Pin-compatible with NFC40 Series
The BXA40-48T05-12-M provides 40 Watts of output power, has been conceived as an
applications-specific range of DC/DC converters, specifically addressing
telecommunications, industrial electronics, test equipment, mobile telecommunications
and distributed power applications. The series offers a wide input voltage range, of 36-
75VDC, and is available with a 5/鹵12V triple output. The BXA40 series is designed to
meet ETSI telecoms interface standard ETS300-132-2. With safety approval to IEC950
and basic insulation, the 48VDC model is ideal for telecommunications applications.
Other features include low output ripple, overvoltage protection, short circuit protection
and remote enable.
