1. Support 2V low voltage input, no fear of low voltage, especially suitable for 18650 high-power boost;
2. High power, the maximum input current can reach 15A, the output current is 4A; when 3.7V input, the output power can reach 45W, when 12V input, the output power can reach 80W;
3. Perfect protection mechanism, input reverse anti-burning, input over-current protection, input under-voltage protection, output anti-backflow, constant voltage and constant current, can be directly connected to the battery for charging;
4. High efficiency, dual-stage filtering and low ripple, reliable and stable performance!
Parameters:
Input voltage: 2 ~ 24V
Output voltage: 3 ~ 30V. Note that the USB port is directly connected to the output port. It is an adjustable voltage port 3-30V, not a 5V port!
Input current: Maximum 15A
Output current: Maximum 4A (CC point potentiometer is a current-limiting adjustment potentiometer. When the limit current is reached, the CC indicator light is on and enters the constant current mode; BOOST boost structure, adjust the limit current and can not directly short the output terminal, you can adjust it counterclockwise first To the minimum, turn clockwise to increase the current after connecting the battery)
Output power: under 3.7V input, the maximum power is 45W; under 12V input, the maximum power is 80W;
Output ripple: dual-stage filtering, low ripple output!
Conversion efficiency: 82~95%
Input overcurrent protection: 15A fuse
Input anti-reverse protection: high efficiency MOS type
Input undervoltage protection: If you need to prevent the lithium battery from over-discharging, please weld a 5.6k resistance at R22 at the lower left corner of the module. It will start when it is higher than 3.5V and stop when it is lower than 3V. The factory defaults to work at 2V voltage. If you need other levels of undervoltage protection threshold, you can calculate it yourself or contact customer service. The calculation formula is R22=12500/(U-0.75v) ohm, where U is the desired undervoltage protection threshold voltage (stop Voltage).
Note:
1. BOOST boost structure, adjust the current limit and can not directly short-circuit the output terminal. You can first adjust the CC potentiometer to the minimum counterclockwise, and then turn the battery clockwise to increase the current.
2. BOOST boost structure, the minimum output voltage is approximately equal to the input voltage, so the output current cannot be set from 0, the minimum output current is approximately the input voltage divided by the load resistance value.
3. Module input IN- must not be short-circuited with output OUT-, otherwise the constant current function will fail.
4. Please make sure that the power of the power supply is always greater than the power required by the output load. Please reduce the power when the module is severely hot!
5. The USB output port is not a 5V output. It is directly connected to the output port. The maximum voltage can be adjusted to 30V. For example, to charge mobile phones and other digital products or compatible with your other valuable instruments, please verify the USB output voltage first.
