Application scope:

This module can be used in the fields of large input voltage fluctuation and stable output requirements. For example:

1. 12V storage battery (10-14v) can output 12V to supply power to 12V equipment, and 24V storage battery can be used as vehicle power supply

2. Solar panel voltage, solar panel voltage fluctuation is relatively large, this module can output voltage, power supply to the equipment or charge the battery.

3. Drive high-power LED lights, constant current drive, such as 12V battery drive 4 series of LED lights, at this time, the voltage difference between LED and battery is small.

Output current regulation method:

1. Adjust CV potentiometer, according to your load requirements, set the output voltage to the voltage value you need.

2. Set CC potentiometer about 30 turns counter clockwise (that is, set the output current to the minimum), connect led, and adjust CC potentiometer to the current you need. For battery charging, after discharging the battery, connect it to the output and adjust CC to the current you need. (for charging, it must be adjusted with the discharged battery, because the more power left in the battery, the smaller the charging current.) Please do not adjust the current by short circuit. The circuit structure of the module cannot be adjusted by short circuit.
