CHAPTER 12 BASIC CONNECTIONS FOR OPERATION FPS-S1U RACK

12.1 Connecting single load, Local sensing

Local sensing is suitable for applications where load regulation is not critical. Fig 12-1 shows recommended load and sensing connections for applications with a single load.

*In Local sense applications, the +/- sense have to be connected to the

+/-V terminals of the FPS-S1U prior to operating the FPS1000 units plugged in.

12.2 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.

12.3 Multiple loads connection

If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by a pair of twisted or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig 12-3). If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.
