The BXA3 Series of dc-dc converters is designed to offer the
optimum cost/benefit power solution for a wide variety of
applications including public and private telecommunications,
industrial systems and process and test equipment. The series
consists of 9 models with input voltages of 9 Vdc to 18Vdc, 18 Vdc
to 36 Vdc and 36 Vdc to 75 Vdc, and offers standard output
voltages of 3.3 V, 5 V, 12 V and 15 V in single and dual output
configurations. Continuous short-circuit protection, overvoltage
protection, 60 mV output ripple and EN55022 level A conducted
noise compliance minimize design-in time, cost and eliminate the
need for external components.

Notes
1Maximum.
2Maximum figure at full load (nominal).
3Low line to high line.
4Full load to no load.
5An optional internal filter is available. When the filter is added, the BXA3
will meet VDE0871-A, VDE0878-A and EN55022-A. Add the suffix ‘-F’ to
the model number, e.g. BXA3-12S15-FJ.
6Conducted noise filtering to EN55022 level B may be accomplished by
putting the following capacitors across the input pins.
12 Vdc 5 μF ceramic X7R dielectric type
24 Vdc 3 μF ceramic X7R dielectric type
48 Vdc 1 μF ceramic X7R dielectric type
7Reverse voltage protection can be implemented by putting a fast blow fuse
on the positive input rail. Rate the fuse for 250 mA at 48 Vdc input, 500 mA
at 24 Vdc input and 1000 mA at 12 Vdc input.
8The ‘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.
9NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at
