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.

Notes

1 Nominal line, at no load.

2 Nominal line to high line, nominal line to low line.

3 Load regulation:

Main output (V1): 25 to 100% with 25% to 100% balanced on auxiliaries.

Auxiliary outputs (V2 and V3): 25% to 100% balanced on all outputs.

4 Cross regulation:

Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%.

Auxiliary outputs (V2 and V3): main output 100% load, auxiliary 100%,

other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other

auxiliary 25% to 100%.

5 Short circuit protection, ≤1 minute on auxiliary outputs.

6 For EMI compliance to EN55022 level B please consult factory for details.

For EMI compliance to EN55022 level A, refer to BXA40 Design Note 101.

7 Reverse voltage protection, refer to BXA40 Design Note 101.

8 The maximum operating ambient temperature, without derating depends

on internal power dissipation and module efficiency and cooling method.

Download BXA40 Design Note 101 which provides detailed thermal

calculations and design-in hints from the Artesyn website.

9 An external filter capacitor is necessary for safe operation of the 24V input

models. It is also suggested that an external filter capacitor be used on

the 48V input models. A 4µF (or greater) film capacitor such as: ITW

Paktron Capstick series, part number 405K100CS4 4µF/100V is

recommended, if filtering is not used. See BXA40 Design Note 101.

10 Units with the suffix ‘-M’ at the end of the model number are offered as

standard with metric threaded inserts (M3). To order units with imperial

threaded inserts (4-40 UNC) please remove the suffix ‘-M’ from the model

number. These inserts are used for bolting the unit to a PCB and/or fixing

heatsinks.

11 A top mounted heatsink kit is available for the BXA40. The heatsink may

be oriented parallel to or perpendicular to the direction of the pins, thus

providing optimum flexibility for cooling requirements. The order number

for the top mounted heatsink kit with metric screws is ‘NFC40-HTSK-T’.

The order number for the top mounted heatsink kit with imperial screws is

‘NFC40-HTSK-T-I’.
