Why does the power supply crash during use and can be restarted after shutting down？

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.28
In the production environment, the power supply is an important component to maintain the normal operation of equipment. However, we often encounter situations where the power supply fails and crashes, causing the equipment to malfunction. But after shutting down and restarting, it can be operated again. What is the reason for this? There may be two main points:



Overload protection:

Firstly, it may be due to the instantaneous overload of the load causing overload protection. When the power of the load appliance instantly exceeds the rated output power of the power supply, the power supply will activate an overload protection mechanism to prevent equipment damage. At this point, the power supply will turn off the output, causing a shutdown phenomenon. To solve this problem, we can take two measures.

Solution:

One way is to increase the output power of the power supply to withstand the instantaneous power peak of the load appliance. Another approach is to modify the load design to reduce the instantaneous power peak and make it within the range of the power supply. Both of these methods can effectively solve the problem of downtime caused by load overload.

Over temperature protection:

Secondly, excessive temperature rise may also lead to over temperature protection phenomena. When the temperature inside the power supply exceeds its tolerance range, the power supply will activate the over temperature protection mechanism, enter the protection state, and shut down. This situation usually occurs when the power supply is running at high load for a long time, or when there are defects in the cooling design.

Solution:

To solve this problem, we can take the following measures: optimize heat dissipation design and improve heat dissipation efficiency; Avoid prolonged high load operation; Properly reduce the working environment temperature, etc. As long as the overheating condition is resolved and the computer is restarted, the power can be restored to normal.

In summary, we need to take corresponding solutions based on different situations to address the issue of power supply failure during use. Addressing load overload issues by increasing power output or optimizing load design; To address the issue of overheating, measures such as optimizing heat dissipation design and reducing working environment temperature are taken. This can effectively ensure the normal operation of the power supply, improve the efficiency and service life of the equipment.
