? Round shape with no air gaps
? Uniform primary and secondary windings locked in the magnetic field makes these transformers very quiet and efficient.
? Compact designing, efficiency, quiet and safer
? Smaller dimensions, lighter weight, and low stray magnetic fields
We specialize in manufacturing of above products as per customer specifications.
Toroidal Transformers, 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 performance.
Toroidal has a round shape with no air gaps, and with the primary and secondary windings uniformly distributed around the core, locks in\" the magnetic field and makes the toroidal transformer very quiet and efficient. Toroidal transformers are built around a ring-shaped core, which, depending on operating frequency, is made from a long strip of silicon steel or permalloy wound into a coil, powdered iron, or ferrite core.
We make wide range of Toroids based on customer specifications. We provide center potted, plate mounted, clamp mounted and many other types of Toroids on customer specifications.
