0-30V 2mA-3A Current Limiting Protection DC Regulated Power Supply DIY Kit
When electronic hobbyists do various circuit experiments, they all need a high-performance regulated power supply to provide DC voltage. Although the switching power supply has the advantages of high efficiency and small size, high-frequency interference is inevitably left, and the linear stabilized power supply is still the choice of enthusiasts and even professional manufacturers due to its extremely low interference and good isolation.
This circuit is a high-quality continuously adjustable regulated power supply with a voltage adjustment range of 0-30V. It also includes a current output limiting circuit, which effectively controls the maximum output current from 2 mA to 3 A. This feature is continuously adjustable. Let this stabilized power supply become an indispensable weapon for circuit experiments. It can limit the current to the typical maximum working current of the experimental circuit and turn on the power boldly, without worrying about the large current destroying the experimental circuit due to failure or installation errors.
