2~24v low voltage input high power 80W boost module Constant voltage constant current with USB 18650 lithium battery
High-power low-voltage input boost module (constant voltage constant current, with USB)
1. Product Highlights:
1.1. Special architecture, support 2V low voltage input, no fear of low voltage, especially suitable for 18650 high power boosting;
2.2. The power is large, the input current can be up to 15A, the output current is 4A; when the input is 3.7V, the output power can reach 45W, and when the input is 12V, the output power can reach 80W;
2.3. Perfect protection mechanism, input anti-anti-burn, input over-current protection, input under-voltage protection, output anti-backflow, constant voltage and constant current, can be directly connected to battery charging;
2.4. High efficiency, dual-stage filtering and low ripple, reliable and stable performance!
2. Product parameters:
Input voltage: 2 ~ 24V
Output voltage: 3 ~ 30V, pay attention to the USB port and the output port directly connected, is the adjustable voltage port 3-30V, not 5V port! ! !
Input current: up to 15A
Output current: Maximum 4A (CC point device is the limit current adjustment potentiometer. When the current limit is reached, the CC indicator lights up and enters the constant current mode; the product is the boost structure. The regulation limit current cannot be directly shorted to the output terminal, but can be counterclockwise first. Adjust to the minimum, turn the clock clockwise and increase the current)
Output power: 3.7V input, maximum 45W; 12V input, maximum power 80W;
Output ripple: two-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: To prevent overdischarge of the lithium battery, please solder the 5.6k resistance resistor at R22 in the lower left corner of the module, starting above 3.5V and stopping below 3V. The factory default works at 2V voltage. If other levels of undervoltage protection threshold are required, 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).
Board size: 80*31.5*20.5mm
Weight: 36g
3. Note:
3.1. This product is a boost structure. The regulation limit current cannot be directly shorted to the output terminal. The CC potentiometer can be adjusted to the minimum counterclockwise. After the battery is connected, it can be rotated clockwise to increase the current.
3.2. This product is a 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.
3.3. Module input IN-disable and output OUT-short, otherwise the constant current function will be invalid.
3.4. Please ensure that the power of the power supply is greater than the power required by the output load. Please reduce the power usage when the module is hot!
3.5.USB output port is not 5V output, directly connected to the output port, the highest adjustable voltage to 30V, such as charging mobile phones or other digital products or compatible with your other valuable instruments, clear the USB output voltage, any damage caused by us Without warranty, we only have the ability to pay for the module and shipping costs. Please read the product description carefully before using it. Damage caused by improper use will not be compensated.
