3 / 4 page Rev.03.08.07 bxa40s 3 of 4 Embedded Power for Business-Critical Continuity Specifications Contd. 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 200 Vdc,1.5 A for 48 Vdc inputs and 100 V, 4.5 A for 24 Vdc 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 100 V 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 2.9 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. 9 Overvoltage protection is 118% on 3.3 V output model. 10 For 2.9 V output, no short circuit protection above 90 °C baseplate temp. 11 Transient response, 25% to 100% load, 10% for 2.9 V and 3.3 V 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 24 V input 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. 14 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. 15 NOTICE: Some models do not support all options. Please contact your local Artesyn representative or use the on-line model number search tool at http://www.artesyn.com/powergroup/products.htm to find a suitable alternative.
