Notes
1 Nominal line, at no load.
2 Low line to high line at full load.
3 Full load to no-load at nominal line.
4 For conducted noise operation of the BXA40 to VDE0871, VDE0878 and
EN55022 level B, see BXA40 Design Note 101.
5 Reverse voltage protection can be implemented by putting a slow blow
fuse on the positive input rail. Rate the fuse at 200VDC,1.5A for 48VDC
inputs and 100V, 4.5A for 24VDC input units.
6 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.
7 Do not exceed a dv/dt rate of 100V per second at the trim pin input if
output current is less than 0.4% lo max.
8 Remote sense is offered as standard on the 2.9V and 3.3V products. The
BXA40-24S05 and BXA40-48S05 come with remote sense as an option.
Remote sense design is designated by the suffix ‘-S’ e.g. BXA40-48S05-
SM (for units with metric inserts), BXA40-48S05-S (for units with imperial
inserts). For models without remote sense option, pin 5 and pin 6 are
absent.
9 Overvoltage protection is 118% on 3.3V output model.
10 For 2.9V output, no short circuit protection above 90
°C baseplate temp.
11 Transient response, 25% to 100% load, 10% for 2.9V and 3.3V models.
12 Units with the suffix ‘-M’ at the end of the model number are offered as
standard with metric threaded inserts (M3). To order units 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.
13 An external filter capacitor is necessary for safe operation of the 24V input
models. It is also suggested that an external filter capacitor be used on the
48V input models. A 4µF (or greater) film capacitor such as: ITW Paktron
Capstick series, part number 405K100CS4 4µF/100V is recommended, if
filtering is not used. See BXA40 Design Note 101.
14 A top mounted heatsink kit is available for the BXA40. The heatsink may be
oriented parallel to or perpendicular to the direction of the pins, thus
providing optimum flexibility for cooling requirements. The order number for
the top mounted heatsink kit with metric screws is ‘NFC40-HTSK-T’. The
order number for the top mounted heatsink kit with imperial screws is
‘NFC40-HTSK-I’. See Design Note 101 for ambient temperature derating
calculations.
