  • Page 25: Remote Voltage Sensing

    3-3. Remote Voltage Sensing When the DUT is connected to the power supply's output terminal, voltage regulation occurs in the DUT’s connection cable. Therefore, remote voltage sensing (V-sensing) can be used to provide the correct amount of power to the DUT. Familiarize yourself with the contents below before using V-sensing.

  • Page 26: Stability

    Stability Since V-sensing under the circumstances wherein the DUT’s cable is long and the DUT requires a large amount of power acts like a filter itself just like a part of the voltage feedback loop, this can cause problems in V-sensing. This leads to power supply itself or the output terminal’s output value becoming unstable due to the power supply's very fast responding speed.
