Mạch sạc năng lượng mặt trời MPPT 5A.

Mạch sạc năng lượng mặt trời MPPT 5A. - Mạch sạc năng lượng mặt trời / turbine gió. - Dòng vào từ 6-36V - Ổn định dòng sạc đầu ra từ 1.25-32V tùy chỉnh. - Dòng sạc dưới 5A (ví dụ chỉnh output 28v để sạc cho hệ pin 24v . Với mạch này ta có 28v x 5 > đạt 140W. - Hiệu quả MPPT 95% - Có bảo vệ ngắn mạch, bảo vệ nhiệt độ. - Không có bảo vệ ngược cực ở đầu vào và ra. (Nếu mắc sai cực cháy mạch- hãy chú ý) Module parameters: Module name: 5 A buck constant voltage constant current MPPT Module properties: non-isolated step-down module (BUCK) Input voltage: 6-36V Output voltage: 1.25-32V continuously adjustable, (The default output is 5V, if you need other voltages, please explain to the shopkeeper.) 1.25-32V fixed output (for bulk customers) default delivery is adjustable output MPPT voltage setting range: 6-36V Output constant current range: 0.05 -5A long time working current is recommended within 3A Output turning light range: 0.01 -5A Working temperature: - 40~+85 degrees Working frequency: 180KHz Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current, and differential pressure) Short circuit protection: yes (limit current to set constant current value) Over-temperature protection: Yes (automatically shut down the output after over-temperature) Input reverse connection protection: none, (if necessary, please connect a diode in series) Output anti-reverse protection: none, anti-reverse diodes must be added when the output is connected to the battery, otherwise the module will be burned! Remember! The method of setting voltage, current and turning light: (please refer to the illustration above) If the module has no output voltage, please turn the MPPT setting potentiometer clockwise to have voltage output. 1. Set the output voltage: adjust the constant voltage potentiometer (CV) to set the output voltage to the desired voltage according to the floating charge voltage value of the battery you want to charge, or the voltage value of the LEDs after series or parallel connection. (without load) 2. Set the lamp current indication: After setting the output voltage, adjust the CC potentiometer counterclockwise for about 20 turns, use a multimeter with a 20A current gear to short-circuit the output, adjust the CC potentiometer to the current you need to rotate the lamp, and then adjust the rotation Turn on the light potentiometer until the green light just turns on. 3. Set the constant current value: After adjusting the lamp current, the 20A current range of the multimeter is still short-circuit output, (the direct wire short-circuit output with voltage and ammeter can be used ) adjust the CC potentiometer to the current value you need to set. ( When setting the output current by short-circuit method, the actual charging current will be smaller than the short-circuit setting current, which should be because the battery has residual v
