Variable
Transformers

Used in a variety of applications, variable transformers are a type of autotransformer which can expel differing amounts of voltage from the same input voltage.

Toroidal
Transformers

Toroidal transformers are more compact and lightweight and frequently used for electronic applications to step up or down voltage.

High Vortage
Transformers

We manufacture high voltage transformers that are usually single phase transformers which convert voltages from one level to another.

Low Voltage
Transformers

Low voltage transformers change the voltage capacity typically from 120 volts to 12 or 24 volts. They are used for low voltage lighting.

Copper Strip
Windings

As ferrite transformers now offer higher frequency and current power supply, copper strip winding is used to ensure that there is enough copper in the winding window.
