12A constant voltage constant current LCD Digital voltage adjustable current display step-Down power module

12A step-down power supply module (constant voltage constant current LCD display, with crystal shell)

note! ! ! Module default output voltage and current is about 18V / 7A, because the module is a step-down module, you need to reduce the output voltage below the input voltage will work, if you receive the module and found that the output voltage can not be adjusted, Clockwise rotation CV voltage regulator potentiometer 20 laps or more, and then use the module to regulate the voltage; the module for the DC to DC buck module, can not enter the AC, such as transformers; The above problems we do not assume the responsibility and shipping costs, thank you Understanding.

Module default output 18V / 7A or so, the direct short-circuit output current regulation, will have a greater spark prone to danger, it is recommended short output before the first output voltage down to 10V below, CC current potentiometer counter-clockwise Rotate more than 10 turns to the end, and then short the output, turn the CC current adjustment potentiometer clockwise to slowly increase the current value you need.

1. Product highlights:

1.1. Crystal shell, elegant design, touch the touch of good quality;

1.2. Press button to control the output ON / OFF, and you can set the power on default is ON or OFF;

1.3 LCD can display input and output voltage, output current output power;

1.4 input anti-reverse protection, reverse will not burn;

1.5. High efficiency of 95% or more, high current, low heat, the output voltage of 1.2-32V arbitrary regulation, adjustable constant current value 0-12A, suitable for high-power LED constant current drive, battery charging!



2. Product parameters:

Input voltage: 5.3-32V (limit 35V; the lowest input 4V to achieve buck, but less than 5.3V input voltage and current measurements inaccurate)

Output voltage: 1.2-32V (must ensure that the input voltage is higher than the output voltage, the minimum voltage difference between the two is 0.8V)

Output current: long-term stable work in the 8A, strengthen the heat can reach 12A

Output power: Natural cooling 120W (8A or less), to enhance cooling 160W

Voltage display: resolution 0.05V, range 0-32V

Current display: resolution 0.01A, range 0-12A

Conversion efficiency: about 96%

Working current: 25mA or so

Soft start: Yes (very powerful with load module may fail to start)

Input reverse protection: Yes

Output anti-inrush: None (if you charge the battery, the first module to power then the battery, and to ensure that the battery voltage is lower than the output voltage; if the conditions are positive output in series with anti-reflux diode)

Short circuit protection: yes
