  • Page 28 Note: Built-in overvoltage protection, when the actual output voltage is greater than 22 ± 2 V, the output will automatically short circuit, and limit the voltage output. In this case, you need to re-open the channel switch to resume normal output. 18 SPD1168X User Manual...

  • Page 29: Remote Mode

    When the power supply is outputting large current, the voltage on the load lead will become negligible. To ensure an accurate load, the SPD1168X provides a 4-wire (remote sense) mode of operation. In this mode, the voltage at the load terminal is detected instead of the voltage at the power supply output.
  • Page 30 Note: In 4-wire mode, the maximum compensation voltage of the power supply is 1 V. When the voltage difference between the output terminal and the Sense terminal is more than 1 V, the instrument will turn off automatically. 20 SPD1168X User Manual...
