Remote sensing monitoring function of programmable DC power supply:

In order to reduce the effect of voltage drop caused by load line impedance, programmable DC power supply has the function of applying stable voltage to load terminals.

Influence of wire length of programmable DC power supply on load terminal voltage

500kW load bank
 

By CHANGING the cable length, the voltage changes of power terminals and load terminals flowing through rectangular wave load current are measured under the setting conditions as shown in the following figure.

According to the following waveform diagram, when the cable length is 0.3m and 5m, the voltage at the output end of the programmable DC power supply does not change much. However, when the cable length is 0.3m and 5m, the voltage at the load output varies greatly.

When the cable length is 5m, the load output without remote sensing monitoring function and the voltage waveform in use are compared. When the remote sensing monitoring function of the programmable DC power supply is used, the voltage at the output end of the load does not change and the voltage is relatively stable.
