Allen-Bradley 1606-XL480E-3W Performance Series 3-Phase Switched Mode Power Supply

Product Overview

The 1606-XL480E-3W operates as a heavy-duty, three-phase switched-mode power supply designed for high-demand industrial automation environments. It converts a wide-range 3-phase AC input into a stabilized 24V DC output, delivering 480 Watts of continuous power. This module serves as the primary energy source for PLC racks, HMI panels, and field-side actuators in complex control systems. Although the manufacturer officially discontinued this series, we supply 100% Brand New, original factory units to help you maintain existing infrastructure without the complexity of re-engineering your power distribution layout.

Technical Specifications

This unit optimizes electrical conversion efficiency while maintaining a robust thermal profile for cabinet installation.

Engineering Advantages

• Three-Phase Load Balancing: The 3-phase input design significantly reduces the current draw per phase compared to single-phase units. This prevents phase imbalance in your facility's power grid and allows for smaller wire gauges and protective circuit breakers.

• High Inrush Handling: The 1606-XL480E-3W handles high startup currents effectively. It ensures that large inductive loads, such as solenoids or DC motors, do not trigger nuisance trips or voltage sags during initial activation.

• Efficient Space Management: Despite its 480W output, the module maintains a compact form factor. The integrated DIN rail clip facilitates rapid installation in crowded enclosures, while the vertical orientation promotes natural convection cooling.

• Industrial Grade Filtering: Internal circuitry suppresses electromagnetic interference (EMI) and line noise. This provides "clean" DC power to sensitive electronics, such as analog I/O modules and communication adapters, preventing data corruption in high-interference zones.

FAQs

• Can the 1606-XL480E-3W operate on a single-phase input?

  No. This specific model requires a 3-phase input (400-500VAC) to operate correctly. Attempting to run the unit on single-phase power will likely result in under-voltage faults or internal component stress.

• Is this unit compatible with the newer 1606-XLS series?

  While the 1606-XLS series serves as the modern functional successor, the 1606-XL480E-3W possesses specific physical dimensions and terminal locations. Replacing it with a newer model may require DIN rail adjustment or rewiring; hence, using a Brand New original unit simplifies direct maintenance.

• What is the significance of the "3W" suffix?

  The "3W" denotes the 3-phase wide-range input capability. It ensures the power supply maintains a steady 24VDC output even if the supply voltage fluctuates within the 400-500VAC window.

• Does this unit support parallel operation for increased current?

  You should check the specific revision for decoupling requirements. Typically, these units require external diode modules (such as the 1606-XLSRED) if you intend to link multiple power supplies for redundancy or higher amperage.
