2.5 Remote Sense Connection

The AC source remote sense function monitors the load terminal voltage instead of
the AC source output terminal. It ensures the delivery of accurate voltage as programmed at
the load by compensating the output voltage drop over the connecting cable automatically.
You have to set Remote Sense ON so as to enable this function.
Connect the sensing wires from "Φ11/Φ22" and "COM" terminals to the load as
shown in Figure 2.5.1. As the sensing wires carry only a few milli- amperes, the wire
gauges are much smaller than the load cables. The sensing wires are part of the feedback
path of the AC source. They must be kept at a low resistance in order to maintain the best
performance. Connect the sensing wires carefully so that they will not be open-circuited.
If the sensing wires are left unconnected or become open-circuited during operation, the
AC source will disable the output. The sensing wires must be a twisted pair to minimize the
pickup of external noise. The sensing wires need to be connected as close to the load input
terminal as possible.
