NFC40 SERIES

Single and triple output

• 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.

... 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 or 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 ...

... Side Mounted -1S C Heatsink options: Two heatsink kits are available for the NFC40: top mounted and side 80 100 120 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 premium in your application then the top mounted heatsink should be used ...
