NFS80 Series

Quad output

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.

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