TRT SERIES

POLYLUX’S TRT SERIES

Three phase rectifier trasnformers

The TRT series consists of cast resin three-phase rectifier transformer rectifiers, designed to supply continuous loads when a three-phase power network is available.

They are cast resin, making them particularly suitable transformers for working in areas where high resistance to vibrations, overcurrent and transient harmonics is required, as well as in humid, saline and corrosive environments.

These series are subdivided according to their output voltages:

  • TRTA 400Vac input and 12Vdc output
  • TRTB 400Vac input and 24Vdc output
  • TRTC 400Vac input and 48Vdc output

The transformers these series have a rating of 1.6Adc – 63Adc.

Constructive features:

  • Terminal protection cover.
  • Mounted with screws.
  • Electrical feature and connection label.
  • Protection against humid, saline and corrosive environments.
  • Greater mechanical resistance to vibrations, surge currents and electrodynamic stress.
