BXA40 SERIES
Triple output
[ 2 YEAR WARRANTY ]
• 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, 18-
36VDC 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.
