Basic insulation system
The BXA30 triple output Series, comprising 2 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 two wide input voltage ranges, 18-36VDC and 36-75VDC.
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 basic
insulation of 1500VDC, the 48VDC model is ideal for telecommunications applications.
The 24V model is particularly suited to industrial, mobile telecom and test equipment
applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliant. Other features
include low output ripple, overvoltage protection, short circuit protection, remote enable.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

20%FL to full load. The value stated is for balanced loads.
3
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. BXA30-48T05-12-F. See BXA15 and BXA30 Design Note 100.
4
For conducted noise operation of the BXA30 to VDE0871, VDE0878 and
EN55022 level B, see BXA15 and BXA30 Design Note 100.
5
For extended operating temperature, include the heatsink option, `-1'
in the model number. Maximum heatsink height is 12.5mm, e.g.
BXA30-48T05-12-1.
6
Reverse voltage protection can be implemented by putting a slow blow
fuse on the negative input rail. Rate the fuse for 100VDC at 1.5A for the
48V model and 50VDC at 3A for the 24V model.
7
The maximum operating ambient temperature, without derating depends on
internal power dissipation 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 @ 46C. The MTBF figure shown
includes a calculated acceleration factor of 4.1 based on an activation
energy of -0.55 eV.
10
The load on the main output must exceed 10% to ensure operation of the
unit to specification.
