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.

Convection cooled, maximum 50W output power.
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 47µF
capacitor.
5 Total regulation is defined as the static output regulation at 25°C, 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 > 50°C, 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
