3.9.5. Connecting Single Loads, Remote Sensing
Fig.3-4 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.
