AFV-P Series High Performance Programmable AC Power Supply

2.5 Remote Sense Connection
The product supports remote sense function, which monitors the voltage at the load
instead of the output terminal of the product. It ensures the delivery of accurate
voltage as programmed at the load by automatically compensating the output volt-
age drop over the connecting cable.
Remove the iron chip from the terminals “S
N
” and “S
L
” of the remote sense connector,
and connect the terminals of the remote sense connector to the corresponding ter-
minal of the load. Because the sensing leads carry only a few millamperes, the sens-
ing leads are much lighter than the load leads. The sensing leads are part of the
feedback path of the product, so they must be kept at a low resistance in order to
maintain the best performance. The sensing leads must be connected to the load
carefully, so that they will not be open-circuited. If the sensing leads are left uncon-
nected or become open-circuited during operation, the product will disable the out-
put. The sensing leads must be a twisted pair to minimize the pickup of external
noise. The sensing leads need to be connected to the load as close as possible.
