NOTE
1.All parameters are specified at normal input(24VDC), 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.The output of LDB-L should not be connected to the input of the same unit or output from other sources.
