3.9.7

Connecting single loads, local sensing (default).

Fig.3-11 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 ap-
plications where load regulation is less critical.

3.9.8

Connecting single loads, remote sensing

Fig.3-12 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.3-13 shows multiple loads connected to one supply. Each load should be connected to the power
supply’s output terminals using separate pairs 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 regulation requirement.
