The BXA10 series of dc-dc converters, comprising 7 different
models, is designed for a wide range of applications including
communications, industrial systems and mobile battery powered
systems. Packing up to 10 Watts of power into a 2 x 1 x 0.395 inch
package, with efficiencies as high as 85%, the BXA10 has wide
input ranges of 9 Vdc to 18 Vdc and 18 Vdc to 75 Vdc, and is
available in single and dual output versions. Isolation of 1500 Vdc,
approval to EN60950 2nd edition, coupled with reduced
conducted noise for simplified compliance to FCC Part 15 level A
and EN55022 level A, make the BXA10 ideal for
telecommunications and distributed power applications. Other
features include overvoltage protection, continuous short circuit
protection with automatic recovery and remote on/off, all of which
minimize the need for external circuitry and make the BXA10 a
recommended component in distributed power systems.

Notes
1At nominal input and output voltage and maximum load.
2Output ripple can be reduced to <50 mV with the addition of a 33 μF, 25 V,
AVX-TPS (or equivalent) tantalum capacitor. Consult factory for further
information.
3For units with optional remote ON/OFF, please add the suffix ‘-S’ to the model
number: e.g. BXA10-48S05-SJ. Maximum open pin voltage 14 Vdc.
4Assumes balanced loads on dual output models.
5High impedance source/long input power cable may necessitate the
introduction of an input filter.
6Typical 9 Vdc to 18 Vdc model start-up voltage is 9 V. Maximum start-up
voltage is 9.5 V (>0 °C) or 9.7 V (<0 °C).
7It is recommended that an IEC127, 250 V, fast blow fuse is used rated at 4 A
for nominal 12 V models and 2 A for 48 V models.
8To achieve compliance to EN55022-A and FCC part 15 Class A, external
capacitors of the following values are needed:
Model C1* C2 C3
BXA10-12xxxx 10 μF film, 25 V 0.22 μF film 0.22 μF film
BXA10-48xxxx 10 μF film, 100 V 0.22 μF film 0.22 μF film
(C2, C3 voltage rating application dependent)
* Siemens P.N. B32512-J1106-J or equivalent.
9The ‘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.
10 NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at
http://www.artesyn.com/powergroup/products.htm to find a suitable
alternative.
* Optional remote ON/OFF pin. Add Suffix ‘-S’ to the model number (Note 3).
