Custom products

Toroidal transformers can be designed in any sizes (height and diameter) as well as having additional primary and secondary voltages or tappings as required. The toroidal transformer is characterised by being more efficient, smaller, quieter and having superior EMC properties compared to the traditional laminated transformer.

We makes customised toroidal transformers and inductors in sizes up to 20 KVA per phase. Sizes can be limited within the series due to the specific standard mounting parts. Special parts can be made.

Industrial series UL marked (UL506) up to 5 kVA.

Medical series UL marked (UL60601-1) up to 10 kVA for 105°C, 130°C and 155°C.

Current transformers (EN61869-2) tested with up to 5kA primary current.

Potted transformers are typical in standard boxes – special boxes can be made.

Special windings for any application.

Typical options are offered:

• UL class B insulation system for 130°C
• UL class F insulation system for 155°C
• UL class H insulation system for 180°C
• Built-in fuse or fuse holder
• Built-in thermal protection by thermal switch or thermal fuse
• Clips
• Connectors
• Cable / cable with connector
• DIN Rail mountings
• Varnishing
• Vacuum impregnation
• Resin moulding in box (potting)
• Vacuum moulded in box
• Vertical / tall or horizontal / low profile design

All transformers are made according to EN61558 - unless otherwise agreed.

All transformers are tested before despatch.
