Products

High level of consistency in our Toroidal Transformer offer many advantages over a conventional laminated transformer. Toroidal Transformer, by meeting today's requirements for smaller, more efficient, quieter and safer products, are being accepted in an increasing range of electronic and electrical equipment. With toroidal transformer smaller dimensions, lighter weight and low stray magnetic fields, you can build more compact, lower cost quality products without sacrificing the cost. From 5 VA to 10 KVA – 3 Phase.
CE /UL/ RoHS we also have other products like halogen transformers, voltage controllers, SMPS, stabilizers and other transformers has enabled us to shine even in the discerning export market. Adherence to cost effective techniques of production enables us to offer international standard CE EN 60742 approved products. We have continuously sharpened our abilities to be able to serve our clients and satisfying them with our international quality products.

Halogen Transformer

We develop standard halogen transformers for 1, 2, 3. It produces low noise and least leakage flux. These transformers can be supplied in bulk quantity within a short time frame.

Benefits of Toroidal Halogen Transformer
  • The Toroidal is Smaller, Lighter & Thinner than E-I Transformer.
  • Produces no noise, a feature far better than E-I Transformer.
  • Produces Least Leakage flux than E-I Type.
  • Least heat because of the shape, the cooling surface area is more than others.
  • Bobbin less design leads to slimline structure.
  • Excellent Performance than E-I, R-Core Transformer.
  • Easy one bolt mounting arrangements.
