Quarter-Brick Series
Wide Input IBC
Total Power: 168W Input Voltage: 36 - 75VDC # of Outputs: Single
Rev.04.02.08 QBWIIBC 1 of 4
Special Features
* * * * * * * * * Wide input 36 Vdc to 75 Vdc Output voltage of 12 V 10% Current rating 14 A Ultra high efficiency, 94.5% typical Industry standard quarter-brick footprint Low profile - 0.35" Remote ON/OFF Available RoHS compliant 2 Year Warranty
This series is a Quarter-Brick, wide-input intermediate bus converter (IBC). Capable of operating from any input voltage in the range 36 Vdc to 75 Vdc, this high efficiency isolated dc-dc converter module generates a semi-regulated 12 V output and can deliver up to 14 A. This series features a low profile open-frame construction and has an industry standard quarter-brick footprint.
