NFS80 SERIES Quad output • 7.0 x 4.25 x 1.8 inch package • Overvoltage and short circuit protection • 80W with free air convection • Adjustable outputs • Isolated output • Floating fourth output • EN55022, EN55011 conducted emissions level B • UL, VDE and CSA safety approvals The NFS80 series is a 80W 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 80W of output power with free air convection cooling which can be boosted to 110W with 20CFM 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, [ 2 YEAR WARRANTY ] vending machines and printers.
