Tips
Adjustable output voltage is the biggest characteristic of regulated DC power supply. Because the voltage is adjustable, the scope of application is wider, widely used in the laboratory and maintenance occasions, so it is also called “maintenance power supply”, “experimental power supply”.
In practice, products used in laboratory and maintenance applications will add more additional practical functions, such as adjustable current limiting function, tracking function, etc. The current limiting function is more practical. It can set the maximum current output of the regulated power supply. When the current output exceeds the set value, the voltage will fall, but the current will not continue to increase, similar to entering the constant current mode. Some power supplies provide over-current protection function. Once the current exceeds the preset value, it will enter the protection state, cut off the output, and restart the power supply to restore the output. In the experiment and maintenance, due to misoperation or circuit fault, short circuit often occurs. Using the current limiting function not only protects the safety of the power supply itself, but also protects the components on the circuit, so that they will not be impacted by large current. In general, the current of adjustable DC power supply in the market is not large, and the output current is 1-10A, which can meet the maintenance and experiment needs of ordinary digital products and mobile phone communication products.
