| 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 [ 2 YEAR WARRANTY ] 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.

Peak outputs lasting less than 30 seconds with duty factor less than 10%. During peak loading output may go outside total regulation limits. Maximum output during peak loading is 60 Watts. 3 Forced air, 20 CFM at 1 atmosphere. 4 Figure is peak-to-peak. Output noise measurements are across a 50MHz bandwidth made using a 12" twisted pair, terminated with a 47F capacitor. 5 Total regulation is defined as the static output regulation at 25C, including initial tolerance, line voltage within stated limits and output voltages adjusted to their factory settings. Also, for stated I(2) regulation: I(1)/I(2)5. 6 A minimum load of 0.5 Amps is required on the +5.1V output to obtain full current from the -12V output. 7 Derating curve is application specific for ambient temperatures > 50C, for optimum reliability no part of the heatsink should exceed 110oC and no semiconductor case temperature should exceed 115oC. 8 Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. 9 Three orthogonal axes, random vibration, ten minute test for each axis. 10 A 5 Watt minimum load is recommended to achieve design MTBF. 11 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 12 NOTICE: Some models do not support all options.
