This step-down voltage module with a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. Wiring is convenient with these large current 30A screw terminals. The buck module has 2 heat sink that could enhance heat dissipation, extending service life. Application: DIY stabilized voltage supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, etc
