3pcs Solar Charge Controller Module Lithium Battery Lead Acid Battery Charger Boost Buck Circuit Board Constant Current

Manual Click here to openIntroduction Wide voltage input DC4 8 30V wide voltage output 0 5 30V can both boost and step down For example if you adjust the output voltage to 18V then the input voltage will change between 5 30V and will output 18V constant For example if you input 12V adjust the potentiometer to set any output of 0 5 30V High power high efficiency and better performance than the XL6009 LM2577 solution It uses an external high power MOS to package large current and high voltage Schottky diodes The current can be set to limit the output current constant current drive battery charging and other occasions It has its own output anti backflow function so you dont need to add anti backflow diode when charging the battery Feature Input voltage 4 8 30VOutput voltage 0 5 30VOutput current can work stably at 3A for a long time and can up to 4A under enhanced heat dissipationOutput power natural heat dissipation 35W enhanced heat dissipation 60WConversion efficiency about 88 Short circuit protection YesWorking frequency 180KHZDimensions 68 x 37 x 22mm L W H mounting aperture 3mmWeight 38 7gPackage includes 3 x Module
