NFS42 SERIES
Triple output
* * * * * 6.3 x 3.9 x 1.5 package (1U applications) Overvoltage and short circuit protection 40W with free air convection EN55022, EN55011 conducted emissions level B UL, VDE, CSA and BABT safety approvals
The NFS42 series is a 40W universal input AC/DC power supply on a 6.3 x 3.9 inch card with a maximum component height of 1.5 inches for use in 1U applications. The NFS42 series is available in three standard models with a lower component count and larger footprint than most standard 40W models to ensure greater reliability. The NFS42 provides 40W of output power with free air convection cooling which can be boosted to 50W 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 B. The NFS42 series is designed for use in low power telecom and industrial applications such as PABX's, industrial PC's and machine control.

Notes
Convection cooled, maximum 40W 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 power during peak loading is 50W. 3 Forced air, 20 CFM at 1 atmosphere. Total power out, 50W maximum. 4 Figure is peak-to-peak. Output noise measurements are across a 50MHz bandwidth made using a 12 inch 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 regulation: NFS42-7608 : 0.25 x 5 IA NFS42-7627 : 0.50 x 12 Where x = -- IB NFS42-7610 : 0.30 x 12 6 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. 7 Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. 8 Artesyn Technologies recommends a minimum load of 4 Watts to achieve the design MTBF. 9 Three orthogonal axes, random vibration, 10 minute test for each axis. 10 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 1 2
AC mating connector
Molex type 09-50-3031 or equivalent with 2878 series or equivalent crimp terminal.
DC mating connector
The NFS42 uses three 4-pin paralleled connectors with 0.098 inch pin spacing. Each pin is rated at 2.5 amps. The manufacturer suggests, that for each output, all three paralleled pins be used to minimise the current contribution of each. Lowering the current delivered through each pin improves output regulation and reduces pin heating which improves connector long term reliability. Artesyn Technologies recommends, as the DC mating connector, a fourteen pin housing placed over all twelve pins simultaneously. This connector is available with polarising rib to prevent left or right pin misalignment. The relevant part is Molex type is 22-01-1143 or equivalent with associated crimp terminal 08-500114 or equivalent.
