The BXA15 Series, comprising 15 different models, 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 three wide input voltage ranges, 9-18VDC, 18-36VDC and 36-75VDC, and
is available in single and dual output versions. Designed to meet ETSI telecoms interface
standards ETS300-132-2 and BTR2511, together with internal filtering to EN55022 level A,
safety approval to EN60950 and UL1950, and isolation of 1500VDC, the 48VDC models are
ideal for telecommunications applications. The 12V and 24V models are particularly suited to
industrial, mobile telecom and test equipment applications, offering EN61000-4-2, -3, -4, -5
and -6 immunity compliance. Other features include low output ripple, overvoltage
protection, continuous short circuit protection, remote enable and remote sense.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

An optional internal filter is available, which will meet VDE0871 level A,
VDE0878 level A and EN55022 level A. Add the suffix ‘-F’ to the model
number, e.g.
BXA15-48S12-F.

For conducted noise operation of the BXA30 to VDE0871, VDE0878 and
EN55022 level B, see BXA15 and BXA30 Design Note 100.
6
Reverse voltage protection can be implemented by putting a slow blow
fuse on the negative input rail. Rate the fuse for 48VDC at 1.5A; 24VDC at
3A; 12VDC at 6A.
7
The maximum operating ambient temperature, without derating depends
on internal power dissipation and hence efficiency and cooling method.
BXA15 and BXA30 Design Note 100 provides detailed thermal
calculations and design-in details.

Test results to-date are 1,590,000 hours @ 46˚C. The MTBF figure shown
includes a calculated acceleration factor of 4.1 based on an activation
energy of -0.55 eV.
