Product Description
Product Overview
The Signal Transformer LT Series offers compact Safety Extra Low Voltage (SELV) output lighting transformers 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 convert 120V or 277V to 12V, providing a safer work environment by eliminating potential shock hazards through SELV isolation. 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. Custom versions are available upon request.
