Product Description
Product Overview
The SLT Series Isolated 277 V / 120 V Step Down Transformers are designed for chassis mounting, enabling installers to derive a fully isolated 120 V source from a 277 V line. These transformers are ideal for powering task lighting and service receptacles. They offer secondary voltage taps at 115 V and 125 V for high/low line adjustment and feature touch-safe terminals with screw/binding clamp and Fast-On connections.
