POTTING MATERIAL  
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 0.1uf capacitor.  
3.Test condition: 48VDC input for 350~1050mA, 28VDC input for 1400mA.  
4.Output voltage will always step down by 3 volts from input DC voltage.  
5.The output of LDD-H should not be connected to the input of the same unit or output from other sources.
