## Description

Description: Small size, high power, high efficiency, easy to use. Constant voltage and constant current state. It can ensure the stability of the output voltage, even when the input voltage is higher or less than the output voltage. 4-digits digital display shows output voltage, current, power, capacity and other parameters in real time by automatic or manual way. With the indicators of output "OUT", constant voltage "CV" and constant current "CC", you can check the operating state in real time. With advanced microprocessors, it allows precise adjustment of output voltage and current. With memory function, it can save 10 groups of parameters which are free to retrieve. Can set whether automatically output after power on. One key to save current voltage and current values.
