Products We manufacture

AC Voltage and Toroidal Transformers
Transformers work by using electromagnetic induction to transfer energy between two coils in an AC circuit. A toroidal transformer steps power up or down based on magnetic fields passing through the secondary coil

Common mode Chokes, Magnetic Ring Inductance Transformers
Common mode chokes are electrical filters that block high-frequency noise while allowing desired signals to pass through. Magnetic ring, UU filter, R rod inductance, high and low frequency transformers.

3-Phase Isolation transformers
Isolating transformers help protect people and equipment by providing complete electrical isolation between the two circuits. This helps prevent electric shocks and other hazards and provides extra protection against potential power surges.
