Rectifier Transformer

Rectifier transformers are used for industrial processes which require direct current supply. These markets include DC traction, electrolysis, furnace operations, and large variable speed drives.

Features

  • Power rating up to 3000 KVA
  • Up to 25 kV class, 125 kV BIL
  • Transformers drive 6, 12, 18, 24 and 36 pulse rectifiers
  • Multiple phase shifting options for 12 pulse and higher systems:
    • Delta/Wye
    • Extended delta for leading or lagging phase shift
  • For applications not requiring voltage transformation or isolation, auto wound phase shifting transformers (polygon, differential fork, etc.)
  • Three phase design
  • Frequency: 50 and 60 Hz standard – Inquire about other frequencies
  • Self-cooled, forced air cooled, or water-cooled construction
  • Aluminum or copper windings

 

Optional

  • UL Recognized insulation system (Primary must be 600V or less). MSI UL Insulation systems are available in 130°, 180° and 220°C ratings
  • CE marking with declaration of conformity ROHS and Low Voltage Directive where applicable
  • Private labeling with customer supplied nameplate artwork. Units that are private labeled cannot carry our UL label
  • NEMA 1 (indoor) or NEMA 3R (outdoor) enclosure with ANSI 61 gray powder coat finish
  • Temperature monitoring thermal switches, thermocouples, or platinum RTDs
  • Final Test Reports with optional Certificate of Compliance
