Product details

20A 300W Rectification Power Supply Step-down Module

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 potentiomet
