Allen-Bradley X-343858 Industrial Transformer

The Allen-Bradley X-343858 is a 0.075 kVA (75 VA) single‑phase control power transformer built as a dry‑type unit for industrial panels, designed to take mains voltages in the 240/480 VAC range and provide a stable 120 VAC control output. Primary windings are rated for 240/480 VAC, and the secondary delivers 120 VAC to energize relays, contactors, pilot lights, and other control circuitry, making it a common fit in machine panels and automation cabinets. This transformer is frequently referenced in Rockwell Automation catalogs as the 1497‑N2 family, and is widely offered as a used or surplus replacement; typical weight is around 10 pounds, reflecting a compact, robust form factor suitable for panel mounting. Applications include powering control circuits in conveyors, presses, packaging lines, and various automated equipment where a reliable low-voltage supply is needed from a 240/480 VAC source.
