I used this module to build a variable power supply. I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt. With output voltages over 12 volts everything works fine. In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt. This only stops if I apply a larger load that draws at least 500mA of current.

素晴らしい製品です。私は2つの可変チャネルを備えたベンチ電源を構築するために使用しましたが、うまく機能します。

Great product. I used it to build a bench power supply with 2 variable channels and it works fine.
