3pcs 3.3V- 30V to 0.5V-33V 5A 80W DC to DC Converter Board Solar/Wind Power Automatic Boost Buck Regulator Module

Features: - High efficiency automatic lift voltage stabilizer, with voltage display - Input support to 3.3~30V, output 0.5V~33V adjustable. - Advanced aluminum housing, up to 91% efficiency - With overheating protection and shows hints. - The application range is wide and seamless automatic switching. - The input voltage can be higher than the output voltage, that is, the output voltage changes and the output voltage is kept constant. Specifications: Input voltage: DC 3.3 - 30V Output voltage: DC 0.5 - 33V Large output current: 5A Large output power: 80W Conversion efficiency: 91% (12V input, 19V output 2A measured). Module size: 78x48x22mm Instructions for Use: 1. When the indicator is red, the input voltage is displayed. When the indicator is green, the input voltage is displayed. When the indicator is red, the input voltage is displayed. 2. Press this button for about one second ~2 seconds. After loosening your hands, turn off the monitor, then press the button again to reopen the display. 3. press this key duration more than 2 seconds, after the pine hand to enter the voltage display reference voltage setting, this time the default display 3.33 and red light flicker, representing the more accurate is the input base, fast short press key change value The value of the voltage is adjusted to the appropriate value, the voltage datum of the output end is set by more than one second of the button. The green light flashes, the number is changed according to the button, and The set reference voltage is kept and returned to the normal display when the key is adjusted to the appropriate value for more than 1 second. (Note: when the voltage is the actual voltage is raised, the reference voltage will be adjusted. When the display voltage Is higher than the actual voltage, the reference voltage will be reduced). Package Included: 3 x 3.3V- 30V to 0.5V-33V 5A 80W DC to DC Converter Board
