Efficiency
Average system efficiency ranges from 80% to 90%. For example, when 12V is applied to an input, 5V is selected at the output and the average current drawn from the system is about 1.8A. The efficiency is 90%. This means that the output power will be determined by the formula:
(Output current) ×(Output voltage) = 1.8A×5V = 9W
The input power will be about 10W. 1W will be given away as heat.
The input current can be calculated from the formula 10W/12V= 0,83A.
With such parameters the losses on the rope stabiliser would be as high as 13W.
The efficiency of the system depending on the current consumed.
