[ 2 YEAR WARRANTY ]

Providing 40W of power in a 2.2 x 2.2 x 0.5 inch package, the highly specified NFC40

Series of DC/DC converters were designed with today’s demanding applications in

mind. Inherent design specifications of the NFC40 include tight line and load

regulation and high power density. Standard features provided by all members of the

NFC40 Series are remote on/off, synchronization function, short circuit protection,

overvoltage protection and an output voltage trim function. To maximize the board

area available to system designers, the NFC40 footprint has been minimised without

compromising on features or profile. A comprehensive package of heatsink and

operating temperature options are included to further increase the flexibility offered.

Artesyn Technologies has utilised its latest patented topology implemented in SMT

and hybrid technologies to achieve this performance level. Typical applications for the

NFC40 Series include telecommunications, remote exchanges, automation equipment,

back plane power architectures and distributed power.

Mechanical notes

A All pins are actual to within 0.010 inch (0.25mm) diameter.

B Tolerances:

Imperial

0.XX ± 0.02 inch

0.XXX ± 0.005 inch

Metric

0.X ± 0.5mm

0.XX ± 0.13mm

Unless otherwise specified.

C Metric dimensions in brackets, e.g. 1.250” (31.75mm).

D Copper tracks must not be routed under the four converter stand-offs.

Total error band is defined at the static output regulation at 25°C, includ-

ing initial setting accuracy, line voltage within stated limits and load cur-

rent within stated limits.

2 Nominal input voltages are 24VDC and 48VDC.

3 Overvoltage protection threshold. Any main output overvoltage clamps

the output to a very low output voltage. A prolonged overvoltage

condition will cause the converter to fail.

4 Maximum value at full load, nominal input voltage.

5 For top-mounted heatsink option with Metric screws, add ‘-MX’ or ‘-MY’

to these model numbers. For side-mounted heatsink option, add ‘-ME’ or

‘-MS’ to the model number e.g.

NFC40-48S05-MX.

For top-mounted heatsink option with Imperial screws, add ‘-1X’ or ‘-1Y’

to these model numbers. For side-mounted heatsink option, add ‘-1E’ or

‘-1S’ to the model number e.g.

NFC40-48S05-1X.

6 For triple output units, common pins (5 and 8) should be connected

externally.

7 Output V1 must return to common 1 and outputs V2 and V3 to common 2

and 3 respectively in order to meet noise and regulation specifications.

8 The external trim function enables the tailoring of the output voltage to

the applications exact requirements. Adjustments within ±10% are

possible. On the triple output models the auxiliary output voltages (output

2 and 3) will vary proportionally to the main output.

9 An external filter capacitor is required for normal operation. The

capacitor should be capable of handling 1A/2A ripple current for 48V/24V

models. Artesyn suggests: Nippon Chemi-Con SXE series, 220µF/100V

for the NFC40-48xxx-M and the Nippon Chemi-Con LXF Series,

1500µF/50V for the NFC40-24xxx-M.

10 Extended operating temperature range. To specify an NFC40 that

operates down to –40°C, add the suffix ‘4’ or ‘-4’ to the model number

e.g.

NFC40-48S05-M4

NFC40-48S05-4

for Metric and Imperial screw

measurements respectively.

11 Case temperature must not exceed +105°C. Curve may be extended or

restricted depending on available cooling.

Derating Curves

The derating curves shown are based on measurements of actual

power supplies and reflect Artesyn Technologies conservative

design guidelines. Adherence to these guidelines contributes to the

high reliability of our products by restricting the maximum operating

semiconductor junction temperatures to 125°C which is well below

the component manufacturers’ maximum limits.

Key to power derating curves:

Natural convection.

150 linear feet per minute forced air flow.

300 linear feet per minute forced air flow.

Heatsink options:

Two heatsink kits are available for the NFC40: top mounted and side

mounted. Each heatsink may be oriented parallel to or perpendicular

to the direction of the pins, thus providing optimum flexibility for

cooling requirements.

Top mounted heatsink

If board area is at a premium in your application then the top

mounted heatsink should be used. This heatsink kit comes com-

plete with screws and is mounted as shown in the diagram over. To

fit the heatsink, place it in the required orientation, and tighten the

four screws. 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.

Side mounted heatsink

With many applications, e.g. rack systems, the profile must be kept

to a minimum. The side mounted heatsink is intended to meet the

requirements of low profile applications. The NFC40 with this

heatsink option is 12.7mm (0.5 inch) high. The kit contains two side

mounted heatsinks, which must be fitted opposite to one another on

the NFC40. The order number for the side mounted heatsink is:

NFC40-HTSK-S

Factory fitted heatsinks

As a further option, Artesyn Technologies offers factory fitted

heatsinks. Simply add the suffix as described by the diagrams

above to the part number: e.g.

NFC40-48S12-MY

NFC40-

48S12-1Y

for Metric and Imperial screws respectively.
