TTDNZ

Features

Dry type transformer

Anti-flash varnish finish, offering:

  • Protection against corrosive environments
  • Increase of electrical isolation
  • High compression capacity
  • Reduction of noise level
  • Increase of product’s lifespan

IP65 metal enclosure up to 31.5 kVA and IP54 from 40 kVA (please enquire regarding IP65 rating), painted with RAL 7035 polyester resin (cat. C4 ISO 12994-2 up to 6.3 kVA and cat. C5 ISO 12994-2 from 8 kVA)

Possibility of tailor-made manufacturing

Applications

  • TTDN transformers are the ideal solution for safely adapting the output voltage of solar inverters to a grid voltage suitable for the installation, reducing the voltage from 400 V to 230 V.
  • Are used for galvanic isolation of three-phase solar installations.
  • Changing the neutral system of an installation
  • They help improve the quality of the electrical network on the secondary side, especially in installations with a certain level of electrical noise.

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
