[ 2 YEAR WARRANTY ]
The NFS40 and NFN40 are industry standard 40 Watt power supplies with the capability to supply 50W in a forced air ambient and to automatically operate from any voltage between 85VAC and 264VAC. Use of MOSFET based switching circuits allows for enhanced features such as output regulation down to zero load (NFN40). Universal input voltage eliminates the need to change jumpers or switch settings to cater for different or widely varying line voltages. In addition to the input voltage range, VDE, UL, CSA, EN60950 and IEC950 approvals make the NFS40 and NFN40 ideal for use in equipment installed throughout the world. The fixed frequency operation of the NFN40 further reduces emissions below VDE class B and significantly reduces leakage current. These low profile switchers with high power density are intended for use in small, digital systems.

Notes
1 2 Natural convection cooled, 40W maximum. Peak output current lasting less than 30 seconds with duty cycle less than 10%. During peak loading, outputs may go outside of total regulation limits. Peak total power must not exceed 60W. Forced air, 20 CFM at 1 atmosphere, 50W maximum. Figure is peak-to-peak. Output noise is measured across a 50MHz bandwidth using a 12 inch twisted pair, terminated with a 47F capacitor. Total regulation is defined as the static output regulation at 25C, including initial tolerance, line voltage within stated limits, load currents within stated limits, and output voltages adjusted to their factory settings. Also, 0.25NFS40-7628 and NFN40-7628 power supplies as both have regulated auxiliary outputs. A minimum load of 0.5A is required on the +5V output to obtain full current from the negative output. The NFS40 offers the possibility of power sharing between outputs. Consult factory for details. 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. A 4W minimum load is required to achieve the NFS design MTBF. This restriction does not apply to the NFN series. Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. Three orthogonal axes, sweep at 1 octave/minute, 5 minute dwell at four major resonances. The NFS40-7628 and NFN40-7628 have separately linear regulated +12V and -12V outputs. The loading conditions in note 5 and note 6 do not apply. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product.

Mechanical notes
A NFS40 models only: In order to meet safety requirements, a non-metallic stand-off is mandatory for one hole as specified in the mechanical drawing. B The ground pad of the mounting hole near P1 allows system grounding through a metal stand-off. C To improve conducted noise, the ground pad of the mounting hole near the output connector should be connected with the ground pad of the mounting hole near P1 (P1 for NFS40 models and J3 on NFN40 models). Use metal stand-offs attached to a common metal chassis. This connection also significantly attenuates common mode noise. D A standard L-bracket and cover is available for mounting which contains all screws, connectors and necessary mounting hardware. Details are on page 72. Order part number `NFS40 COVER KIT'.
