Embedded Power for Business-Critical Continuity BXB75 Series Single output Total Power: 50 - 75W Input Voltage: 36 - 75VDC # of Outputs: Single Rev.03.08.07 bxb75s 1 of 4 Special Features • Industry standard footprint MTBF >1.4 million hours (Bellcore 332) • Input voltage to ETS300-132-2 • Adjustable output voltage • No minimum load required • Separate case ground pin • 2:1 input range for battery powered applications • Undervoltage lockout (UVLO) • UL, VDE and CSA safety approvals • Available RoHS compliant • 2 year warranty The BXB75 Series are high power density dc-dc converters packaged in the industry standard footprint (2.40 x 2.28 x 0.50 inches) to give designers optimum choices when specifying for both new and replacement designs. Suitable for a wide range of applications in nearly any industry, the BXB75 was particularly designed with communication and distributed power applications in mind. Using Bellcore 332, the MTBF is greater than 1,400,000 hours. Aluminum baseplate technology with four threaded M3 inserts makes heatsink attachment and optimum thermal management easy. The BXB75 series is approved to IEC950 by UL, CSA and VDE.
