     Standard Design Low Voltage Lamp Transformers

Our standard design toroidal lamp transformers are available for 12 or 24 volt, 60Hz halogen lighting systems from 50VA to 1000VA. The transformers are available either bare with a standard mounting kit or supplied mounted inside  steel enclosures for remote surface or recessed installation. The transformers have built-in auto-resettable thermal protection.

The longevity of a toroidal transformer operating within specified load is far superior to an electronic transformer due to its simplistic construction, and also incorporating steel, copper and polyester as its basic components
