Integrated Voltage Detecting System DSA-i3

The DSA-i3 integrated voltage detecting system with integrated indicator is designed for the installations in switchgears. An additional display makes in-service tests unnecessary. This voltage detecting system is therefore particularly maintenance-free, reliable and cost-effective when used in continuous operation.

For use in interface requirements according to EN 61243-5 oder EN 61271-213.

  • No external power supply required
  • Red LCD display
  • Test sockets for performing a phase comparison
  • Additional third socket for testing the integrated LCD display
  • Secure cover for sockets
  • Conscious test process using three buttons
  • Integrated breaking point for voltage-limiting
  • Simple assembly
  • No in-service tests required
  • Interface adaptation possible by means of additional capacitances
  • Protection class IP 66
  • Operating temperature -25...+55°C
  • Dimensions (mm): width 96 x height 48 x depth 30
