Nominal line, at no load.
Low line to high line at full load.
Full load to no-load at nominal line.
For conducted noise operation of the BXA40 to VDE0871, VDE0878 and
EN55022 level B, see BXA40 Design Note 101.
Reverse voltage protection can be implemented by putting a slow blow fuse on
the positive input rail. Rate the fuse at 200 Vdc,1.5 A for 48 Vdc inputs and 100
V, 4.5 A for 24 Vdc input units.
The maximum operating ambient temperature, without derating depends on
internal power dissipation and hence efficiency and cooling method. Download
BXA40 Design Note 101 which provides detailed thermal calculations and
design-in hints from the Artesyn website.
Do not exceed a dv/dt rate of 100 V per second at the trim pin input if output
current is less than 0.4% lo max.
Remote sense is offered as standard on the 2.9 V and 3.3 V products. The
BXA40-24S05J and BXA40-48S05J come with remote sense as an option.
Remote sense design is designated by the suffix ‘-S’ e.g. BXA40-48S05-SMJ (for
units with metric inserts), BXA40-48S05-SJ (for units with imperial inserts). For
models without remote sense option, pin 5 and pin 6 are absent.

models. It is also suggested that an external filter capacitor be used on the 48 V
input models. 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.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
