Signal Transformer / Bel SLT Isolated 277V / 120V Step-Down Transformers
Signal Transformer / Bel SLT Isolated 277V / 120V Step-Down Transformers allow installers to derive a fully isolated 120V source from a 277V line. These transformers have UL, CSA, VDE, and IEC approvals and meet Class F insulation system (+155°C) requirements. The touch-safe terminals (IP20 type) offer a screw/binding clamp for hard wiring as well as 3/16” and 1/4” fast-on connections. The SLT series offers power ratings of 300VA, 450VA, 600VA, and 1000VA. Ideal applications include power task lighting and service receptacles.
