The compact LT transformer components offer safety extra low voltage (SELV) outputs designed for industries and OEM installations of landscape, track, recessed, and LED lighting, as well as security systems in the commercial, consumer, and industrial sectors. When SELV outputs are required to operate control equipment and other electronic devices, a step-down transformer is needed to convert from 120 V or 277 V to 12 V. Offering a safer work environment, the SELV isolation prevents potential shock hazards.
