Introduction to the overvoltage protection function of BOSHIDA DC power module
DC power module (also called DC power module) is a common device that can convert alternating current into direct current and is used to power various electronic devices. DC power modules usually have a variety of protection functions, among which overvoltage protection is one of the important protection functions.
Overvoltage protection means that when the output voltage of the DC power module is higher than the preset value, the system will automatically perform protection operations to avoid overvoltage damage to electronic equipment. Overvoltage protection is usually implemented at the output end of the power module, because this is where power is directly supplied to electronic equipment.
If the output voltage of the power module exceeds the preset value, the overvoltage protection operations usually include the following:
1. Cut off the output power: When the power module detects that the output voltage exceeds the preset value, the system will automatically cut off the output power to avoid overvoltage damage to electronic equipment.
2. Reduce the output voltage: Some power modules will automatically reduce the output voltage to avoid overvoltage damage to electronic equipment. This method is suitable for situations where the output voltage exceeds the preset value but does not reach too high.
3. Send an alarm signal: When the power module detects that the output voltage exceeds the preset value, it will send an alarm signal to remind the user to check whether the electronic device is normal.
The above three protection methods can effectively prevent damage to electronic equipment due to overvoltage, and these protection functions are usually built into the power module and do not require users to set them by themselves.
In addition to the above protection functions, the power module also has other protection functions, such as overcurrent protection, overheating protection, etc. These protection functions can protect the power module itself and the stability and safety of power supply to electronic equipment.
The overvoltage protection function of the DC power module is a very important protection measure. It can effectively avoid damage to electronic equipment due to overvoltage and ensure the normal operation of the equipment. Therefore, when purchasing a power module, you should choose a product with multiple protection functions to ensure stable power supply for electronic equipment.
