ULTRA SMALL, HIGH EFFICIENCY POWER SUPPLIES XL275 AC-DC Series 275 W AC-DC/3 X 5 FOOTPRINT UP TO 91% EFFICIENCY HIGH POWER DENSITY: 3 OVER 12 W/in ALL OUTPUTS MAY BE PARALLELED REMOTE ON/OFF 5W 5V STANDBY SUPPLY UNIVERSAL AC INPUT ACTIVE PFC (90 264 VAC) BUILT IN OR-ING MOSFET FOR N, N+1 ACTIVE INRUSH CURRENT PROTECTION RoHS COMPLIANT PMBus INTERFACE FOR DIGITAL POWER MANAGEMENT (OPTIONAL) POWER SUPPLY DESIGN LEADER TM N2Power leads the power density race with its small, high efficiency XL275 Series AC-DC power supplies. Our advanced technology TWICE THE POWER IN HALF THE SP ACE yields a very small footprint, reduces wasted power, and offers the highest power density in Typical Mechanical Drawing: its class. This efficient design means reduced Inches (millimeters), connectors and pinouts may vary with model. energy costs, a greater return on your investment, greater reliability and longer product life. Refer to XL275 Product Specification for complete information225 5.00 ADVANCED DIGITAL CONTROLLER (5.7) (127.0) The XL275 is the first power supply in this 4.55 .225 (115.6) (5.7) class to use a dedicated digital microcontroller to supervise the units operation. The micro- controller monitors the following parameters: DC voltage on the bulk capacitor XL275 AC - DC 3.00 2.55 (supplied by the AC mains) Height = 1.5 (38.1) (76.2) (64.8) Output voltage Output current Auxiliary 12V output voltage Transformer temperature Ambient temperature Fan tachometer 1.50 The microcontroller enables the main (38.1) output whenever all of the required startup 0.75 (19.1) conditions are met, and shuts it down Screws shown for reference only upon command, loss of input power or whenever excessive loads or temperatures are sensed. It always provides advanced warning of an impending shutdown before output power is lost. XL275s to communicate over the same bus and current plus the ambient and transformer TM using the PMBus protocol. This interface temperatures and fan tachometer speed. PMBus OPTION allows routine remote control of the main Because it is programmable, the microcontroller TM An optional PMBus digital communications outputs and the 12V fans. The host can also code can be customized to meet unique interface is available to allow up to four query the microcontroller for its output voltage OEM requirements.ULTRA SMALL, HIGH EFFICIENCY POWER SUPPLIES XL275 AC-DC Series INPUT SPECIFICATIONS PART REGULATION MAXIMUM RIPPLE & MODEL OUTPUT VOLTAGE NUMBER (%) CURRENT (A) NOISE (P-P) Nominal Input Voltage: 100 240 VAC Tested Input Limits: 90 264 VAC V1 12 3 22.9 100 mV Input Frequency Range: 47 63 Hz XL275-12 400029-02-1 V2 12 5 1.0 80 mV Input Current: 3.5 A 100 VAC XL275-12 CS 400029-01-3 Input Protection: 5 A fuse V3 5sb 5 1.0 50 mV Safety Isolation: 3000 VAC input to output 1500 VAC input to ground V1 15 3 18.3 150 mV XL275-15 400029-05-4 Inrush Current: 13 A 240 VAC V2 12 5 1.0 80 mV 0.7 Leakage Current: mA XL275-15 CS 400029-03-9 Power Factor Active PFC circuitry, meets V3 5sb 5 1.0 50 mV Correction: or exceeds EN61000-3-2 V1 16 3 17.1 150 mV OUTPUT SPECIFICATIONS XL275-16 400029-06-2 V2 12 5 1.0 80 mV Total Output: 275 W XL275-16 CS 400029-04-7 Hold-up Time: Minimum 22 mS V3 5sb 5 1.0 50 mV Efficiency: Up to 91% V1 18 3 15.3 200 mV Minimum Load: No load XL275-18 400029-07-0 Over / Under Shoot: Maximum 10% at turn-on V2 12 5 1.0 80 mV XL275-18 CS 400029-08-8 PROTECTION V3 5sb 5 1.0 50 mV Overvoltage Protection: V1 and V2 latch off V1 24 3 11.5 200 mV Overpower Protection: Protected / Auto-recovery XL275-24 400030-02-9 V2 12 5 1.0 80 mV Short Circuit Protection: Auto recovery of XL275-24 CS 400030-01-1 all outputs protected against short circuit V3 5sb 5 1.0 50 mV Thermal Shutdown: Auto recovery protection V1 28 3 9.8 200 mV against over temperature XL275-28 400032-06-6 conditions V2 12 5 1.0 80 mV OPERATING SPECIFICATIONS XL275-28 CS 400032-05-8 V3 5sb 5 1.0 50 mV Operating Temperature: 25 to +50 C Temperature Derating: 2.5% / degree 50 C to 70 C V1 36 3 7.6 200 mV XL275-36 400035-02-8 Storage Temperature: 40 to +85 C V2 12 5 1.0 80 mV Forced Air Cooling: 10 CFM minimum XL275-36 CS 400035-01-0 Convection Cooling: 150W V3 5sb 5 1.0 50 mV MTBF: 645,362 hours 25 C* V1 48 3 5.7 200 mV SIGNALS XL275-48 400031-02-7 V2 12 5 1.0 80 mV Remote Sense XL275-48 CS 400031-01-9 Active Current Sharing V3 5sb 5 1.0 50 mV Passive Redundancy V1 54 3 5.1 200 mV Fan Output 1 XL275-54 400032-04-1 Fan Output 2 V2 12 5 1.0 80 mV XL275-54 CS 400032-03-3 Fan Tachometer Input V3 5sb 5 1.0 50 mV 2 Optional I C Data / Clock Power Good (PG) Output V1 56 3 4.9 200 mV XL275-56 400032-02-5 Standby Output V2 12 5 1.0 80 mV Remote Enable Input XL275-56 CS 400032-01-7 V3 5sb 5 1.0 50 mV Onboard LED Indicators See Product Specification CS = Current Sharing * 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 All information and specifications are based on our Qualstar and the Qualstar logo are registered Tel: 805-583-7744 E-mail: sales N2Power.com knowledge of the products at the time of printing. trademarks of Qualstar Corporation.
