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.
