300W 20A Constant Current DC DC Step down Buck Converter with LED Driver
DC-DC buck converter step-down module
Wide input voltage range from 6-40 V, the step-down converter can accurately adjust output voltage and current.
Efficiency up to 96%, measured at 20 A, converting 24 V to 12 V
It is designed with 75 V / 80 A current dual MOS tube.
Input and output use high frequency low resistance electrolytic capacitor for stable output.
Large current 30 A screw terminals
The buck module has 2 heat sinks for enhanced heat dissipation.
When large input and output voltage occurs, please decrease power and current.

VO+: Output positive
VO-: Output negative
+IN: Input positive
-IN: Input negative
CV: Output voltage adjustment
CC: Output current adjustment
EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
When input and output is common grounded, no-load CV output constant voltage,CC output constant current
