5A CNC Buck Module DC-DC

1. Input voltage: 6.5-36V (the input voltage is lower than 6.5V, the current accuracy is inaccurate, and the LCD display is abnormal if it is lower than 5.5V)
2. Output voltage: 1.2-32V, the default output is 5V step-down type, the output voltage can only be lower than the input voltage, and the voltage difference is more than 2V
3. Output current: It can work stably at 3.5A for a long time, and it can reach about 4.5A with fan enhanced heat dissipation (adjustable limit current can reach about 4.2-4.5A)
4. Output power: natural heat dissipation 50W (within 3.5A), plus fan to enhance heat dissipation 75W
5. Voltage display: resolution 0.05V, range 1.2-32V
6. Current display: resolution 0.005A, range 0-4.5A
7. Conversion efficiency: about 94%, depending on the voltage difference and current efficiency
8. Working current: about 30mA
9. Input reverse polarity protection: yes
10. Anti-backflow at the output: no (if charging the battery, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; if possible, connect an anti-backflow diode in series with the output positive pole)
11. Short circuit protection: yes
12. Size: about 70.5x48.4x28mm
13. Weight: about 65g
Features:
1. Crystal shell, beautiful design, good touch texture of buttons, and output voltage set by button
2. The button can control the output to turn off and on, and can set the power-on default to ON or OFF
3. LCD can display input and output voltage, output current and output power
4. The input terminal is protected against reverse connection, and the reverse connection will not burn
5. High efficiency, high current, low heat generation, constant current value can be adjusted around 0-4.5A, suitable for office power supply, high-power LED constant current drive, lithium battery charging, etc.
Function Description:
1. There are IN/OUT and ON/OFF buttons on the left si
