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, 0.2550 °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. |Pin Connections

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. **Emerson Network Power.** The global leader in enabling business-critical continuity.
