N2POWER XL280 AC AC-DC SERIES ULTRA SMALL, HIGH-EFFICIENC EFFICIENCY POWER SUPPLY 280W AC-DC 3" x 5.3" footprint Up to 90% efficiency High power density: over 13W / cu in. All outputs may be paralleled Remote on/off 5V standby output (1A) 12V aux output (1A) Universal AC input Active PFC (90 - 264VAC) Active current sharing for N, N+1 Active inrush current protection RoHS compliant POE compliant (54V and 56V models) Power Supply Design Leader Complete Protection N2Power leads the power density race with its high efficiency XL280 Series AC -DC power supplies. Our advanced technology yields a very small footprint, reduces wasted power, and offers the highest power density in its class. This efficient design means reduced energy costs, a greater return on your investment, greater reliability and longer product life. The main output is enabled whenever all of the required startup conditions are met, and is shut down upon command, loss of input power or whenever excessive loads or temperatures are sensed. When AC input power is lost it provides the host system with advanced warning of an impending shutdown. Unmatched Power Density Typical Mechanical Drawing: Inches (millimeters), refer to XL280 Product Specification for complete information. With an overall height of 1.43" and a 3" x 5.3" footprint, the XL280 Series boasts a power density over 13 watts per cubic inch. It is ideally suited for OEMs using the industry standard 1U chassis. High Efficiency in a Small Package The XL280 Series provides up to 90% efficiency. Our unique design reduces energy consumption and generates less wasted heat. Itt requires little forced air cooling, decreases AC power consumption, increases reliability and economy of operation. Comparisons of efficiencies show that our supplies can reduce losses up to 50%.
