20A 300W CC CV Step Down Module Adjustable DC 6-40V to 1.2-36V Voltage Regulator Buck Converter Constant Current Power Supply Module (4pcs)

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
