Product Overview
The 1606-XLS240E is an Allen-Bradley Bulletin 1606-XLS switched-mode power supply, manufactured by Rockwell Automation, designed for mounting on a standard DIN rail in industrial control panels. Its purpose is to convert a single-phase alternating-current mains supply into a regulated 24 VDC control voltage for PLCs, I/O modules, operator interfaces, sensors, contactor coils, relays and other automation devices. The 1606-XLS240E is therefore a primary power source for the control circuit, not a DC/DC converter, not a redundant module and not a battery charger.
The 1606-XLS240E has a continuous power rating of 240 W at 24 VDC, which corresponds to a 10 A output. The output voltage is adjustable from 24 to 28 VDC, allowing the supply to compensate for voltage drop in long 24 VDC wiring runs or to suit equipment with a higher nominal operating voltage. The wide-range AC input accepts 100–120 VAC and 200–240 VAC at 50/60 Hz with automatic range selection, so the same unit can be installed across a broad range of international supply voltages without manual voltage-range switching.
The 1606-XLS240E is positioned in the 1606-XLS family as a compact, high-efficiency switched-mode supply with built-in output-side performance features. Its NEC Class 2 output compliance makes it suitable for control circuits where power-source limitations are part of the installation design. The combination of efficiency, adjustable output, output current boost and remote-control capability makes the 1606-XLS240E a practical choice for control panels that must support demanding inrush and pulsed loads without moving to a much larger supply.
