Variable Transformers

POWERSTAT® Variable Transformers

Rugged, and designed for heavy-duty use, POWERSTAT® Variable Transformers provide excellent power regulation with negligible variation in output voltage from no-load to full-load current. They provide a simple, rugged method of controlling electrical voltage, current and power. They take in utility line voltage and provide continuously adjustable output voltage. Available in both manual and motor-driven options, they offer high current ratings, long life, superior overload capacity and exception resistance to contaminants such as fungus and salt spray. Learn more

Volt-Pac® Variable Transformers

Volt-Pac® variable transformers provide continuously adjustable voltage to an electrical load from a fixed line voltage. Operation is based on autotransformer action in unsaturated magnetic components, so the output waveform is a precise reproduction of the input waveform. Learn more

Lighting Controls

LUXTROL® Incandescent Light Control Equipment

LUXTROL® Incandescent Light Controls are extensively used for incandescent lighting in residential, theatrical, institutional, commercial and industrial installations. All dimmers are continuously adjustable transformers that regulate light intensity by controlling the voltage applied to the lamps. Moving the dimmer control knob or actuating the drive motor moves a brush-contact over a bared portion of the transformer winding producing any desired lighting intensity from complete darkness to full brightness. Learn more
