Adjustable Power Supply Module DC-DC CC CV Buck Converter Step-down Power Module 7-32V To 0.8-28V 12A 300W



- 1. Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module
- 2. Input voltage: DC 7-32V
- 3. Output voltage:DC 0.8-28V continuously adjustable
- 4. Output Current: 9A 12A (when power tube\'s temperature exceeds 65 degrees, please add cooling fan)
- 5. Constant current range: 0.2-12A ( adjustable )
- 6. Turn lamp current: constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A).
- 7. Lowest pressure: 1V
- 8. Output Power: Maximum power is about 300W
- 9. Conversion efficiency: up to about 95%
- 10. Operating frequency: 300KHZ
- 11. Output ripple: 20M bandwidth
- 12. Input 24V Output 12V 5A ripple around 50mV (Excluding noise)
- 13. Output short circuit for protection : Yes, constant current
- 14. Input Reverse Polarity for Protection: None
- 15. Output prevent backflow: None
- 16. Wiring: Terminal
- 17. No-load current: Typical 20mA (24V switch 12V)
- 18. Load regulation: ± 1% ( constant )
- 19. Voltage regulation: ± 1%
- 20. Dynamic response speed: 5% 200uS
- 21. Potentiometer adjustment direction: clockwise (increase) , counterclockwise (decrease). the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)
- 22. Operating temperature: Industrial grade (-40 °c to +85 °c) ( please note the actual use of the power tube temperature , high temperature heat strengthened please )
- 23. Indicator: dual color indicator, charging indicator light is red, the green light means fully charged ( No load is green )
