NFS50-7608 Triple output • 6.3 x 3.94 x 1.5 inch package (1U applications) • Overvoltage and short circuit protection • 50W with free air convection cooling • Regulation to no load • Isolated output option • EN55022, EN55011 conducted emissions level A • UL, VDE and CSA safety approvals • NFS50 Medical IEC601 approved The NFS50-7608 is a 50W universal input AC/DC power supply on a 6.3 x 3.94 inch card with a maximum component height of 1.5 inches for use in 1U applications. The NFS50-7608 series can regulate on the auxiliary outputs down to no load making it suitable for applications that require a heavy logic load on the main 5V output and low nominal loads with high peak capability for drives, relays or switches on the auxiliary outputs. The NFS50-7608 provides 50W of output power with free air convection cooling which can be boosted to 60W 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 A. The NFS50-7608 series is designed for use in low power data networking, computer, telecom and [ 2 YEAR WARRANTY ] industrial applications such as POS terminals, servers, PABX's, industrial PC's and process automation.
