Maximum continuous output power not to exceed 175 W. Refer to Figure 1 for the derating curve. 2 200 LFM (250 LFM with cover) forced air cooling from the longer side. Maximum continuous output power not to exceed 250 W. 3 Figure is peak-to-peak for room temperature rating. Output noise measurements are made across a 20 MHz bandwidth using a 6 inch twisted pair, terminated with a 10 µF tantalum capacitor and a 0.1 µF ceramic capacitor. 4 CAUTION: Allow a minimum of 1 second after disconnecting line power when making thermal measurements. For optimum reliability no part of the heatsink should exceed 115 °C and no semi-conductor case temperature should exceed 120 °C. Ripple (3) Total Regulation Model Numbers (9, 10) 120 mV ± 2.0% NLP250N-48S12J 5 No external filtering required during conducted emissions testing but some applications may require additional filtering to achieve system compliance. Compliance with radiated EMI specifications may require mounting in a suitable enclosure. 6 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 7 5 V sb (standby) output is available whenever DC input is present, regardless of remote ON/OFF signal status. 12 V (fan) present when main output is present. 8 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. 9 NOTICE: Please contact your local Emerson representative or visit our website at http://www.PowerConversion.com.
