1.All parameters are specified at normal input(48VDC), rated load, 25 70% RH ambient. 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1f capacitor. 3.Test condition: 48VDC input. 4.Output voltage will always step down by 4 volts from input DC voltage. 5.The output of NLDD-H should not be connected to the input of the same unit or output from other sources. 6.The power supply is regarded as a part of the components in the system, and the final EMI test needs to be tested with the final device. If an
additional EMI filter circuit is required to meet the electromagnetic compatibility requirements, please refer to the EMC test report for details. 7.Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
