Product Overview

The Allen-Bradley 1606-XLS120EA serves as a premium, high-efficiency switched-mode power supply within the specialized 1606-XLS Extra Life Performance Series. This single-phase module converts variable global mains electricity into a highly stabilized 24V DC output, delivering a continuous 5 Amperes to power sensitive industrial controllers, human-machine interfaces (HMIs), field sensors, and actuator loops. An adjustable faceplate potentiometer permits fine-tuning of the output voltage up to 28V DC to compensate for line voltage drops across extended wire runs. Featuring an ultra-slim footprint and active power factor correction, this active lifecycle module optimizes cabinet space while filtering out dirty electrical harmonics. We stock and distribute this component exclusively as a 100% brand new, original factory-packaged item to ensure absolute reliability and long operational life inside modern automated control systems.

The following engineering matrix sets out the precise electrical limits, thermal metrics, and international certification standards for the 1606-XLS120EA power supply:

Engineering Advantages

• Cabinet-Saving Slim Silhouette: The 32 mm physical width footprint reduces required DIN-rail horizontal real estate within high-density electrical enclosures. This compact layout allows panel builders to downsize control boxes or squeeze extra logic modules into tight retrofitted spaces.

• Active Harmonic Suppression & Global Input: An active power factor correction (PFC) network shapes the input current wave to yield a high 0.91 power factor. This circuit complies fully with EN61000-3-2 regulations and permits global deployment across varying nominal grids from 100V AC to 240V AC without input selector switches.

• High Transient Reserve Power (BonusPower): The power engine delivers up to 7.5 Amperes of reserve current at 24V DC to handle sudden inductive inrush spikes. This buffer allows the supply to start heavy DC motors, massive capacitive loads, and large magnetic solenoid valves without experiencing voltage sags or triggering premature overload shutdowns.

• Comprehensive Quad-Layer Electronic Safety Shields: Integrated electronic watchdogs continuously track output health. The module applies rapid automatic shutdown and restart sequences during short circuits, output overvoltage spikes, sustained overloads, and high-temperature thermal runaways to protect downstream PLC processors.

• Extensive Mains Interruption Buffering: The massive internal capacitor storage bank provides an exceptional holdup time ranging up to 59 milliseconds. This retention capability bridges brief line dropouts and macro-second utility grid switchovers, keeping your automation logic running without causing system resets.

FAQs

• Can I mount the 1606-XLS120EA in any physical orientation on the DIN-rail?

  No. To maintain optimal thermal performance, you must mount the 1606-XLS120EA vertically on a standard horizontal 35 mm DIN-rail, ensuring the input terminals face downward. Because the module relies entirely on natural air convection cooling instead of moving fans, you must maintain a 40 mm clearing zone above and a 20 mm clearing zone below the housing to facilitate unrestricted airflow.

• What does the integrated "DC OK" relay contact do inside the control loop?

  The "DC OK" contact functions as an isolated, hardware-driven dry relay output that monitors the actual voltage output status. The contact stays closed when the output remains above 22V DC; it opens immediately if the level drops below this threshold, allowing your supervisor PLC to detect power failures instantly and initiate safe emergency tool shutdowns.

• How does the unit behave when ambient control panel temperatures exceed 60 degrees C?

  The 1606-XLS120EA operates with zero performance degradation from -25 up to +60 degrees C. When ambient internal enclosure temperatures climb above +60 degrees C, you must apply a continuous output power derating scale of 3 Watts per degree C up to the absolute +70 degrees C operating limit to prevent internal thermal safety circuits from tripping.
