The NFS80 series is a 80 W universal input ac-dc power supply on a 7 x 4.25
inch card. The NFS80 series has two quad output models with a very high peak
capability on the auxiliary outputs for drive and motor applications. The NFS80
provides 80 W of output power with free air convection cooling which can be
boosted to 110 W with 20 CFM of forced 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
NFS80 series is designed for use in low power data networking, computer,
telecom and industrial applications such as servers, PABX's, storage devices,
vending machines and printers.
