Artesyn NFS40 User Manual

The NFS40 series is a 40 W universal input ac-dc power supply on a
5" x 3" card with a maximum component height of 1.2" for use in
1U applications. The NFS40 series is available with a wide range of
models in the industry standard 5" x 3" footprint and has proven
itself to be highly reliable and versatile product for a wide range of
communication and industrial applications. The NFS40 provides
40 W of output power with free air convection cooling which can
be boosted to 50 W with 20 CFM of air. Standard features include
OVP and short-circuit protection. The series, with full international
safety approval and the CE mark, meets conducted noise
EN55022 level A. The NFS40 series is designed for use in low
power data networking, computer, telecom and industrial
applications such as hubs, routers, POS terminals, cable modems,
PABX's, industrial PC's and machine control.
