Load Wiring Length for Operation with Sense Lines
For applications using remote sensing, you must limit the voltage drop
across each load line. Figure 2-3 shows some allowable wire lengths for a
given load current and wire size. We recommend that you use the larger
load wiring to ensure a smaller voltage drop (1 V typical maximum),
although units will compensate for up to 5 V drop in each line. See also
“Local and Remote Sensing”.
