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
18 Vdc, 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.

Maximum.
Maximum figure at full load (nominal).
Low line to high line.
Full load to no load.
An 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.
Conducted 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
Reverse 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.
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.
NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at
