Current Selection Of Power Supply Module
Aug 08, 2018

Because of the high efficiency of switching power supply, generally can reach more than 80%, so in its output current selection, should accurately measure or calculate the maximum absorption current of electrical equipment, so that the selected switching power supply has a high performance price ratio, usually output calculation formula:

Is=kif

Type medium: is-switching power supply rated output current;

if-the maximum absorption current of electric equipment; K-margin coefficient, generally take 1.5~1.8.
