NFS110 Series

Single and quad output

The NFS110 series is a 110W universal input AC/DC power supply on a 7 x 4.25 inch

card. The NFS110 series has four single and three quad output models and has proven

itself to be highly reliable and versatile product for a wide range of communication and

industrial applications, with a very high peak current capability on each output for drive

and motor applications. The NFS110 provides 80W of output power with free air

convection cooling which can be boosted to 110W with 20CFM of air. Standard

features include overvoltage and short circuit protection. The series, with full

international safety approval and the CE mark, meets conducted emissions EN55022

level B. The NFS110 series is designed for use in low power data networking,

computer, telecom and industrial applications such as servers, thermal printers, storage

devices, vending machines and POS equipment.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated
