3.9.8 Connecting Single Loads, Remote Sensing
Fig.3-11 shows recommended remote sensing connection for single loads. Remote
sensing is used when, in Constant Voltage mode, the load regulation is important at the
load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires
are used, the shield should be connected to the ground at one point, either at the power
supply chassis or the load ground. The optimal point for the shield ground should be
determined by experimentation.

3.9.9 Connecting Multiple Loads, Radial Distribution Method
Fig.3-12 shows multiple loads connected to one supply. Each load should be connected
to the power supply’s output terminals using separate airs of wires. It is recommended
that each pair of wires will be as short as possible and twisted or shielded to minimize
noise pick-up and radiation. The sense wires should be connected to the power supply
output terminals or to the load with the most critical load regulation requirement.
