TTKW

TTKW

Isolation transformer.

Features

Dry type transformer

Dipped in anti-flash varnish and then compacted in the oven. This process increases the insulation grade, reduces noise and provides anti-moisture, waterproofed protection.

Metalic box IP-23 enclosure painted with Polyester resin RAL 7035 (cat. C3 ISO 12994-2).

Inverted V/v connection.

Includes lifting eyebolts.

Possibility of tailor-made manufacturing.

Applications

  • TTK transformers are used for the galvanic isolation of electrical installations for safety reasons.
  • TThe TTK series with three-phase input and single-phase output are used to achieve a better balance of the primary currents than by connecting only one phase and one neutral of a three-phase line.
  • With the three-phase transformer it is also possible to connect a single load of up to half the mains rating.
  • In installations where many single-phase loads have to be connected to the same line, the three-phase transformer can also help to make more rating available on that line.

Available accessories

  • Protections in primary and secondary.
  • One, two and up to 3 electrostatic screens.
  • Class II
  • Wheels.
  • PT100, PTC or Bimetallic probes.
  • Painting C5.
  • Different RAL.
  • Temperature control unit
  • Anti condensation system
  • Different IP up to IP-65
