Overvoltage provides protection when the power supply exceeds the preset voltage limit. When the power supply’s output exceeds the preset voltage limit, the output will disable and an overvoltage indicator will appear.
When the current flowing through a power supply reaches the preset limit, it enters a constant current operating mode, which provides overcurrent protection. The voltage usually goes down in constant current mode, and the current remains at the current limit setting. If overcurrent protection is enabled, it shuts down the output to prevent too much current from flowing out. Typically, overcurrent protection is off by default, and it is off when shipped from the factory. Use the overcurrent protection feature to safeguard your setup.
