VER : A_1 update : 2015.03.16 DC-DC Brick BR400 SERIES 400 Watts DESCRIPTION KEY FEATURES Input under Voltage Protection The BR400 is an isolated DC-DC converter that uses an industry nonstandard Over Current Protection (Hiccup Mode) quarter-brick structure and features high efficiency and power density. Short Circuit Protection (Hiccup Mode) It provides 12 V outputs and supports the maximum output current of 33 A. Over Voltage Protection (Hiccup Mode) Over Temperature Protection (Self-recovery) Activates Hardware and Software * Two BR400s can be connected in parallel to provide the maximum output current of 54 A. Digitally Adjusts the Voltage * The BR400 communicates over PMBus 1.1 to support monitoring and alarm PMBus Revision 1.1 compliant * reporting functions, such as monitoring the output voltage and current, input voltage, digitally adjusting the voltage, and activating software. Secondary ON/OFF Control * Pre-Bias Function * Peak Efficiency:96%(12V,16.5A) UL60950-1 and CSA C22.2 No. 60950-1-07 Meet UL94V-0 Flammability Requirements Rohs6 Compliant Size: 2.28 x 1.45 x 0.5 Inches 3-Years Product Warranty *BR400-12S without this function ELECTRICAL SPECIFICATIONS Conditions: TA = 25°C (77°F), Airflow = 1.5 m/s (300 LFM), Vin = 48 V, unless otherwise notes.
