LCD1602 is used to display information, and keys and encoders are used to adjust parameters, which makes human-computer interaction more convenient. The CV and CC loops composed of high- power devices and peripheral precision operational amplifiers greatly improve the module performance. With its own fan to dissipate heat, the temperature rise is small. Full digital display, convenient and easy to use. Can output at constant voltage and constant current. Using advanced microprocessor, the output voltage and current can be accurately adjusted by pressing the key. Can set the automatic output after power-on. With input undervoltage protection (LVP), output overvoltage protection (OVP) and output overcurrent protection (OCP). With communication function, it is convenient for secondary development. With booster MPPT function, it is suitable for solar panel booster charging to capture the maximum output power of Tianyang energy panel. The output can be turned off to 0, which is safer and more convenient than the traditional Boost booster.
