3 String Lithium Iron Phosphate Lithium Battery Charger Board MPPT Solar Controller CN3722
Description:
12V (10.8 11.1V) full of junction voltage 12.6V lithium battery
3 string lithium battery charging management
The maximum power point tracking (MPPT) solar cells
Maximal power point tracking (MPPT) is to ensure that the changes in light intensity, maximum output power of photovoltaic cells has been, in order to make full use of solar energy. In general, the need to achieve MPPT function with a switch mode DC-DC converter, product keep the output voltage and charging current (maximum output power).
CN3722 is a step-down switch mode DC-DC converter the photovoltaic maximum power point tracking function, the input voltage up to 25V, is very suitable for the input voltage and the voltage of the battery is used relatively large.
Charging management board characteristics:
- High-end technology of maximum power point tracking MPPT solar energy charging management chip, with a trickle, constant current and constant voltage charging management
- High frequency low conduction resistance of double MOS tube, high current diode, high efficient flat power inductor current sensing resistor, Kang Tong
- Intelligent temperature control cooling system, automatic detection of charging management board temperature and open the radiator (need to reprovision external radiator)
- Charging speed and efficiency and less heat, speed
- Double status indicator, not connected with the battery when the red light green light lit, charging when the red light, green light and full auto stop
