2 YEAR WARRANTY

BXA30 Series

Single and dual output

• 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 immunity compliant

• Fixed frequency operation at 350kHz

• MTBF in excess of 7,005,000 hours (demonstrated)

• Basic insulation system

The BXA30 series, comprising 9 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 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 models are 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, continuous short circuit

protection, remote enable and remote sense.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated

Notes

1 Nominal, at no load.

2 Low line to high line.

3 Full load to no-load. For duals, the value stated is for balanced loads.

4 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. BXA30-48S12-F. See BXA15 and BXA30 Design Note 100.

5 For conducted noise operation of the BXA30 to VDE0871, VDE0878 and

EN55022 level B, see BXA15 and BXA30 Design Note 100.

6 For extended operating temperature, include the heatsink option, ‘-1’ in the

model number. Max. heatsink height is 12.5mm, e.g. BXA30-48S15-1

7 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 and 12VDC

at 6A.

8 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.

9 Test results to-date are 1,590,000 hours @ 46˚C. The MTBF figure shown

includes a calculated acceleration factor of 4.1 based on an activation

energy of -0.55 eV.

11 This model has the same electrical pin-out and pin pitch spacings as the

drawing on the following page. Dimensions are 76.2 x 76.2 x 14.2mm,

±0.3mm.

12 This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

13 If remote sense is not used, connect +sense to +vout and -sense to -vout.
