Features: 1. Small size, high power, high efficiency and easy to use. 2. With memory function, it can store 10 sets of parameters that can be freely retrieved. 3. Using an advanced microprocessor, the output voltage and current can be precisely adjusted. 4. It can be set whether to output automatically after power-on. One button saves the current voltage and current values. 5. Output "OUT", constant voltage "CV" and constant current "CC" indication, which can check the running status in real time. 6. The 6.4-digit digital display displays output voltage, current, power, capacity and other parameters in real time, either automatically or manually. 7. Constant voltage and constant current state. It ensures the stability of the output voltage even if the input voltage is higher or lower than the output voltage.
