AUTFX

Features

Dry type autotransformer.

All autotransformers are tropicalized with anti-flash varnish:

  • Protection against corrosive environments.
  • Greater electrical insulation.
  • High compaction power.
  • Noise level reduction.
  • Longer useful life of the product.

Safety class I

Includes lifting bolts from 50 kVA.

Tailor made if the standard specifications are not what is required.

Applications

  • These devices are used to reduce the output voltage of inverters from 800V to 400V. Therefore, achieving the working tension required by the client.
  • If you need other working voltages, they can be manufactured upon request.

Available accessories

  • Class II.
  • Wheels
  • PT100, PTC or Bimetallic probes.
  • C5 paint.
  • Several RAL.
  • Electric temperature panel.
  • Anti-condensation system.
  • IP up to IP-65.
