Allen-Bradley 1606-XL720E-3 AC-DC Power Supply

The Allen-Bradley 1606-XL720E-3 is a 720 W DIN-rail mounted AC-DC power supply that converts three-phase 400–500 V AC into a regulated 24–28 V DC output. It delivers up to 30 A at 24 V (about 26 A at 28 V) for reliable power to industrial controls, PLCs, sensors, and actuators within control cabinets. The unit is part of the 1606-XL series and includes a power factor correction (PFC) choke to help improve efficiency, with XL-series efficiency generally cited in the 82–92% range. Typical operating configurations specify a three-phase input of 400–500 VAC and a wide DC input window for systems that may experience voltage variations, while the standard module is designed for panel mounting on a DIN rail in rugged industrial environments. A hallmark of the XL720E-3 is its compact, modular design intended to support scalable automation installations, enabling clean, centralized power distribution for 24–28 V DC devices and subsystems across machines and production lines. For environmental and electrical performance, the XL720E-3 is specified for a broad operating temperature range typical of XL-series modules, making it suitable for manufacturing floors, machine enclosures, and other demanding industrial applications where stable, high-current DC supply is critical.
