converter input voltage range is DC 6-40V, adjustable output voltage range is DC 1.2-36V, can be used to convert 24v to 12v 5v, adjustable output current range is 0-20A, max output power is 300W. The regulator can apply to constant output current.Application: DIY stabilized voltage supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, etcAdopting 75V / 80A current dual MOS tube designed step-down board, Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. current 30A connection screw terminals, more convenient to installShort Circuit Protection: Self-(cannot short circuit for long time) ;When input and output is common grounded, no-load CV output constant voltage, CC output constant current.colour:BlueMaterial:PCBsize:8 x 7 x 3cmPackage Contents:1 x Adjustable DC ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
