1. Module properties: synchronous rectification non-isolated buck constant current constant voltage module CC CV charging module
2. Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind turbines
3. Input voltage: 6-40VDC
4. Output voltage: continuously adjustable (1.2-35VDC) below 32V for a long time (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted)
5. Output current: maximum 20A, long-term within 15A (please add a fan to dissipate heat when the power tube temperature exceeds 65 degrees, and use a reduced rating for high voltage output)
6. Current limiting range: 0.2-20A (adjustment) please add a fan if the module exceeds 65 degrees
7. Low voltage difference: 3V
8. Operating frequency: 150KHZ
9. Conversion efficiency: about 96% high, efficiency is related to voltage difference and use environment
10. Output ripple: ripple about 50mV (excluding noise) 20M bandwidth (for reference only) input 24V measured
11. Working temperature: -10 to +75 degrees Celsius (please pay attention to the power tube temperature in actual use, if the temperature is too high, please increase heat dissipation or use it at a reduced rating)
12. Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
13. Output short circuit protection: yes (instantaneous protection) constant current (the current constant current value cannot be short-circuited for a long time)
14. Input reverse connection protection: no
15. Output anti-reverse current: no, for loads with self-power or inductive loads, an external diode is required!
16. Wiring method: Wiring terminal
17. Size: 60x53x30mm
18. Weight: about 85 grams

Output current adjustment method:
1. Adjust the CV potentiometer to set the output voltage to the voltage value you need according to your load requirements
2. Set the CC potentiometer counterclockwise for about 30 turns (that is, set the output current to a small value), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, discharge the battery, then connect it to the output, and adjust CC to the current you need (when used for charging, you must use a discharged battery to adjust it accurately, because the more power left in the battery, the smaller the charging current)
