Product Review

Feature:
Module Name: 20A 300W DC Step Down Buck Converter
Input Voltage: DC 6-40V, Optimum input voltage 10-40V
Output Voltage: DC 1.2-35V ( continuously adjustable ), Recommended below 32V for long time work
Minimum Voltage Difference: 3V, output voltage should be lower than input voltage
Output Current: 20A (max), Recommended below 15A for long time work
Constant Current Range: 0.2-20A ( continuously adjustable )
Transfer Efficiency: 96% (MAX)
Output Ripple: About 50mV
Switching Frequency: 150KHz
Work Temperature: -40 degree to + 75 degree Celsius, please strengthen the heat dissipation or reduce the value if exceeds 65 degree.
CV Potentiometer: Increase voltage clockwise, decrease voltage counterclockwise
CC Potentiometer: Increase current clockwise, decrease current counterclockwise
Output Short-circuit Protection: Yes, (Instantaneous protection) Constant Current (The current constant current value should not short-circuit for a long time)
Output Anti-Perfusion: NO, For load with built-in electric or inductive negative load requires additional diodes
Connection Mode: Terminals
Module Size: 60x53x27mm/2.36x2.08x1.06 inch

Output voltage/current regulation method:
1. Adjust CV potentiometer according to your battery or LED, and set the output voltage to the value you need.
2. Turn the CC potentiometer clockwise for about 30 turns, set the output current to the minimum, connect the LED, and adjust the CC potentiometer to the current you need. If it is used for battery charging, after the battery is discharged, then connect to the output, and adjust CC potentiometer to the current you need. (the more residual battery power, the lower charging current).

Package Include:
1pcs 20A 300W DC Step Down Constant Voltage Constant Current Buck Converter
