Designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. This step-down voltage module has a wide input voltage range from 6V to 40V; the step-down converter can accurately adjust output voltage and current. 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 sinks that could enhance heat dissipation, extending service life. When there is a big difference between input and output voltage, please decrease power and current. Applications: Motors, audio, monitor, LED car display, air conditioner, fans, solar energy, photovoltaic energy, DVD, LED lights, pumps, industrial equipment appliances, etc
