Description

The 1606-XLS960E-3 is an Allen-Bradley (Rockwell Automation) Performance family switched mode power supply delivering 960W of output power at 24VDC nominal (adjustable 24–28VDC) with a 40A rated output current. Designed for three-phase 380–480VAC input, this compact DIN-rail mountable unit is engineered for demanding industrial automation applications requiring reliable, high-efficiency DC power.

The 1606-XLS960E-3 features 95.3% typical efficiency, active power factor correction, and a 150% power boost capability that supports starting heavy or capacitive loads without requiring a larger power supply. With Class 1 Division 2 and marine certifications (ABS/GL/RINA), it is suitable for harsh environments including hazardous locations and shipboard installations.

Application Scenarios

In a large automotive assembly plant, a new robotic welding cell required a robust 24VDC power source for its PLC rack, I/O modules, safety relays, and servo drive control circuits. The existing single-phase power supplies were insufficient—the combined load exceeded 30A continuous, and the servo drives demanded a significant inrush current during acceleration. The engineering team selected the 1606-XLS960E-3 for its 40A rated output and 150% power boost capability, which provides 60A for up to 4 seconds to handle the servo drive startup without voltage sag.

Mounted on DIN rail within the control cabinet, the 1606-XLS960E-3‘s compact 110mm width conserved valuable panel space. The DC OK relay contact was wired to the PLC’s diagnostic input, providing immediate notification of any power supply fault. After 18 months of continuous three-shift operation, the power supply maintained stable 24VDC output with no production downtime attributable to power-related issues.
