Hammond Power Solutions SP50NJ - Transformer 277V to 120V (Seismic Compliant)

SP50NJ

Hammond Power Solutions SP50NJ is a single-phase core and coil transformer designed for industrial power conversion applications. This unit provides voltage transformation from 277V primary to 120V secondary with series connections and operates at 50/60Hz frequency. Constructed with copper windings, it features an 80°C temperature rise and 130°C insulation class, housed in a standard core and coil configuration with terminal block primary termination. The transformer meets OSHPD compliance and IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) for earthquake-prone installations. Typical applications include industrial control systems, lighting circuits, and equipment requiring reliable voltage conversion in commercial and manufacturing environments.
