3.7.4 Single load connection, Remote Sensing
Fig. 3-3: Multiple load connections with distribution terminal
Remote Sensing is used in cases where, 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 the power supply chassis or the load
ground. The optimal point for the shield ground should be determined by experimentation. At Remote
Sensing, the maximum voltage drop allowed at the load wires is 0.5V per wire for 6V to 60V models and
2V per wire for 80V and 120V models.

3.7.5 Multiple load connections, radial distribution method
In cases of 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.
