Applications Of MPPT Solar Panel Controller 5A DC-DC Step-down CC/CV Charging Module Display LED

• It can support high-power LED.

• It can power supply for electronic devices.

• For a variety of battery charge, can observe the state of charge.

• As a car power supply , it can for your cell phone or digital products supply.

• DIY a voltage Regulator, with constant current function, Short-circuit proof, can protect the load.

• Charger for all kinds of batteries, with MPPT function, can enhance the charging current to double. With a constant current and prevents battery overcharge, effective protection of the battery.

Note : The module's current detection is low-end detection. Please do not short the input negative and output negative directly with wire.

1. Set the output voltage: according to the battery you want to charge the float voltage, or string, parallel to the LED voltage, adjust the constant voltage potentiometer (CV), the output voltage is set to the required voltage. (Without load)
2. set the turn light current instructions: set the output voltage, the CC potentiometer counterclockwise 20 laps or so, with a multimeter 20A current file short-circuit output, adjust the CC potentiometer to you need to turn the lamp current, Light electric potentiometer, transferred to just light green so far.
3. Set a constant current value: tune the turn-on lamp current, the multimeter 20A current file is still short-circuit output, (with voltage, ammeter direct wire short-circuit output can) adjust the CC potentiometer to the current value you need to set. (When using the short-circuit method to set the output current, the actual charging current will be smaller than the short-circuit setting current, the battery should have the remaining voltage, if you want to set the exact charging current, please use the battery connected to the output And then set the output current.) Note: constant current set when the voltage is higher than 1.25V, otherwise the constant current function will be invalid.
4. set the MPPT voltage:

• with adjustable power supply set method: the adjustable power supply to set the voltage value (such as 18V), the output is not connected to the load, the module has an output voltage, counterclockwise MPPT Set the potentiometer to the output voltage just lower the critical point can be.
  
• with the solar panel directly set the method: input directly connected to the solar panels, according to the load set the output voltage, shade in the solar panels on the part of the light, the output load. Multimeter to measure the output voltage of the solar panel (with the voltage meter cut to the input voltage display), adjust the MPPT potentiometer to the solar panel voltage to the maximum power point voltage so far. (Solar panels actually the maximum power point voltage will be lower than the nominal voltage, such as 18V solar panels, the maximum power point will be about 17.5V)
