Manieren om verkeerd om aansluiten van remote sense kabels te vermijden

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.
