The BXA40-48T05-12-MJ provides 40 Watts of output power, 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 a wide input voltage range, of
36 Vdc to 75 Vdc, and is available with a 5/±12 V triple output. The BXA40 series is
designed to meet ETSI telecoms interface standard ETS300-132-2. With safety
approval to IEC950 and basic insulation, the 48 Vddc model is ideal for
telecommunications applications. Other features include low output ripple, overvoltage
protection, short circuit protection and remote enable.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

3Load regulation:
Main output (V1): 25 to 100% with 25% to 100% balanced on auxiliaries.
Auxiliary outputs (V2 and V3): 25% to 100% balanced on all outputs.
4Cross regulation:
Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%.
Auxiliary outputs (V2 and V3): main output 100% load, auxiliary 100%,
other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other
auxiliary 25% to 100%.
5Short circuit protection, ≤ 1 minute on auxiliary outputs.
6For EMI compliance to EN55022 level B please consult factory for details.
For EMI compliance to EN55022 level A, refer to BXA40 Design Note 101.
7Reverse voltage protection, refer to BXA40 Design Note 101.
8The maximum operating ambient temperature, without derating depends
on internal power dissipation and module efficiency and cooling method.
Download BXA40 Design Note 101 which provides detailed thermal
calculations and design-in hints from the Artesyn website.
9It is suggested that an external filter capacitor be used. A 4 µF (or greater)
film capacitor such as: ITW Paktron Capstick series, part number
405K100CS4 4 µF/100 V is recommended, if filtering is not used. See
BXA40 Design Note 101.
10 The unit with the suffix ‘-M’ at the end of the model number is offered as
standard with metric threaded inserts (M3). To order a unit with imperial
threaded inserts (4-40 UNC) please remove the suffix ‘-M’ from the model
number. These inserts are used for bolting the unit to a
PCB and/or fixing heatsinks.
11 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.
12 NOTICE: Some models do not support all options.
