Embedded Power for Business-Critical Continuity Rev.03.08.07 bxb75s 1 of 4 BXB75 Series Single output Total Power: 50 - 75W Input Voltage: 36 - 75VDC # of Outputs: Single The BXB75 Series are high power density dc-dc converters packaged in the industry standard footprint (2.40 x 2.28 x 0.50 Special Features inches) to give designers optimum choices when specifying for • Industry standard footprint MTBF >1.4 million hours both new and replacement designs. Suitable for a wide range of (Bellcore 332) applications in nearly any industry, the BXB75 was particularly • Input voltage to ETS300-132-2 • Adjustable output voltage designed with communication and distributed power applications • No minimum load required in mind. Using Bellcore 332, the MTBF is greater than 1,400,000 • Separate case ground pin • 2:1 input range for battery hours. Aluminum baseplate technology with four threaded M3 powered applications inserts makes heatsink attachment and optimum thermal • Undervoltage lockout (UVLO) management easy. The BXB75 series is approved to IEC950 by UL, • UL, VDE and CSA safety approvals CSA and VDE. • Available RoHS compliant • 2 year warranty Safety VDE0805/EN60950/IEC950 File No. 10401-3336-0205 UL1950 File No. E136005 CSA C22.2 No. 950 File No. LR41062C Embedded Power for Business-Critical Continuity Rev.03.08.07 bxb75s Specifications 2 of 4 All specifications are typical at nominal input, full load at 25°C unless otherwise stated.
