NFC40-24T05-15-M4 Single and triple output 40 Watt Wide input DC/DC converters

• 40 Watts in a 2.2 x 2.2 x 0.5 inch case
• Base plate cooled patented topology
• Remote ON/OFF control
• Short circuit protection
• Industry standard pin-out
• UL, CSA and VDE safety approvals
• Extended operating temperature range option
• Fixed frequency operation
 

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.

Heatsink options:

Two heatsink kits are available for the NFC40: top mounted and sidemounted. Each heatsink may be

oriented parallel to or perpendicularto the direction of the pins, thus providing optimum flexibility forcooling

requirements.

Top mounted heatsinkIf

board area is at a premium in your application then the topmounted heatsink should be used. This heatsink

kit comes com-plete with screws and is mounted as shown in the diagram over. Tofit the heatsink, place it in

the required orientation, and tighten thefour screws. The order number for the top mounted heatsink kit with

Metric screws is: NFC40-HTSK-T. The order number for the topmounted heatsink kit with Imperial screws is:

NFC40-HTSK-T-I.

Side mounted heatsink

With many applications, e.g. rack systems, the profile must be keptto a minimum. The side mounted heatsink

is intended to meet therequirements of low profile applications. The NFC40 with thisheatsink option is 12.7mm

(0.5 inch) high. The kit contains two sidemounted heatsinks, which must be fitted opposite to one another onthe

NFC40. The order number for the side mounted heatsink is:NFC40-HTSK-SFactory fitted heatsinksAs a further

option, Artesyn Technologies offers factory fittedheatsinks. Simply add the suffix as described by the

diagramsabove to the part number: e.g. NFC40-48S12-MY or NFC40-48S12-1Y for Metric and Imperial screws

respectively.
