I am trying to evaluate 2 power supply. The current measure on both the supplies are consistent but show a difference of 10-15 mA. The current I am measuring is average current around 400-800 mA. Any idea what could be the reason? Even if the power supply cable length is different, the sense lines should adjust the voltage accordingly, right?
