The problem of switching power supply instead of dry battery
Switching power supply to replace dry battery is feasible in method, but it needs to meet some conditions.
1. Control current fluctuation
Battery power supply is a process of constant current, and the current will not fluctuate too much during the power supply process, but after the switching power supply is reversed, the switching power supply is affected by many aspects to generate current fluctuations, which will impact the circuit board, which will damage the circuit board.
It can be achieved by adding filtering to limit the current fluctuation at the output end of the switching power supply.
2. Select the size of the output current
The size of the switching power supply is relatively large. During the installation process, it is necessary to consider avoiding the problem of touching the metal short circuit. It is better to use dry batteries instead.
The switching power supply requires an external power supply to generate the required voltage, and the battery has stored power, which is more convenient in actual use.
3. Ensure sufficient installation space for switching power supply
The output current of the battery is generally relatively low. When choosing a switching power supply, it should be noted that the output of most switching power supplies is large.
If you just use the switching power supply instead of the concept, the high current will definitely have an impact on other electrical components in the circuit board, resulting in circuit board failure.
Therefore, to use a switching power supply instead of a dry battery, you need to consider the above three points, the current fluctuation of the switching power supply, the current output of the switching power supply, and the installation space of the power supply mode of the switching power supply.
If the above three problems can be completely solved, the switching power supply can be used to replace the dry battery, and the step of disassembling the dry battery and replacing the dry battery can be omitted.
