What is the difference between overvoltage protection and overload protection in switching mode power supply?
Overvoltage protection is the protection of AC input voltage when the voltage exceeds the rated voltage. Overload protection is the protection when the DC output terminal is overloaded.
Overpressure protection is to prevent momentary high pressure impact on the switch tube, resulting in damage to the switch tube.
Overload protection, generally large current flow through the switch, the load is too large, easy to burn out, overload protection, fuse.
