For electronic products, they need to be maintained on a daily basis so that they can be used for a longer time. What are the protection methods for 120W led power supply 12v 24v? There are 5 ways as below:

Overvoltage/overcurrent/overload/overtemperature protection means that the strip led power supply is threatened by changes in internal and external conditions such as input power supply, load, environment, cooling circuit or device failure, and the power supply cannot work normally. A protective action that occurs when the relevant circuit function is activated.

1. Restart (after disconnecting the 120W led power supply and turning it on again, the power supply will return to normal. There are two types of automatic and manual);

2. Hiccup (intermittent output);

3. Fold back limiting (a method that can linearly reduce the output current to a normal value when the load is close to a short circuit);

4. Current limiting (Constant current lim or constant current, which can limit the output current from increasing indefinitely due to overload or short circuit of the load. Even if the load is short-circuited, it will not cause equipment shutdown and power supply damage).

5.Downtime overcurrent/overload/overvoltage/overtemperature fault, usually refers to a dangerous state when the output current/power/(or input) voltage and the temperature of the heat sink exceed the protection threshold above the rated value of the power supply
