Allen-Bradley 1606-XLS960E-3 Switched Mode PSU | High Power

Technical Specifications

Main Features and Advantages

High Efficiency and Power Density: The Allen-Bradley 1606-XLS960E-3​ utilizes advanced switched-mode technology to achieve high conversion efficiency, typically exceeding 93%. This high efficiency minimizes heat generation within the control panel, reducing cooling requirements and contributing to significant energy savings over the unit’s operational life. The fanless, convection-cooled design eliminates a common point of failure (the fan), ensuring silent operation and enhanced reliability, particularly in dusty environments. Despite its high 960-watt output, the unit maintains a compact form factor, offering excellent power density that saves valuable space on the DIN rail, allowing for more components in the same enclosure.Robust Design and Comprehensive Diagnostics: Built for industrial durability, the 1606-XLS960E-3​ features a wide-range input (85-264 VAC) that automatically adapts to global mains voltages, simplifying inventory and deployment. It includes full protective circuitry for overload, short circuit, and overtemperature conditions, allowing it to withstand harsh electrical environments and safely shut down if necessary. A key diagnostic advantage is its integrated signaling contact—a relay that changes state to indicate a fault condition (e.g., loss of output) or a “DC OK” status. This allows for remote monitoring and integration into the control system’s alarm logic, enabling predictive maintenance. The high power factor (>0.95) reduces harmonic feedback to the AC line, making the Allen-Bradley 1606-XLS960E-3​ a good citizen on the plant electrical network and helping facilities meet power quality standards.

Application Field

The Allen-Bradley 1606-XLS960E-3​ is the ideal power source for large or distributed control systems requiring a substantial and clean 24VDC power bus. In Factory Automation, it is commonly used as the central power supply for entire machine control panels or production lines, powering multiple PLCs (like ControlLogix or CompactLogix racks), extensive I/O islands, motor starter coils, network switches, and HMI terminals. Its 40-amp capacity makes it suitable for applications with many solenoid valves, pneumatic actuators, or distributed I/O blocks. Within Process Industries​ like Chemical, Oil & Gas, and Water Treatment, the 1606-XLS960E-3​ provides reliable power for critical safety instrumented system (SIS) components, analyzer shelters, and remote terminal units (RTUs), where its robust design and diagnostic capabilities are essential for maintaining uptime.For Material Handling Systems, such as large conveyor networks, automated storage and retrieval systems (AS/RS), and packaging lines, this power supply can handle the inrush currents from numerous motors and sensors. Its ATEX/IECEx certification for Zone 2 hazardous locations makes the Allen-Bradley 1606-XLS960E-3​ suitable for use in areas where flammable gases or dust may be present, such as in mining, grain handling, or petrochemical plants. It is also extensively used in Infrastructure Projects​ for building management systems (BMS), traffic control systems, and powering telecommunications equipment in industrial settings, where a single, high-capacity, and fault-tolerant DC source is required to ensure continuous operation.
