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.
- IP-65 up to 63 kVA and IP-54 as from 80 kVA (for IP-65 degree consult us) enclosure, metal enclosure painted with RAL 7035 polyester resin (cat. C4 ISO 12994-2).
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.
