Our advanced technology yields a very small footprint, reduces wasted power, and TWICE THE POWER IN HALF THE SP ACE offers the highest power density in its class. This efficient design means reduced energy Typical Mechanical Drawing: costs, a greater return on your investment, greater reliability and longer product life. Inches (millimeters), refer to XL280 Product Specification for complete information. .375 5.30 UNMATCHED POWER DENSITY (9.53) (134.6) With an overall height of 1.43" and a 3" x 5.3" 4.55 .225 (115.6) footprint, the XL280 Series boasts a power (5.71) density over 13 watts per cubic inch. It is ideally suited for OEMs using the industry Pin 1 Pin 1 J4 standard 1U chassis. J1 XL280 Series J2 3.00 2.55 HIGH EFFICIENCY IN A SMALL PACKAGE Height = 1.43 (36.3) (76.2) (64.8) The XL280 Series provides up to 90% Pin 1 Pin 1 efficiency. Our unique design reduces energy Safety ground connection point J3 at plated through hole consumption and generates less wasted heat. It requires little forced air cooling, decreases AC power consumption, increases reliability and economy of operation. Comparisons Lock washer Screws shown for reference only of efficiencies show that our supplies can reduce losses up to 50%. 1.43 1.18 0.06 0.19 (36.3) (30) (1.5) (4.8) COMPLETE PROTECTION The main output is enabled whenever all of the required startup conditions are met, Printed Circuit Board 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. Specifications are subject to change without notice. It is responsibility of each customer to thoroughly test each product and part number under their unique parameters and environments to ensure a product will work properly and reliably.
