CHAPTER 19 BASIC CONNECTIONS FOR OPERATION FPS-T1U RACK

19.1 Connecting Single Load, Remote Sensing

Remote sensing is used in cases where 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 the power supply side or the load. The optimal point for the shield ground should be determined by experimentation. Refer to the power supply specifications for the maximum voltage drop allowed at the load wires.
