Radiotone Toroidal Transformer

Major Applications : Windmill / Solar & Energy Saver Applications

Radiotone Toroidal Transformers are silent in operation, compact in size, less weight and are ideally suitable for 24/7/365 operation due to very low no load losses.

Radiotone Toroidal Transformer Isolated (DW) type

  • Capacity 50VA to 12 KVA
  • Three Phase Assembly
  • High Efficiency

Radiotone Energy Saver Toroidal Transformer Auto Type

  • Capacity up to 30 KVA
  • Three Phase Assembly
  • Efficiency of 99% is possible in Energy Saver Application

Toroidal transformer is gaining more and more acceptance due to its unique features and advantages. In fact, because of its low weight & height, Toroidal transformer is being increasingly preferred over the conventional E&I transformer. In certain applications, low magnetic stray field & the low mechanical hum of Toroidal transformer are the most advantageous features. The low no load losses of the Torroidal transformer are of great value in 24 hours stand by equipment. The Toroidal transformer being custom built proves very economical in large production batches. Dual output voltages can be provided if desired. It is also possible to have primary suitable for 115Vor 230V AC, 50Hz.

A Thermal cut off can be incorporated in Toroidal transformer as a special feature at an extra cost. Our manufacturing experience of number of years has given us extensive knowledge & insight in designing the Radiotone Toroidal transformer. We use high quality material inputs in order to maintain the quality. The INSULATION between the primary & secondary winding is a fundamental safety feature, and to ensure this, we use only,BIS (Bureau of Indian Standards) approved insulating material. Special attention is given to insulation resistance, Hi-pot test & creepage distances.
