Product Overview
The Allen-Bradley 1606-XL480EPT is a single-phase switched-mode power supply from Rockwell Automation’s Bulletin 1606-XL standard series, built to deliver a regulated 24 V DC rail for PLCs, I/O modules, sensors, actuators, network switches and the general population of 24 V loads in an industrial control cabinet. Rated at 480 W with 20 A of continuous output current at 24 V, the Allen-Bradley 1606-XL480EPT is sized to carry a medium-to-large panel on its own, and its output can be trimmed across a 24 to 28 V DC range so the rail can be raised slightly to compensate for voltage drop on long cable runs to remote I/O.What separates this model from a basic panel supply is the feature set carried in the “EPT” designation: active power factor correction, remote shutdown signal terminals, and overload behaviour that can be configured for continuous current or hiccup mode. That last point matters more than it sounds — in continuous-current mode the Allen-Bradley 1606-XL480EPT keeps feeding well above rated current during a load start-up instead of switching off, which lets awkward loads such as DC-DC converters, solenoid banks and small motors start reliably and lets downstream protective devices trip selectively. It is also designed for parallel operation, so two units can share a load for redundancy or additional capacity.Input is 100–120 / 200–240 V AC with automatic selection at 47–63 Hz, so the same unit works on 120 V and 230 V grids without a tap or jumper. Cooling is by natural convection with no fan, and the Allen-Bradley 1606-XL480EPT carries worldwide industrial approvals, making it a straightforward choice for machine builders shipping globally and for maintenance teams replacing like-for-like in existing panels.
