The BXA40 Series providing up to 40 Watts, has been conceived as an applications specific range of dc-dc converters, specifically addressing telecommunications, industrial electronics, test equipment, mobile telecommunications and distributed power applications. The series offers two wide input voltage ranges, 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc, and is available with single outputs from 2.9 V to 12 V. The BXA40 series is designed to meet ETSI telecoms interface standards ETS300-132-2. Together with internal filtering, safety approval to IEC950 and basic insulation, the 48 V models are ideal for telecommunications applications. The 24 V models are particularly suited to industrial and test equipment applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliance. Other features include low output ripple, overvoltage protection, indefinite short circuit protection, remote enable and remote sense.

Notes
1 2 3 4 5 6 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. 9 10 11 12 Overvoltage protection is 118% on 3.3 V output model. For 2.9 V output, no short circuit protection above 90 C baseplate temp. Transient response, 25% to 100% load, 10% for 2.9 V and 3.3 V models. 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 F (or greater) film capacitor such as: ITW Paktron Capstick series, part number 405K100CS4 4 F/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.
