BXA40

Embedded Power for Business-Critical Continuity BXA40 Series Single output Total Power: 40W Input Voltage: 18 - 36VDC 36 - 75VDC # of Outputs: Single Rev.03.08.07 bxa40s 1 of 4 Special Features • Pin-compatible with NFC40 Series • Meets telecom power supply interface standard ETS300-132-2 • EN60950, CSA C22.2 No. 950 and UL1950 safety approvals • EN61000-4-2, -3, -4, -5, -6 immunity compliant • Fixed frequency operation at 350 kHz typ. • MTBF in excess of 500,000 hours • Basic insulation system with 1500 Vdc isolation • Remote sense on low voltage logic outputs • Output voltage trim • Available RoHS compliant • 2 year warranty 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.
