Standard Design Toroidal Lamp Transformers

    Click here to view our De-Buzzing Chokes

    Our standard line of toroidal transformers for 12 or 24 volt halogen lamps are available either bare or enclosed for remote installation. The longevity of a toroidal transformer operating within specified load is far superior to an electronic transformer due to simplistic construction, incorporating steel, copper and polyester as its basic components. Part of our basic components may include standard mounting hardware. Our toroidal transformers are compact, light and quiet, and ideally suited for low voltage halogen lighting systems. The transformers come with auto-resettable thermal protection, and are available off-the-shelf from 50VA to 1000VA.

        Transformers mounted inside a white steel enclosure with automatic
        circuit breakers for remote installation. Enclosed transformers are UL listed.
        Input voltage 120V/60Hz. Single output voltage 12V under 300W and
        dual 12V For extra safety we have added auto-resettable thermal
        cut-offs inside the transformers between the primary and secondary windings.
