LT277-50-12

Lighting Transformer (LT Series) 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 120V or 277V to 12V. Offering a safer work environment, the SELV isolation provided by Signal’s LT Transformer Series eliminates potential shock hazards. The LT277-50-12 is ideal for 480V, 3 phase 4-wire systems, where line voltage to neutral is equal to single phase 277V 50/60 Hz. The LT120-50-12 is designed for single phase 120V 50/60 Hz supplies.
