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.
