Allen-Bradley 1497-D-BASX-3-N Transformer

The Allen-Bradley 1497-D-BASX-3-N is a 200 VA control-circuit transformer that accepts 240/480 V (60 Hz) or 220/440 V (50 Hz) on the primary and provides 110 V (50 Hz) or 120 V (60 Hz) on the secondary for control circuits in industrial equipment. It includes two primary fuse blocks and one secondary fuse block, with primary fusing of 4 A at 240 V (per NEC) and secondary fuse of 2.5 A at 120 V. Copper-windings construction and dimensions of 4.5 in wide by 3-29/32 in high by 4-7/8 in deep, with an approximate weight of 8.4 lb, keep the unit compact for integration into control panels. Cataloged in Rockwell Automation’s 1497 Control Circuit Transformer family, this model is used to power relays, timers, and other control logic components in PLC-based systems while delivering reliable, low-voltage power from higher-voltage mains.
