Allen-Bradley 1606-XLS240EC 240W Power Supply
Product Introduction
The 1606-XLS240EC belongs to the Allen-Bradley Bulletin 1606-XL performance power supply family. This conformal-coated version delivers a nominal 24V DC output at 240W rated power. Engineers choose it for control cabinets exposed to moisture, dust, and corrosive agents.
Conformal coating protects the internal circuitry from harsh conditions. Additionally, a 50% power reserve supports startup loads and brief overloads. The unit carries UL 60950-1, cUL, and CE approvals for global deployment.
Technical Specifications
The 1606-XLS240EC accepts wide input ranges for flexible installation. Specifically, AC input spans 100...240V nominal, while DC input covers 110...300V on this coated version.
Output voltage is 24V DC nominal and adjusts from 24...28V. Output current reaches 10A nominal, derating to 9A across the range. Meanwhile, typical efficiency sits at 93.5%, which reduces heat buildup inside enclosures.
Ripple and noise stay below 50mV maximum (mVpp). This clean output protects sensitive controllers and sensors. The DC OK relay contact provides status feedback to monitoring systems, and spring terminals simplify wiring during commissioning.
No communication ports exist on this unit. Therefore, it serves purely as a power conversion device without protocol support.
Mechanical and Environmental Parameters
Dimensions measure 60 × 124 × 117 mm (W×H×D). The compact housing fits standard DIN rail layouts, and the unit weighs approximately 900 g without packaging.
Operating temperature ranges from -25 to +70°C. Storage temperature spans -40 to +85°C for non-operating periods. Besides thermal tolerance, relative humidity reaches 5 to 95% non-condensing. The IP20 protection rating suits enclosed cabinet mounting only.
Installation Guide
First, verify the DIN rail is clean and securely fastened inside the cabinet. Next, snap the 1606-XLS240EC onto the rail until the latch clicks. Then connect input wiring to the spring terminals per the terminal diagram.
After wiring, set the output voltage using the front adjustment potentiometer. Specifically, turn the screw until a meter reads the target value between 24V and 28V. Finally, connect the DC OK relay to your monitoring circuit if needed.
Ensure adequate ventilation around the unit. Moreover, keep clearance above and below the housing for convection cooling. The conformal coating does not permit immersion or washdown cleaning.

FAQ
Q1: What makes the 1606-XLS240EC different from standard 1606-XLS units?
A: This version adds conformal coating to the PCB. Therefore, it resists moisture, dust, and corrosive gases better than uncoated models.
Q2: Can the 1606-XLS240EC accept DC input?
A: Yes. It supports DC input from 110V to 300V. This flexibility suits battery-backed systems and DC bus applications.
Q3: How does the 50% power reserve help my application?
A: The reserve supplies up to 15A briefly during motor startup. Consequently, nuisance trips decrease when inductive loads energize.
Q4: What is the purpose of the DC OK relay contact?
A: The relay signals output status to PLCs or alarm panels. Specifically, it closes when output voltage stays within tolerance.
Q5: Does this power supply include communication ports?
A: No. The 1606-XLS240EC has no communication interface. It operates as a standalone power conversion unit without protocol support.
