Rev.A1 28/MAY/2010 High Output Power, High Efficiency Quarter Brick DC8012-000G QB24-5-150 Module: 18dc to 36dc Input 5dc Output, Output Power Up to 150W World's Most Advanced High Power Density

3 Rev.A1 28/MAY/2010 High Output Power, High Efficiency Quarter Brick DC G QB Module: 18dc to 36dc Input 5dc Output, Output Power Up to 150W World's Most Advanced High Power Density DC-DC Converters. OPTIONS Remote On/Off Logic Configuration DESCRIPTION: Quarter Brick modules are DC-DC converter designed for use in distributed power architectures, workstations, EDP equipment and telecommunications. The Quarter Brick modules may be used as from, fit and function replacements for industry standard Quarter brick modules. All use planar transformer and surface mount constructions to produce up to 150W in a Quarter brick package. FEATURES: Industry Standard Quarter Brick: 57.9mm x 36.8mm x 12.7mm (2.28in. x 1.45in. x 0.50in.)(Typical) High Power Density: Up to 90W/in.^3 High Efficiency: 91% Typical Low Output Noise Metal Baseplate Thermal Protection Input Under oltage Protection Output Over oltage Protection Current Limit/Short Circuit Protection Adjustable Output oltage: 90% to 110% of o,set Remote Sense Remote ON/OFF Control: Positive Logic RoHS Compliant 2
