Pressure drop measured data:
Load current 2A voltage drop 0.0086V
Load current 5A voltage drop 0.022V
Load current 8A voltage drop 0.036V
Load current 10A voltage drop 0.042V
Load current 12A voltage drop 0.052V
Load current 15A voltage drop 0.075V
Ordinary diode voltage drop of about 0.7V, Xiao Tee diode voltage drop of about 0.4V, if calculated with 10A current: ordinary diode power consumption is 7W, Xiao Te-based diode power consumption is 4W, and the ideal diode power consumption is only 0.42W, the effect It is very obvious.
This module adopts imported chips. The original 8 milliohm ultra-low internal resistance MOS tube is connected in parallel with 4 milliohms internal resistance. It is a good alternative to traditional anti-irrigation diodes, which can effectively reduce heat, improve efficiency, and increase the utilization of solar panels.
The heat sink is more conducive to heat dissipation when used at high currents.
