1606-XLE120EN Essential Power Supply Technical Guide
Product Introduction
The 1606-XLE120EN is a switched-mode power supply from Allen-Bradley. It provides a stable 24V DC output with a 120W power rating. This unit accepts a 100-120V AC single-phase input. Engineers often select this model for its ultra-small footprint. It fits easily into tight panel spaces. Moreover, the 1606-XLE120EN belongs to the Essential family. It delivers core functionality without extra features. The device suits regional applications requiring 120V AC mains. It provides a cost-effective solution for basic power needs.
Core Value
Firstly, this power supply offers high efficiency. The typical efficiency reaches 90%. This design minimizes heat generation inside enclosures. Secondly, the 1606-XLE120EN provides a 20% power reserve. You can use this extra current continuously at temperatures up to 45°C. Thirdly, the compact width of only 32mm saves valuable DIN rail space. Furthermore, the unit includes an active power factor correction of 0.59. It also features a low inrush current of 45A. These traits ensure stable operation and reduce electrical stress. The 1606-XLE120EN is a practical choice for machine builders and panel integrators.
Technical Insights
The 1606-XLE120EN operates with a stabilized output voltage. You can adjust the output from 24V to 28V DC. This flexibility supports sensitive loads or compensates for voltage drops. Specifically, the unit delivers 5A at 24V under normal conditions. It provides a dynamic boost to 6A for short periods. The ripple and noise remain below 50mV. This clean power is crucial for analog sensors and control circuits. Besides, the device includes electronic protection against overload and short circuits. It also guards against over-voltage and over-temperature events. The operating temperature range spans from -10°C to +70°C. Derating starts above 60°C. Therefore, ensure proper ventilation in sealed enclosures.
Installation & Maintenance
Mount the 1606-XLE120EN on a standard DIN rail. Alternatively, use the optional wall mounting bracket. Connect the input wiring to the screw terminals. Use a fuse rated B-16A or C-10A for external protection. Keep a clearance of at least 15mm between adjacent power supplies. This spacing ensures adequate convection cooling. Route the DC output cables separately from high-voltage lines. This practice reduces electrical noise. Periodically check the screw terminals for tightness. Verify the DC-OK LED indicator during operation. A green LED confirms normal output voltage. If the LED is off, check the input voltage and the load. Do not use this unit to charge batteries. Select a different model for charging applications. Clean the ventilation slots with dry compressed air during scheduled maintenance.
