BXA40 SERIES Triple output * Meets telecom power supply interface standard ETS300-132-2 * EN60950, CSA950 and UL1950 safety approvals * EN61000-4-2, -3, -4, -5, -6 immunity compliant * Fixed frequency operation at 400kHz * MTBF in excess of 500,000 hours * Basic insulation system with 1500V isolation * Pin-compatible with NFC40 Series The BXA40 Series providing up to 40 Watts, comprising 4 different models, 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, 1836VDC and 36-75VDC, and is available with 5/12V and 5/15V triple outputs. The BXA40 series is designed to meet ETSI telecoms interface standard ETS300-132-2. With safety approval to IEC950 and basic insulation, the 48VDC models are ideal for telecommunications applications. The 24V 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, short circuit protection and remote enable.

For EMI compliance to EN55022 level A, refer to BXA40 Design Note 101. 7 Reverse voltage protection, refer to BXA40 Design Note 101. 8 The maximum operating ambient temperature, without derating depends on internal power dissipation and module efficiency and cooling method. Download BXA40 Design Note 101 which provides detailed thermal calculations and design-in hints from the Artesyn website. 9 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 4F (or greater) film capacitor such as: ITW Paktron Capstick series, part number 405K100CS4 4F/100V is recommended, if filtering is not used. See BXA40 Design Note 101. 10 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. 11 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-T-I'.
