reetings colleagues. Conducted a power switch test between ports. Wiring diagram Power port 1 much hyb-bec 12 + Mauch PL-sensor., Power port 2 Hex Power Brick Mini. Power was supplied on two lines at the same time. I turned off the Power port 1 while the controller switched to power from the Power port 2, after 5 seconds I turned on the Power port 1 while the Mauch PL-sensor burned down. After that, my Pixhawk 2 ‘The Cube will not start.
It was not the current sensor that burned down, but the controller itself. Do the test yourself. the controller( pixhawk 2.1) is connected via a standard current sensor port 1 and port 2 simultaneously. Disconnect port 1 - the controller will switch to the power of port 2, after 5 seconds, turn on port 1 - the controller will burn.
I can not understand the reason, since the controller should switch from power port 1 to port 2 and back
