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