The BXA40 Series providing up to 40 Watts, 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
two wide input voltage ranges, 18-36VDC and 36-75VDC, and is available with single outputs
from 2.9V to 12V. The BXA40 series is designed to meet ETSI telecoms interface standards
ETS300-132-2. Together with internal filtering, safety approval to IEC950 and basic insulation, the
48VDC models are ideal for telecommunications applications. The 24V models are particularly
suited to industrial and test equipment applications, featuring EN61000-4-2, -3, -4, -5 and -6
immunity compliance. Other features include low output ripple, overvoltage protection, indefinite
short circuit protection, remote enable and remote sense.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
