NFS40 MEDICAL SERIES Single and triple output * * * * * * The NFS40 medical series is a 40W universal input AC/DC power supply on a 5 x 3 inch card with a maximum component height of 1.2 inches for use in medical applications. The NFS40 medical series has the same generic feature set as the standard NFS40 series but has been designed with lower safety ground leakage and higher isolation as required for medical safety approval. The NFS40 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 medical safety approval to EN60601 and UL2601 and the CE mark, meets conducted emissions EN55022 level A. The NFS40 medical series is designed for use in low power medical, dental and laboratory applications such as dialysis machines, monitoring equipment, instrumentation and infusion pump controls.

Natural convection cooling, 40W maximum. Forced air, 20 CFM at 1 atmosphere, 50W 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. 4 50MHz bandwidth, peak-to-peak, measured differentially. 5 Total regulation is defined as the static output regulation at 25C, including initial tolerance, load currents within stated limits, and output voltages adjusted to their factory settings. Also, 0.25 IA / IB 5.0 to maintain stated regulation. 6 A minimum load of 0.5A is required on the +5V output to obtain full current from the negative output. 7 Single output models have floating outputs which may be referenced as either positive or negative. 8 Derating curve is application specific for ambient temperatures >50C, for optimum reliability no part of the heatsink should exceed 120oC and no semiconductor case temperature should exceed 130oC. 9 Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. 10 Although the minimum output current of the NFS40-79XX is 0A, a 4W minimum load is required to achieve design MTBF. 11 Three orthogonal axes, sweep at 1 octave/min, 5 minute dwell at four major resonances. 12 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 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 The NFS40 heatsink must be grounded in order to meet safety requirements. The heatsink can be grounded by connecting the ground pad of the mounting hole near the output connector with the ground pad of the mounting hole near P1. Use metal standoffs 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'.
