for three inductive voltage transformers.


  • Connection of protective relays with conventional 100 VAC voltage measurement input
  • Connection of universal measuring devices and network analyzers
  • for critical safety applications (no ferroresonance)
  • Retrofitting even in confined spaces

Precise and economical

  • Economical alternative to outgoing voltage transformers

Safety and handling advantages

  • minimal space requirement

  • no additional measuring field

  • no disassembly required for surge voltage tests

  • no ferroresonance hazard
