5.8 Remote Sensing
When the power output current is too large or the connecting line is too long, a large voltage drop will be
generated on the connection line, resulting in a decrease in the voltage obtained by the load. This series
provides a remote compensation terminal on the rear panel, which can compensate for the line loss of the
connecting line, so that the voltage at the load end is equal to the voltage set by the power supply.

1.
2. Remove the shortcircuit plate between Vs+ and Vo+ and Vs- and Vo-.
3. Use the output terminal on the front panel or Vo+ and Vo- on the rear panel to connect to
4. Use Vs+ on the rear panel to connect the positive end of the load, Vs- connect to the
Notes
1.
It would be better to strand Vs+ and Vs- together to enhance the anti-interference capability.
2.
If not use remote sensing, please separately short connect Vs+ and Vo+, Vs- and Vo-.
