BXB75 SERIES
Single output
[ 2 YEAR WARRANTY ]
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
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.
