Arc protection (Arc discharge Protection) is a feature that prevents power supply failure in the event of a single arc flash (spark). If arcing occurs repeatedly, measures such as attaching a protective resistor to the output are necessary. Some models stop the power supply output when an arc discharge is detected.

Arc discharges are caused by the breakdown of gases due to the potential difference between the output terminals and the chassis or ground. For more information on arc discharge, please refer to the glossary "Arc Discharge".

Notice: "Arc Protection" is not a function that prevents the occurrence of arc discharge.
