2 / 2 page Notes 1 Convection cooled, maximum 40W output power. 2 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 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 regulation: NFS42-7608 : 0.25 ≤ x ≤ 5 IA NFS42-7627 : 0.50 ≤ x ≤ 12 Where x = — NFS42-7610 : 0.30 ≤ x ≤ 12 IB 6 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. 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.

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 08-50- 0114 or equivalent. Mechanical notes A A standard L-bracket and cover is available for mounting which contains all screws, connectors and necessary mounting hardware. Details are on page 83.
