The reasons and solutions for the random jump of the regulated power supply are as follows:
1. The selection of the total gate capacity of the regulator access line is small, the selected circuit breaker power is not enough, and the cable wire diameter is too small;
2. The air beginning commonly used on the main switch is damaged or faulty;
3. unstable or too high surge voltage;
4. Reasons for inferior product quality;
The solution is as follows:
1. Replace the total brake capacity with a slightly larger capacity;
2. Replace an air switch and replace the relatively large cable line;
3. Replace a high-precision voltage regulator;
4. Choose products with safety and quality assurance when purchasing regulators.
Turn the power off Well, give it 700 minutes, then push it back up in ten or so and that happens in our house sometimes
