sensing (default).
Fig.3-10 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 appli-
cations where load regulation is less critical.
3.9.8 Connecting single loads, remote sensing
Fig.3-11 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.
3.9.9 Connecting multiple loads, radial distribution method
Fig.3-12 shows multiple loads connected to one supply. Each load should be connected to the power
supply’s output terminals using separate airs of wires. It is recommended that each pair of wires will be
as short as possible and twisted or shielded to minimize noise pick-up and radiation. The sense wires
should be connected to the power supply output terminals or to the load with the most critical load regu-
lation requirement.
