AC220V to AC24V or AC12V adjustable power supply [Copy link]

Hello everyone! Is there any adjustable power supply that can convert AC220V to AC24V or AC12V? It is used to test AC24V LED light strips, with ammeter and voltmeter display. It is similar to 0V~30V of DC power supply. Thank you

Buy an auto-voltage regulator. The output is adjustable from zero to a maximum of 250V. It is not expensive. You need to prepare your own ammeter and voltmeter.

Then you can use a transformer. Power supplies with adjustable AC output are basically for special purposes and are very expensive.

In addition, buy a dual 12V transformer with a center tap. The power is determined by your needs. In this way, half of it is 12V and all of it is 24V.

If you just want to debug, you can buy a variable frequency power supply if you have the conditions, but remember it is not a frequency converter. The variable frequency power supply is very close to the ideal AC power supply, which can output the voltage and frequency of the power grid in any country. The output AC voltage and frequency can be adjusted. If the power is sufficient, you don't need to add anything yourself, and you can directly use it for production debugging.
