Data Reference:input voltage range is DC 5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current can be 3A for long term , if enhance heat dissipation, it can reach 4A; max output is 35W, if enhance dissipation, it can reach 50WSafe Protection: the module is with Anti-reverse connection protection of input end, so it will not burn out when there is reverse connection.Anti-backflow protection at the output end. No need to anti-backflow diode when charging. Multiple software protection mechanisms are available, and the protection is adjustable. When the working parameters of the module the protection , the output will be automatically turned offGood Thermal PerformanceE:Output ripple is small and filter is available.Thick heat sink .-boost IntegratedLCD Displays: input/output voltage, output current/output /output capacity/output time.The module can be set to ON/OFF by default.Wide Range of Applications: the volt conversion board can be used as an ordinary /Boost module with over-current protection; used as a high- LED constant current driver module; DIY a solar controller, Battery Charging.Material: Metal+ABScolour: BlackPackage Contents:1 x voltage regulatorOnly the above package content, other products are not included.Note: Light reflection and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
