Hallo again,

I forgot to discuss the case, that high DC voltages with low output impdedance might eroneously be aplied to current input. Then, of course, current limiter arround Q2 & U8 protects shunt resistors R5, R13.

Have a look at datasheet of RCV420 for better ways to protect these shunt resistors against too high currents.

Kai
