3.9.7 Connecting Single Loads, Local Sensing (default)
Fig.3-6 shows recommended load and sensing connections for a single load. The local sense lines
shown are default connections at the rear panel J2 sense connector. Local sensing is suitable for
applications where load regulation is less critical.
3.9.8 Connecting Single Loads, Remote Sensing
Fig.3-7 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.
