Allen-Bradley 1606-XL480E-3 NSNBC01 is a 480 W switched-mode power supply in the 1606-XL family that converts 3‑phase AC input into a stable 24–28 VDC output for industrial control systems. It accepts 3‑phase 400–500 VAC input and can deliver up to 20 A at 24 V (18 A at 28 V), for a 480 W maximum output, with a hold-up time greater than 11 ms at 24 V/20 A. The unit measures 220 mm wide by 124 mm high by 102 mm deep, and supports selectable single or parallel operation via a jumper, with a PFC choke included in some configurations. This power supply is intended to power 24 VDC logic, PLC I/O, and field devices within Rockwell Automation control architectures.
