Allen-Bradley 1497-D-CXSX-0-N Control Transformer

The Allen-Bradley 1497-D-CXSX-0-N is a 200 VA control-circuit transformer designed to power industrial control devices from a higher-voltage supply. It uses a 600 V primary rated for 60 Hz (550 V at 50 Hz) and provides a 110 V secondary at 50 Hz or 120 V at 60 Hz, delivering up to 200 VA of usable power for relays, contactors, timers, and other control equipment. Its footprint is compact: about 4.5 inches wide, 4-7/8 inches deep, and 3-29/32 inches tall, with a shipping weight of roughly 8.4 lb (3.81 kg). The unit ships without fuse blocks and without a cover, configured as 0 primary–0 secondary fuse blocks, and when protection is added per NEC, secondary fuse size is 2.5 A at 120 V and primary fuse size 4 A at 240 V. An inrush rating of 754 VA is noted at 95% of rated primary voltage with a 40% power factor. Copper conductors are used in the winding, and this transformer is part of Allen-Bradley’s 1497 family of standard control transformers, intended for mounting in control panels where a reliable, locally sourced 110/120 VAC supply is required for control circuitry.
