CNC Buck-Boost Module Constant Voltage and Constant Current 12V Boost 9V24V Adjustable Buck Boost Solar ChargingItem NO.: MK02071

CNC Buck Boost Module

Product Highlights:

1. CNC adjustable voltage and current, convenient and fast, industrial quality, high precision, and can be directly used in engineering projects;

2. Adopting a professional power LCD, with a clear interface and minimalist operation, it has a nearly perfect protection mechanism;

3. Hardware protection: Input end anti reverse connection protection, reverse connection does not burn; Short circuit protection at the output end, short circuiting without burning; The output end is anti backflow, and there is no need to add an anti backflow diode when charging the battery;

4. Software protection: Over voltage protection (OTP), Over current protection (OCP), Over power protection (OPP), Over temperature protection (OTP), Input Under voltage protection (LVP);

5. Default adjustable voltage or constant current value can be set, which can be quickly adjusted in various applications;

6. Voltage and current can be locked to prevent misoperation!

7. Full use of materials, stable performance, and wide range of applications.

Product Parameters:

● Input voltage: DC5.0V-30V (with undervoltage protection LVP below 4.7V, it is recommended to use an input voltage above 7V. When the input voltage is below 7V, the output power will decrease. The lower the input voltage, the smaller the output power)

● Output voltage: DC0.6V-30V

● Output current: 0-4.0A

● Output power: 35W under natural heat dissipation, up to 50W with air cooling

● Voltage accuracy: ± 0.5%+1 words, resolution: 0.01V, factory calibrated accuracy

● Current accuracy: ± 0.8%+3 words, resolution: 0.001A, factory calibrated accuracy

● Conversion efficiency: around 88%

● Soft start: Yes

● Input reverse protection: Yes, reverse connection does not burn

● Output end anti backflow: Yes, it can be directly connected to the battery

● Output short circuit protection: Yes, the output terminal can be directly short circuited

● Temperature protection (OTP): Yes, 100 ℃

● Operating frequency: 180KHZ

Key Description:

● Short press the UP/DOWN button to adjust the voltage by default, and support long press (fast increase/decrease);

● Press and hold the SET button for 1 second to adjust the constant current value (current limit value);

● When adjusting the voltage, SET and CV flash, and when adjusting the current, SET and CC flash, which is very intuitive;

● Short press the SET button to switch between displaying current A/power W/capacity Ah/energy Wh/time h;

● Short press the ON/OFF button to turn on/off the power output;

● Press and hold the ON/OFF button for 2 seconds to switch between displaying input and output voltages.

● After setting it to CC, the constant current value is adjusted by default. When driving the LED, fast dimming can be achieved by rotating the encoder, which is very convenient!

● Press and hold the SET button for 3 seconds to enter the setting interface;

● Note: After product protection, the output will be turned off, and the LCD will display the corresponding protection code (LVP/OVP/OCP/OPP/OAH/OPH/OHP). The power chip itself also comes with various protections. If the chip itself is protected, OEP will be displayed
