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
industrial applications such as POS terminals, servers, PABX's, industrial PC's and
process automation.
