Allen-Bradley 1606-XL120D 1606-XL Series Industrial Switched Mode Power Supply

Product Overview

The 1606-XL120D functions as a foundational power conversion component within the 1606-XL series. This 120-Watt switched-mode power supply (SMPS) converts universal AC line voltage into a stabilized 24V DC rail, powering essential automation hardware including PLCs, sensors, and human-machine interfaces. Although the manufacturer has officially discontinued this series, we provide 100% Brand New, original units to ensure your legacy control systems remain operational without the risks associated with used or refurbished surplus.

Technical Specifications

The 1606-XL120D utilizes a high-frequency switching architecture to maintain efficiency and minimize heat generation within control cabinets.

Engineering Advantages

• Universal Input Flexibility: The module accepts a broad input range of 100-240V AC. This eliminates the need for manual jumpers or voltage-selection switches, allowing for global deployment across different utility standards.

• Rapid DIN Rail Integration: The integrated metal mounting clip snaps securely onto any standard 35mm DIN rail. This reduces installation time and ensures the unit remains stable even in high-vibration machinery environments.

• Advanced Surge Suppression: Internal filtering circuits dampen voltage spikes and line noise. This provides a "clean" DC output that prevents logic errors or communication drops in sensitive PLC backplanes and analog I/O modules.

• Optimized Thermal Convection: The chassis design promotes natural airflow. By maintaining a narrow profile, the 1606-XL120D maximizes panel space while preventing the overheating of adjacent modules.

FAQs

• Can the 1606-XL120D handle inductive loads like solenoids?

  Yes. The unit features robust overload protection and handles the initial inrush currents typical of solenoids and small DC motors without triggering a shutdown.

• What is the benefit of buying "Brand New" for a discontinued model?

  Power supplies contain electrolytic capacitors that degrade over time, especially when used. Our 100% Brand New stock ensures these capacitors possess their full service life, preventing the "ripple voltage" issues common in older, used units.

• Does this power supply require a cooling fan?

  No. The 1606-XL120D relies on natural convection. Ensure you leave standard clearance (typically 15-20mm) above and below the unit to allow for proper heat dissipation.

• How do I adjust the output voltage?

  The front panel includes a small potentiometer that allows you to fine-tune the output voltage slightly (typically 24-28V DC) to compensate for voltage drops over long cable runs
