DC/DC CONVERTERS 30W Wide Input DC/DC Converters
1
2 YEAR WARRANTY
BXA30 Series
Tr i pl e o u t pu t
Pin-compatible with BXA15 series
Designed to meet telecom power supply interface
standard ETS300-132-2
UL, CSA and VDE approvals
VDE0878 and EN55022 conducted emissions level A
EN61000-4-2, -3, -4, -5, -6 immunity compliant
Fixed frequency operation at 350kHz
MTBF in excess of 7,005,000 hours (demonstrated)
Basic insulation system
The BXA30 triple output Series, comprising 2 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.
Designed to meet ETSI telecoms interface standards ETS300-132-2 and BTR2511, together
with internal filtering to EN55022 level A, safety approval to EN60950 and UL1950, and basic
insulation of 1500VDC, the 48VDC model is ideal for telecommunications applications.
The 24V model is particularly suited to industrial, mobile telecom and test equipment
applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliant. Other features
include low output ripple, overvoltage protection, short circuit protection, remote enable.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
