The Signal Transformer LT Series (Lighting Transformer) offers Safety Extra Low Voltage (SELV) outputs, designed for OEM installations in landscape, track, recessed, and LED lighting, as well as security systems across commercial, consumer, and industrial sectors. These step-down transformers are essential for converting 120V or 277V to 12V when SELV outputs are required for control equipment and other electronic devices. The LT Transformer Series provides SELV isolation, eliminating potential shock hazards and contributing to a safer work environment. The LT277-50-12 is suitable for 480V, 3-phase 4-wire systems, while the LT120-50-12 is designed for single-phase 120V supplies.
