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 9-18VDC, 18-
36VDC and 36-75VDC, and offers standard output voltages of 3.3V, 5V, 12V and
15V in single and dual output configurations. Continuous short circuit protection,
overvoltage protection, 60mV output ripple and EN55022 level A conducted
noise compliance minimize design-in time, cost and eliminate the need for
external components.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

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-F.
6Conducted noise filtering to EN55022 level B may be accomplished by
putting the following capacitors across the input pins.
12VDC 5µF ceramic X7R dielectric type
24VDC 3µF ceramic X7R dielectric type
48VDC 1µF 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 250mA at 48VDC input, 500mA
at 24VDC input and 1000mA at 12VDC input.
8NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at
