When producing the power adapter, it is required to have safety protection. The following power adapter SaiYue Technology manufacturers will describe in detail several protection functions of the power adapter when the loop is damaged.

1. Overvoltage protection

If the optocoupler is damaged or the TL431 voltage divider network is affected, the power adapter must stop working immediately and remain in this state until the user restarts the adapter.

2. Short circuit protection

Requirements must be able to withstand continuous output, short circuit without damage. When the fault disappears, the adapter must be able to recover from protected mode and provide rated power again.

3. Over temperature protection

If the temperature of the power adapter exceeds a certain temperature value, the adapter is at risk of damage. To avoid this, it is necessary to continuously monitor the temperature with a thermal sensor. When the temperature exceeds the limit set by the designer, the adapter will continue to shut down; when the user restarts the power supply and the temperature drops, the power adapter resets.

4. Over power protection

For some power supplies, it is important that under worst-case conditions, such as when the load draws too much current, the maximum output current remains under control without actually shorting out.
