Extra low voltage (ELV) tungsten halogen lighting requires the use of a transformer to reduce the voltage of mains electricity supply to 12V AC.

The electronic transformer is different from a toroidal transformer in that it uses an electronic inverter to convert mains frequency AC 50Hz into high frequency AC, between 10kHz and 100 kHz depending on the transformer. An internal magnetic transformer then reduces the output voltage to 12V AC at 10- 100 kHz.

The electronic transformers for extra low voltage tungsten halogen lighting are compatible with both leading edge and trailing edge dimmers.

A 50VA electronic transformer’s full load losses are approximately 4W.
A 50VA toroidal transformer’s full load losses are approximately 14W.
