12V24V To 5V9V 12A High Power Step-Down Power Supply LED Constant Current Module(12KX)

Description

1. Input voltage: 5.3-32V (4V can be input to achieve step-down (min), but the voltage and current measurement is correct when the input is below 5.3V)
2. Output voltage: 1.2-32V (must ensure that the input voltage is higher than the output voltage, the difference between the two is 0.8V)
3. Output current: can work steadily at 8A for a long time, can reach 12A with enhanced heat dissipation
4. Output power: 120W (within 8A) with natural heat dissipation, 160W with enhanced heat dissipation
5. Voltage display: resolution 0.05V, range 0-32V
6. Current display: resolution 0.01A, range 0-12A
7. Conversion efficiency: 96 percent or so
8. Operating current: 25mA or so
9. Crystal shell, beautiful and elegant design, good touch texture of keys
10. Key can control the output off and on, and can set the power on default to ON or OFF
11. LCD can display input and output voltage, output current and output power
12. Input anti-reverse connection protection, reverse connection will not be burned
13. High efficiency of more than 95 percent, high current, small heat, output voltage 1.2-32V arbitrary adjustment, constant current value 0-12A adjustable, suitable for high-power LED constant current drive, lithium battery charging, etc.
14. Size: 82x52x32mm
15. Weight: 80g

Attention:
1. The module factory default output voltage and current is about 18V/7A, because the module is a buck module, you need to adjust the output voltage down to the input voltage below to work, if you receive the module found that the output voltage can not be adjusted, please first counterclockwise rotation of the CV voltage adjustment potentiometer more than 20 turns, and then use the module can be normally adjusted voltage; module for DC/DC direct current to DC buck module. The module is a DCDC direct current to DC step-down module and cannot be fed with transformer direct step-down AC power.
2. If you are charging a battery, you need to put a diode in series with the positive terminal of the output to prevent backflow, otherwise the battery will be easily damaged by backflow; if the current and power are too large, please strengthen the heat dissipation or pay attention to the temperature of the heat sink to prevent burning.
