1606-XLE480EP Switched Mode Power Supply | Allen-Bradley

Configured for power conversion in industrial control systems, the Allen-Bradley 1606-XLE480EP (1606-XLE480EP Power Supply Module) provides direct physical/electrical execution. This single-phase hardware unit converts 100-240 VAC mains input to a regulated 24-28 VDC output, supporting a power delivery capacity of 480 W under nominal thermal conditions.

Hardware Specifications

Industrial Control and Drives Technical Characteristics

The 1606-XLE480EP employs high-frequency switching topology to maintain a 94 percent efficiency rating, minimizing thermal dissipation within the enclosure. The module supports a power factor of up to 0.99 and provides a typical hold-up time of 26 ms during mains voltage interruptions. I/O density scaling and system load management must account for the specific output current derating profiles: 20 A at 24 VDC (ambient < 45 deg C) or 24 A peak (ambient < 45 deg C). Users must ensure firmware flash compatibility or electronic diagnostic integration via the secondary communication ports if utilizing the power supply within a managed control network.

Frequently Asked Questions

Q: Does the 1606-XLE480EP support parallel connection for increased power?

A: Yes, these units can be connected in parallel to increase total current capacity, provided the installation follows the specific load-sharing and cabling requirements defined in the hardware manual to prevent output voltage instability.

Q: Is the output voltage adjustable?

A: Yes. The output voltage is adjustable via an integrated potentiometer within the 24-28 VDC range to compensate for voltage drop across long cable runs.

Field Installation Guidelines

• DIN-Rail Mounting: Secure the module to a 35 mm DIN rail. Ensure there is at least 40 mm of clearance above and below the unit to allow for natural convection cooling.
• Input Wiring: Connect the AC mains to the L and N terminals. Ensure that the input source is protected by an appropriately rated branch circuit breaker or fuse as specified by local electrical codes.
• Grounding: The PE (Protective Earth) terminal must be connected to a low-impedance earth ground. This is required for safety compliance and to minimize common-mode electromagnetic interference.
• Thermal Management: While the unit is designed for operation up to 70 deg C, derating is required for temperatures above 45 deg C. Ensure the enclosure provides adequate air circulation to prevent internal component fatigue.
