Application Scenarios
A food processing plant in the Midwest operated three production lines powered by legacy Allen-Bradley control systems. When the plant’s power infrastructure experienced recurring voltage sags during peak summer demand, the 1606-XL240E power supplies in each control cabinet demonstrated their value by maintaining stable 24 VDC output through input voltage fluctuations that would have caused lesser supplies to drop out. The front-panel potentiometer preset at 24.5 V provided consistent power to PLC racks and I/O modules, while the green LED status indicators gave maintenance technicians immediate visual confirmation of supply health during routine inspections.

Technical Principles and Innovative Values
Innovation Point 1: PowerBoost Function for High-Inrush Loads. The 1606-XL240E delivers a 20% power boost up to 288 W, providing 12 A of short-term output current at temperatures up to 45°C. This capability eliminates the need to oversize the power supply when starting loads with high inrush currents, such as DC motors, contactor coils, or capacitive loads in I/O modules. The supply delivers this reserve power without switching off or entering hiccup mode, maintaining stable output voltage as current demands temporarily spike.
Innovation Point 2: Flexible Parallel Operation for Redundancy. The 1606-XL240E supports up to five parallel operations when configured in Parallel Mode via an onboard jumper. This architecture enables N+1 redundancy configurations where a single supply failure does not interrupt DC power to critical loads. The parallel mode also allows load sharing across multiple units, extending the operational life of each supply by distributing thermal stress and reducing the current burden on individual modules.
Innovation Point 3: Long-Life Capacitor Design for Extended Service. The 1606-XL240E exclusively uses electrolytic capacitors rated for 105°C, compared to the 85°C rating common in standard-grade power supplies. This higher temperature rating directly translates to longer operational life, as capacitor degradation is the primary failure mode in switched-mode power supplies. Combined with an MTBF exceeding 425,000 hours, the 1606-XL240E delivers reliable performance in continuous-duty industrial applications where power supply replacement is disruptive.
Innovation Point 4: Wide Input Voltage Range with Auto-Select. The 1606-XL240E accepts a broad input range of 85-264 VAC, making it suitable for global installations without hardware modification. The unit handles both 100-120 VAC and 200-240 VAC nominal inputs through automatic selection, eliminating the risk of incorrect voltage setting during commissioning. A DC input option of 240-375 V is also available for battery-backed or DC-powered systems.
