POLYLUX’S SERIE TMTX | TMTW | TMTE

Three phase transformers designed to adapt the voltage for measurement equipments.

The TMT series is made up of three-phase measuring transformers that includes a rating range as from 15VA up to 400VA and are intended to adapt the voltage for measurement equipment.

Its function is to provide a precise voltage at the output, isolating it from the input. On the one hand, it is possible to reduce the voltage to a lower high-precision value and, on the other hand, it is possible to isolate the high-voltage circuit from the measurement circuit.

Constructive features:

  • Connection terminals made of copper, welded and inserted in blocks to prevent hazards caused by expansion that may lead to poor connection.
  • Built with independent circuits for the three phases to obtain a perfect balance between them and guarantee precision in measuring.
