The NFS25 series is a 25W universal input AC/DC power supply on a 5 x 3 inch card  
with a maximum component height of 1.2 inches for use in 1U applications. The NFS25  
series is available with a wide range of models in the industry standard 5 x 3 inch  
footprint and has proven itself to be reliable and versatile product for a wide range of  
communication and industrial applications. The NFS25 provides 25W of output power  
with free air convection cooling which can be boosted to 30W with 20CFM of air.  
Standard features include OVP and short circuit protection. The series, with full  
international safety approval and the CE mark, meets conducted emissions EN55022  
level A. The NFS25 series is designed for use in low power data networking, computer,  
telecom and industrial applications such as wireless switchers, hubs, POS terminals,  
PABX’s and machine control. This list is not exclusive as the generic feature of the  
series with industry standard output configurations provide a solution for most high  
volume applications including many industrial applications.
