2. Adopt imported high frequency low conduction internal resistance double MOS tube, high current diode, high efficiency flat high power inductor, Kang copper current detection resistance

3. Intelligent temperature control cooling system automatically detects the temperature of the charging management board and turns on the radiator (Additional radiator needs to be reprovisioned)

4 high speed and efficient charging method, small heat, fast

5. Dual status indicator, when the battery is not connected, the red light is always on, the red light is on when charging, and the green light is on

Basic parameters:

Input voltage: 18V solar panel

Output voltage: 2-4 series lithium battery or lithium iron phosphate battery (adjustable by external resistor) Please inform the output voltage when shooting

Output current: 3A

Wiring method: pad

IN+ input positive, IN- input negative

BAT+ positive battery, BAT- negative battery

Size: 30*50mm

Adjustable resistance adjusts output voltage

Suitable for 2-4 string lithium battery or lithium iron phosphate battery

Lithium battery 4.2*2 string = 8.4V

Lithium battery 4.2V*3 string = 12.6V / 4.2V*4 string = 16.8V

Lithium-Ion battery 3.6V*3 string=10.8V / 3.6V*4 string=14.4V

The no-load voltage at the time of adjustment is recommended to be lower than the actual charge termination voltage 0.1V (eg 4.2V*3 string = 12.6V set to 12.5V) because the voltage will automatically exceed the set no-load voltage when the charge is terminated.

Solar Battery Maximum Power Point Tracking (MPPT)

The maximum power point tracking (MPPT) of the solar cell is to ensure that the photovoltaic cell always outputs the maximum power in order to fully utilize the solar energy when the light intensity changes. In the general case, the MPPT function needs to be implemented with a switch mode DC-DC converter to maximize the product (output power) of the output voltage and the charging current.

CN3722 adopts the switching step-down mode DC-DC conversion to realize the maximum power point tracking function of photovoltaic cells. Its input voltage can reach up to 25V, which is very suitable for applications with large difference between input voltage and battery voltage.
