Technical Parameters & Selection Guide

Selection Criteria: Choose the 1606-XLE240E-3 when your facility operates on three-phase 480VAC distribution and requires 8-10A of 24VDC power. For lower current needs (5A or less), consider the 120W model. If your installation uses single-phase 480VAC, select the 1606-XLE240E variant instead. Calculate total load current including 20% safety margin for future expansion and inrush requirements.

Advanced Integration Features

Redundancy Configuration: Pair with the 1606-XLSRED redundancy module to create N+1 fault-tolerant power architectures. Two units operate in parallel with automatic load sharing and seamless failover, ensuring zero downtime during maintenance or component failure—essential for critical process control applications.

Remote Monitoring Capability: DC OK relay contact provides real-time status feedback to PLC or SCADA systems, enabling predictive maintenance alerts and automated shutdown sequences. Integrate with Allen-Bradley FactoryTalk View for centralized power system monitoring across multiple control cabinets.

Parallel Operation: Multiple units can be paralleled using external diode modules to scale output current beyond 10A for high-power applications. Supports distributed power architectures where multiple supplies feed different zones of large control systems.

Custom Voltage Adjustment: Output voltage trimmer allows field adjustment from 24-28VDC to compensate for voltage drop in long cable runs or match specific equipment requirements without replacing the entire unit.

Frequently Asked Questions

What is the difference between 1606-XLE240E-3 and the standard 1606-XLE240E model?
The "3" suffix indicates three-phase 480VAC input capability, whereas the standard model accepts single-phase 120-240VAC input. Three-phase versions offer better efficiency and lower input current draw, making them ideal for industrial facilities with 480VAC distribution infrastructure.

Can this power supply operate on 400VAC three-phase European systems?
Yes, the wide input range (342-528VAC) fully supports 400VAC ±10% three-phase systems common in European and Asian industrial installations. The unit automatically adapts to input voltage variations without manual adjustment or configuration changes.

How much clearance is required above and below the unit for proper cooling?
Maintain minimum 50mm (2 inches) clearance above and below the unit for adequate convection airflow. In high-ambient environments (>50°C), increase spacing to 75mm or consider forced-air cooling of the entire enclosure to maintain optimal performance.

Does the unit include built-in circuit protection or do I need external fusing?
While the power supply has internal overload and short-circuit protection, Allen-Bradley recommends installing external input fusing (2A slow-blow) per UL508A panel building standards. This provides additional protection for facility wiring and simplifies troubleshooting during fault conditions.

What is the typical MTBF rating for this power supply model?
Mean Time Between Failures exceeds 300,000 hours at 25°C ambient temperature and 50% load, translating to approximately 34 years of continuous operation under normal industrial conditions. MTBF decreases at higher temperatures and full-load operation but remains above 150,000 hours even at maximum ratings.

Can I use this to power non-Allen-Bradley control equipment?
Absolutely. The 24VDC output is compatible with any industrial equipment rated for 24VDC operation, including Siemens, Schneider Electric, Omron, and other manufacturer's PLCs, I/O modules, sensors, and actuators. Standard industrial voltage and current specifications ensure universal compatibility.
