Connecting Single Loads, Remote Sensing

There is a potential shock hazard at the sense point when using power supply with an output
voltage greater than 60VDC. Ensure that the connections at the load end are shielded to prevent
accidental contact with hazardous voltages.
Bei Einsatz einer Stromversorgung mit einer Ausgangsspannung von über 60VDC besteht am
lastseitigen Sense-Punkt die potentielle Gefahr eines elektrischen Schlags. Stellen Sie sicher,
dass die Anschlüsse an der Last abgedeckt sind, um versehentlichen Kontakt mit gefährlicher
Spannung zu vermeiden.
When using shielded sense wires, ground the shield in one place only. The location can be the
power supply chassis or one of the output terminals.
Figure 2–2 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.
