ULTRA SMALL, HIGH EFFICIENCY POWER SUPPLIES XL280 AC-DC Series 280 W AC-DC /3 X 5.3 FOOTPRINT AVAILABLE MODELS: 12V 56V UP TO 90% EFFICIENCY HIGH POWER DENSITY: 3 OVER 13 W/in ALL OUTPUTS MAY BE PARALLELED REMOTE ON /OFF 5V STANDBY OUTPUT (1A) 12V AUX OUTPUT (1A) UNIVERSAL AC INPUT ACTIVE PFC (90 264 VAC) ACTIVE CURRENT SHARING FOR N, N+1 ACTIVE INRUSH CURRENT PROTECTION RoHS COMPLIANT POWER SUPPLY DESIGN LEADER 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 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 information375 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.ULTRA SMALL, HIGH EFFICIENCY POWER SUPPLIES XL280 AC-DC Series PART REGULATION MAXIMUM RIPPLE& MODEL OUTPUT VOLTAGE NUMBER (%) CURRENT (A) NOISE (P-P) V1 12 3 23.3 120 mV XL280-12 400082-01-2 V2 12 5 5.0 120 mV XL280-12 CS 400081-01-4 V3 12 5 1.0 120 mV V4 5sb 5 1.0 50 mV V1 24 3 11.7 240 mV XL280-24 400082-02-0 V2 12 5 5.0 120 mV XL280-24 CS 400081-02-2 V3 12 5 1.0 120 mV V4 5sb 5 1.0 50 mV V1 48 3 5.8 480 mV XL280-48 400082-03-4 V2 12 5 5.0 120 mV XL280-48 CS 400081-03-0 V3 12 5 1.0 120 mV V4 5sb 5 1.0 50 mV V1 54 3 5.2 540 mV XL280-54 400082-04-6 V2 12 5 5.0 120 mV XL280-54 CS 400081-04-8 V3 12 5 1.0 120 mV V4 5sb 5 1.0 50 mV V1 56 3 5.0 560 mV XL280-56 400082-05-3 V2 12 5 5.0 120 mV XL280-56 CS 400081-05-5 V3 12 5 1.0 120 mV V4 5sb 5 1.0 50 mV CS = Current Sharing INPUT SPECIFICATIONS OUTPUT SPECIFICATIONS OPERATING SPECIFICATIONS Nominal Input Voltage: 100 240 VAC Total Output: 280 W Operating Temperature: 25 C to +50 C Tested Input Limits: 90 264 VAC Hold-up Time: Minimum 22 mS Temperature Derating: 2.5% / degree 50 C to 70 C Input Frequency Range: 47 63 Hz Efficiency: Up to 90% Storage Temperature: 40 C to +85 C Input Current: 3.5 A 100 VAC Minimum Load: No load Forced Air Cooling: 10 CFM minimum Input Protection: 5 A fuse Over / Under Shoot: Maximum 10% at turn-on Convection Cooling: See Specification Safety Isolation: 3000 VAC input to output Output Isolation: For POE 1500 VAC input to ground MTBF: 546,464 hours 25 C* PROTECTION Inrush Current: 14 A 240 VAC SIGNALS Overvoltage Protection: V1 (latches off) Power Factor Active PFC circuitry, meets Remote Sense: V1 and Return Overpower Protection: Protected / Auto Recovery Correction: or exceeds EN61000-3-2 Current Sharing: V1 using active circuitry Short Circuit Protection: Auto recovery of Leakage Current: 0.75mA 240 VAC / 60 Hz all outputs Passive Redundancy: V2 and V3 outputs may be wire OR-ed Thermal Shutdown: Auto recovery protection against over temperature Power Good (PG) Output: High-true CMOS logic conditions Remote Enable Input: Low-true input enables V1, V2, V3 output See Product Specification Some Models * See MTBF Report for additional temperature values 1 Compliance: USA/Canada: Europe: International: Safety: Underwriters Laboratories: UL 60950-1:2007 (2nd Edition) / 2006/95/EC - Low Voltage (Safety) Directive IEC 60950-1:2005 (2nd Edition) Safety of Information Technology C22.2 No. 60950-1-07 Safety of Information Technology Demko: EN 60950-1:2006+A11:2009 Equipment nd Equipment (ITE) (2 Edition) EMC: FCC part 15, subpart B 2004/108/EC Electromagnetic Compatibility (EMC) Directive IEC 61204-3 Class B EN 61204-3 Class B 1 See Product Specification for additional information For complete specifications on all models, please visit our website at: www.N2Power.com Every effort has been made to keep the information Qualstar and the Qualstar logo are registered Tel: 805-583-7744 E-mail: sales N2Power.com contained in this document current and accurate as trademarks of Qualstar Corporation.
