Hammond Power Solutions FS250SR - Single Phase Transformer 208-416V Primary (Seismic Compliant)

FS250SR

Hammond Power Solutions FS250SR is a single-phase transformer designed for industrial power distribution applications. This unit features flexible voltage configurations with primary connections of 208x416V and secondary connections of 12x24V, operating at 50/60Hz frequency with copper windings rated for 95°C temperature rise and 130°C insulation class. The transformer is housed in a compact Type 1/IP20 enclosure measuring 4.3in/110mm(H) x 3.9in/100mm(W) x 6.6in/168mm(D) with Pantone 349C green finish and standard terminal block primary termination. It complies with seismic standards including OSHPD and IBC 2018 (Sds=2.0, z/h=1, lp=1.5), ensuring reliable performance in demanding environments. Typical applications include control circuits, lighting systems, and industrial machinery requiring precise voltage transformation. Key Features & Specifications
