80W Boost Converter Module CV CC Step Up Module with USB Port 2-24V to 3-30V

80W Boost Converter Module CV CC Step Up Module with USB Port 2-24V to 3-30V

Features:
- Special architecture supports 2V low voltage input, no fear of low voltage. Especially suitable for 18650 high power boost.
- High power. The maximum input current is 15A and output current is 4A. With 3.7V input, output power can reach 45W. With 12V input, output power can reach 80W.
- Perfect protection mechanism, namely input reverse connection protection, input over-current protection, input under-voltage protection, and output anti-backflow. With constant voltage and constant current, it can be directly connected to battery to charge.
- High efficiency, double-stage filtering and low ripple, reliable and stable performance.

Specifications:
- Input voltage: 2 ~ 24V
- Output voltage: 3 ~ 30V. Attention: USB port is directly connected to the output port. It is an adjustable voltage port 3-30V, not a 5V port.
- Input current: 15A maximum
- Output current: Maximum 4A (CC potentiometer is a current limiting potentiometer. When limit current is reached, CC indicator is lit and enters constant current mode. With BOOST structure, regulating current cannot be short-circuited directly to the output terminal. It can be adjusted counterclockwise first to the minimum. After connecting battery, turn it clockwise to increase current)
- Output power: 45W at 3.7V input; 80W at 12V input
- Output ripple: double-stage filtering, low ripple output
- Conversion efficiency: 82 ~ 95%
- Input over-current protection: 15A fuse
- Input reverse connection protection: high efficiency MOS type
- Input under-voltage protection: In order to prevent lithium battery from over-discharging, please solder a 5.6k resistance resistor at the lower left corner of the module, R22. It will start when it is higher than 3.5V and stop when it is lower than 3V. Factory default operation is 2V. If you need other levels of under-voltage protection threshold, you can calculate it yourself or contact customer service. Its calculation formula is R22 = 12500 / (U-0.75v)Ω. Where U is the desired under-voltage protection threshold voltage (stop voltage).
- Board size: 80 * 31.5 * 20.5mm
- Weight: 36g

Precautions:
1. With BOOST boost structure, regulated current cannot be short-circuited directly to the output terminal. You can first turn CC potentiometer to the minimum counterclockwise. After connecting battery, turn it clockwise to increase current.
2. With BOOST boost structure, the minimum output voltage is approximately equal to input voltage. So output current cannot be set from 0. The minimum output current is about input voltage divided by load resistance.
3. The input IN- of the module is forbidden to be short-circuited with the output OUT-, otherwise constant current function is invalid.
4. Make sure that the power of power supply is greater than the power required by an output load. When the module is hot, please reduce the power.
5. USB output port is not a 5V output and is directly connected to output port. The maximum adjustable voltage is 30V. If you want to charge digital products such as mobile phones or be compatible with your other valuable instruments, please verify its USB output voltage first. Please read the product description carefully before using.
