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.
