amiciSmart Buck Boost Converter Display Display Lights Electronic Hobby Kit

(1) buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, output current range is 0-3A, with enhance heat dissipation, it can reach 4A; max output power is 35W, with enhance dissipation, it can reach 50W. (2) LCD Display: the voltage regulator module is designed with LCD, can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A. (3) Application: power supply with over-current protection?power conversion? LED constant current driver module?bilge pump, 12v lead acid battery, Drone, folding solar panel, air matress pump, LED strip, power some small 5V to 12V, 15V CPAP machine,test meter, circuit test, solar project (4) Safe Protection: with reverse connection protection at input and with anti-backflow at output terminal, so there is no need to add an anti-backflow diode when charging the battery. (5) ON/OFF Button: Short Press to select whether output . Long press (more than 3second) is used to restore default settings.IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press is used to switch display output current or output power.
