Features:
This Constant Current Power Supply Volt Reducer Module with a wide range of input from 6V to 40V,the step-down converter can accurately adjust output voltage and current.
The efficiency max can be up to 95%,measured at 20A,converting 24V to 12V.
The buck converter designed with dual MOS tube of large current 75V / 80A.
Adopt with high frequency low resistance electrolytic capacitor for input and output use,low ripple, stable output.
Board mounted 2 heat sink,enhance dissipation function for the step dowm module.
Wiring is convenient with these large current 30A screw terminals. 
When there is a big difference between input and output voltage,please decrease power and current.
