The input voltage range of the buck converter is DC 6-40V, the adjustable output voltage range is DC 1.2-36V, can be used to convert 24V to 12V 5V, the adjustable output current range is 0-20A, the maximum output power is 300W. The step-down regulator can apply to constant current output. Application: DIY stabilized voltage power supply, LED car display, mobile power supply, industrial equipment appliances, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, etc. Adopting 75V/80A large current dual MOS tube designed step-down board, both input and output use low resistance high frequency electrolytic capacitor, low ripple and stable output. Large 30A current connection screw terminals, more convenient to install Short circuit protection: self-recovery (cannot short circuit for a long time); When both input and output are grounded, CV output constant voltage without load, CC output constant current. color: blue Material: PCB size: 8 x 7 x 3 cm Package Contents: 3 x
