DROK Voltage Boost Converter, DC 6-30V 5V Step Up to DC 7-32V 12V 24V 5A Adjustable Volt Regulator, LCD Power Supply Module Voltage Current Amp Display Transformer Circuit Board with Case

...ital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work..
General Application --- This voltage step up converter can be used as ordinary step-up module with over-current protection, constant current LED driver module.
Features --- Constant current/voltage mode.
Input reverse connection protection. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF]..
NOTE --- 1). Constant current adjustable means that CC mode only works when the actual load output current is greater than the setting one, otherwise it will work in a constant voltage state, not the current is adjusted to 2A, then it will become 2A for any load being connected. And if the CC value to be adjusted is small, adjust “ADJ-I” counterclockwise a few more times to change. 2). The case is packaged disassembly to avoid damage during transit. It needs to be manually installed..
