Manufactured to Spec

Three-Phase Transformers

Three phase transformer with three coils sequentially connected.
Our three-phase transformers have three coils sequentially connected to match the incoming power and transform the voltage to the level you need.

Single-Phase Transformers

Single phase industrial control transformer featuring primary and secondary voltages.
Our single-phase transformers can be used to raise or lower the voltage from one side of a transformer to another.


Three phase autotransformer with a single winding.
Our autotransformers contain only one winding with a portion of the coil serving as both the primary and secondary winding. Available in three-phase and single-phase models.

Isolation Transformers

Isolation transformer featuring symmetrical insulated primary and secondary windings.
Available in three-phase and single-phase models, our isolation transformers feature symmetrical, insulated primary and secondary windings that are physically separated from each other.


You need an electrical transformer manufacturer to determine the right approach for your specific needs. And you need consistent delivery—defect-free custom transformers that get finished on time, every time.

Customized and on a Budget

High-Voltage Transformers

High voltage transformer designed to handle up to 6,000 volts.
Handling 500 volts to 6,000 volts, our high-voltage transformers are designed for metering and protection in high-voltage circuits where safety is an issue.

Ferroresonant Transformers

Ferroresonant transformer designed to produce a single regulated secondary voltage.
Our three-phase or single-phase ferroferroresonant transformers are manufactured to produce a single regulated output for a variety of primary inputs within a specified range.

Toroidal Transformers

Toroidal transformer designed to transfer electrical energy from one circuit to another.
Toroidal transformers are designed to transfer electrical energy from one circuit to another by changing the voltage. Perfect when you need several design configurations to choose from and reduced off-load power consumption.

Inductors, Chokes, Reactors and Coils

two inductors
Offered in a wide range of materials, shapes, sizes and mounting options, these magnetic devices are primarily designed to reduce line voltage without incurring significant loss of power.
