BXA15 SERIES
Single and dual output
[ 2 YEAR WARRANTY ]
Pin-compatible with BXA30 series
Designed to meet telecom power supply interface
standard ETS300-132-2
UL, VDE and CSA safety approvals
VDE0878 and EN55022 conducted emissions level A
EN61000-4-2, -3, -4, -5, -6 compliant
Fixed frequency operation at 350kHz
MTBF in excess of 7,005,000 hours (demonstrated)
Basic insulation system
The BXA15 Series, comprising 15 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 three wide
input voltage ranges, 9-18VDC, 18-36VDC and 36-75VDC, and is available in single
and dual output versions. 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 isolation of 1500VDC, the 48VDC models are
ideal for telecommunications applications. The 12V and 24V models are particularly
suited to industrial, mobile telecom and test equipment applications, offering
EN61000-4-2, -3, -4, -5 and -6 immunity compliance. Other features include low
output ripple, overvoltage protection, continuous short circuit protection, remote
enable and remote sense.

An optional internal filter is available, which will meet VDE0871 level A,
VDE0878 level A and EN55022 level A. Add the suffix `-F' to the model
number, e.g. BXA15-48S12-F.
5
For conducted noise operation of the BXA30 to VDE0871, VDE0878 and
EN55022 level B, see BXA15 and BXA30 Design Note 100.
6
Reverse voltage protection can be implemented by putting a slow blow
fuse on the negative input rail. Rate the fuse for 48VDC at 1.5A; 24VDC at
3A; 12VDC at 6A.
7
The maximum operating ambient temperature, without derating depends
on internal power dissipation and hence efficiency and cooling method.
BXA15 and BXA30 Design Note 100 provides detailed thermal calculations
and design-in details.
8
Test results to-date are 1,590,000 hours @ 46C. The MTBF figure shown
includes a calculated acceleration factor of 4.1 based on an activation
energy of -0.55 eV.

This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
