Features 6V to 40V: The high-power buck converter has a wide input voltage range of 6V to 40V, which can accurately adjust the output voltage and current. The efficiency can be as high as 96%, measured at 20A, converting 24V to 12V. High current dual MOS tube: Constant current power supply module adopts 75V/80A high current dual MOS tube design. The input and output adopt high-frequency low-resistance electrolytic capacitors, with low ripple and stable output. Convenient wiring: High-power buck converter adopts terminal wiring method, it is very convenient to use these high current 30A screw terminals for wiring. The step down voltage module size is 60 x 53 x 27mm / 2.36 x 2.08 x 1.06inch 2 heat sinks: The step down voltage module has 2 heat sinks, which can enhance heat dissipation, make the step down voltage module run more smoothly and last longer Self-healing: Regulator buck converter can self-healing when it is short-circuited, but it cannot be short-circuited for a long time. When the input and output voltages differ greatly, please reduce the power and current. Features: With 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. Regulator buck converter is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. Wiring is convenient with these large current 30A screw terminals. The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current.
