ULTRA SMALL, HIGH EFFICIENCY POWER SUPPLIES N2POWER A Qualstar Company XL125 DC-DC Series XL125DC SERIES 125 Watt Chassis Mount DC-DC Converter Measures: 5 x 3 x 1.25” • 125 W DC-DC • UP TO 90% EFFICIENCY • HIGH POWER DENSITY: 3 6.7 W/in • 36 – 76 VDC • ACTIVE CURRENT SHARING • BUILT IN OR-ING DIODES FOR N+1 (OPTIONAL) • 3” X 5” SMALL FOOTPRINT • <1U HIGH: 1.25” • NO LOAD OPERATION • RoHS COMPLIANT • INPUT TO OUTPUT ISOLATION POWER SUPPLY DESIGN LEADER TM N2Power continues to lead the power density race with its new small, high efficiency open frame XL125 DC-DC Series power supplies. TWICE THE POWER IN HALF THE SP ACE Our technology yields a very small footprint, reduces wasted power, and offers the highest power density in the market in the 125 watt range. The unique design means reduced energy costs, a greater return on your Typical Mechanical Drawing: investment, higher reliability and longer Inches (millimeters), connectors and pinouts may vary with model. product life. Refer to XL125 DC-DC Product Specification for complete information. .225 5.00 UNMATCHED POWER DENSITY (5.7) (127.0) With an overall height of 1.25" and a 3" x 5" 4.55 .225 (115.6) footprint, the XL125 Series boasts a power (5.7) density of 6.7 watts per cubic inch. It is ideally suited for OEMs using industry standard 1U chassis. N2Power’s small form factor power XL125 DC - DC supplies allow you to work with additional 3.00 2.55 Height = 1.25 (31.8) “real estate” for more functionality inside your (76.2) (64.8) product. Decreased space, reduced thermal Safety ground connection point loads and lower costs will increase your 1 at plated through hole competitive edge in the market. HIGH EFFICIENCY IN A SMALL PACKAGE Lock washer Screws shown for reference only Reduced heat generation and greater reliability are key design requirements. The XL125 Series 1.25 1.00 0.06 0.19 provides up to 90% efficiency in a 125 watt (31.8) (25.4) (1.5) (4.8) DC-DC power supply. Our unique design reduces energy consumption and generates less waste heat. It requires little forced air Printed Circuit Board cooling, decreases DC loads and increases reliability and economy of operation. Specifications are subject to change without notice.
