The BXA30 series, comprising 9 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 Vdc to 18 Vdc and 36 Vdc to 75 Vdc,
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 1500 Vdc, the 48 Vdc
models are ideal for telecommunications applications. The 12 V models are 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, continuous short circuit protection, remote enable and remote sense.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

1Nominal, at no load.
2Low line to high line.
3Full load to no-load. For duals, the value stated is for balanced loads.
4An 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. BXA30-48S12-FJ. See BXA15 and BXA30 Design Note 100.
5For conducted noise operation of the BXA30 to VDE0871, VDE0878 and
EN55022 level B, see BXA15 and BXA30 Design Note 100.
6For extended operating temperature, include the heatsink option, ‘-1’ in the
model number. Max. heatsink height is 12.5 mm, e.g. BXA30-48S15-1J
7Reverse voltage protection can be implemented by putting a slow blow
fuse on the negative input rail. Rate the fuse for 48 Vdc at 1.5 A and 12 Vdc
at 6 A.
8The 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.
9Test 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.

11 This model has the same electrical pin-out and pin pitch spacings as the
drawing on the following page. Dimensions are 76.2 x 76.2 x 14.2 mm,
±0.3 mm.
12 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
13 If remote sense is not used, connect +sense to +vout and -sense to -vout.
14 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.
