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.
