Allen-Bradley 1606-XLS480E-3 Industrial Power Supply
The Allen-Bradley 1606-XLS480E-3, also cataloged as the 1606-XLS480E-3 Power Supply, operates as a dedicated hardware component for converting three-phase AC input into regulated 24-28 VDC power delivery within industrial control panels and automation networks. It directly feeds PLC racks, field actuators, and control electronics while delivering a 480 W rated output with 150% power boost capability to absorb transient inductive load spikes.

Firmware Flash Compatibility and I/O Density Scaling
Engineered for seamless integration alongside high-density control chassis, the unit ensures deterministic power stability across backplane bus communication networks. The ultra-high efficiency rating of 95% reduces cabinet thermal loading, preventing voltage sag during peak system operations or firmware flash execution across adjacent I/O modules. Integrated current sharing allows parallel operation configurations to scale overall power capacity or establish N+1 redundancy across high-availability automation racks.
Frequently Asked Questions
Q: How does the 1606-XLS480E-3 accommodate high-inrush field loads?
A: The power supply provides a 150% peak power boost capability, allowing it to deliver short-term extra current without dropping output voltage when driving heavy inductive loads like field relays, DC motors, or solenoids.
Q: Can multiple 1606-XLS480E-3 units be connected in parallel for redundant operation?
A: Yes, the module supports parallel operation mode. When installed with appropriate decoupling diodes, multiple units can be wired together to build N+1 redundant power supply topologies or increase total load output.
Field Installation Guidelines
- Mount the power supply vertically on a standard 35 mm DIN rail inside a ventilated electrical control cabinet.
- Ensure minimum clearance distances (typically 40 mm top, 20 mm bottom, and 5 mm lateral) around the perforated housing to facilitate natural thermal convection.
- Wire the three-phase AC mains (380 to 480 VAC) to the primary terminal block with proper phase rotation and earth grounding.
- Adjust the front-panel potentiometer to set the target DC output voltage (24 to 28 VDC) prior to connecting active control loads.
- Utilize properly sized copper conductors and strain-relief cable management to prevent terminal connection stress.
