## **Notes** 

- **1** Natural convection cooled, 40 W maximum. 

- **2** 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 60 W. 

- **3** Forced air, 20 CFM at 1 atmosphere, 50 W maximum. 

- **4** Figure is peak-to-peak. Output noise is measured across a 50 MHz bandwidth using a 12 inch twisted pair, terminated with a 47 µF capacitor. 

- **5** Total regulation is defined as the static output regulation at 25 °C, including initial tolerance, line voltage within stated limits, load currents within stated limits, and output voltages adjusted to their factory settings. Also, 0.25<I(A)/ I(B)<5.0 to maintain stated regulation. This does not apply to the NFS40-7628J power supply as it has regulated auxiliary outputs. 

- **6** A minimum load of 0.5 A is required on the +5 V output to obtain full current from the negative output. 

- **7** The NFS40 offers the possibility of power sharing between outputs. Consult factory for details. 

- **8** Derating curve is application specific for ambient temperatures >50 °C, for optimum reliability no part of the heatsink should exceed 110[o] C and no semiconductor case temperature should exceed 115[o] C. 

- **9** A 4 W minimum load is recommended to achieve the design MTBF. 

- **10** Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements.

- **A** In order to meet safety requirements, a non-metallic stand-off is mandatory for one hole as specified in the mechanical drawing above. 

While every precaution has been taken to ensure accuracy and completeness in this literature, Emerson Network Power assumes no responsibility, and disclaims all liability for damages resulting from use of this information or for any errors or omissions. 

- **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.  Use metal stand-offs attached to a common metal chassis. This connection also significantly attenuates common mode noise. 

- **D** A standard enclosure kit is available for mounting which contains all screws, connectors and necessary mounting hardware. Order part number NFS40CJ.
