Allen-Bradley NSB 1497-N2 Control Transformer

Allen-Bradley NSB 1497-N2 is a compact control circuit transformer rated at 0.075 kVA (75 VA) that steps down from a 240/480 VAC mains supply to a 110/120 VAC control power output. Built for industrial environments, this transformer powers relays, contactors, timers, PLC peripherals, and other control devices in panels and automation systems. As part of the 1497 family, the NSB 1497-N2 provides isolated, low-voltage power for control circuits derived from higher-voltage sources, helping simplify panel wiring and improve control reliability. Key specifications include a 0.075 kVA rating; primary voltage options of 240 VAC or 480 VAC; secondary voltage of 110/120 VAC. Typical applications include powering control circuits in conveyors, packaging lines, presses, and other machinery that require a dedicated low-voltage control power source from a 240/480 VAC supply.
