Allen-Bradley 1497-N43 Control Transformer

Allen-Bradley 1497-N43 is a 2 kVA, single-phase control transformer from the 1497 family that provides low-voltage control power from a higher-voltage supply. It features dual primary windings configured for 240/480 V input and a 120 V secondary output, making it suitable for powering relays, contactors, timers, PLC I/O modules, and other control devices in industrial panels. Operable on 50/60 Hz, this N43 variant is designed to be paired with standard industrial mains and control circuitry, delivering isolated 120 V for safe, reliable operation in manufacturing lines, material handling, presses, and packaging equipment. The 1497 line is known for rugged, dependable performance in harsh factory environments, and the N43 is the right choice when a proven solution is needed to convert 240/480 V mains to 120 V control power. When wiring, connect the primaries to your available supply (parallel for 240 V or series for 480 V) and use the secondary to feed your control circuit devices, keeping in mind typical control loads and device ratings. This model represents Allen-Bradley’s established approach to providing consistent, factory-standard control power with the reliability associated with the 1497 product line.
