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
Vdc to 36 Vdc and 36 Vdc to 75 Vdc, and is available with single
outputs from 2.9 V to 12 V. 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 48 V models are ideal for telecommunications applications.
The 24 V 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.
