Step-up and step-down transformers

Product catalog summary
Overview: POLYLUX specializes in manufacturing high-quality three-phase isolation transformers, available in both step-up and step-down models, designed for continuous industrial operation.
Key Features:
  • Varnished and compacted transformers for noise reduction and moisture protection.
  • Copper connections, with aluminum coil options using bi-metallic connections.
  • Encapsulation in flame-retardant resin, compliant with UL94 V0 standards for thermal resistance.
  • Optimized magnetic cores for high efficiency.
  • Available in flexible constructions with IP23 and IP65 enclosures.
  • Automatic testing ensures standard compliance.
Product Range:
  • TTU Series: Step-up transformers with 230V input and 400V + N output, power ratings from 0.63 kVA to 1000 kVA.
  • TTD Series: Step-down transformers with 400V input and 230V output, enhancing electrical network quality.
Technical Specifications:
  • Standard frequency: 50-60 Hz.
  • Insulation classes: Class F (155°C) and Class H (180°C).
  • Safety class I, operational altitude up to 1000 m.
  • Various IP ratings (IP00, IP23, IP54/65) depending on the model.
  • Compliance with IEC/EN 61558 and IEC/EN 60076 standards.
Recommendations:
  • Encapsulated transformers are recommended for fire retardant properties and use in damp or corrosive environments.
  • IP00 models are suitable for dry, protected environments.
  • Ecological models offer lower consumption and faster amortization.
Customization Options: Transformers can be customized for power from 0.15 kVA to 1000 kVA, voltage from 1 V to 12 kV, and frequency from 50 Hz to 400 Hz, with options for copper or aluminum windings.
