Comment éviter l’inversion de raccordement des fils de télé régulation (remote sense)

It is important to ensure the correct polarities of the power supply are use in the remote sense circuit; the +ve sense wire should connect at the load near the +ve Vload connection, and the –ve sense wire to the -ve Vload connection.

If the remote sense wires are crossed-connected (i.e. +ve sense to –Vload and –ve sense to +Vload), current will flow in the sense lines and ultimately this will burn out the internal R-sense resistors, causing the power supply to malfunction.

Typically, these internal R-sense resistors are around 10 to 100 Ohms with a maximum rating of 0.5W.
