This module has Constant current and Pressure limiting function. Can be used as adjustable step-down power module, but also as a charging module. Simply limit the set output current (to replace the resistance of the R1R2 can change the output current)
Note: This module is buck module, the input voltage must higher 1.5V than output voltage, to ensure the output voltage stable. In the larger current work status, If you feel the board is very hot, it should install the heat sink,
- Car power supply:
- Very simple and convenient for charging your mobile phones, MP3, MP4 etc.
- Step-down charger:
- This module has Constant current and Pressure limiting function. Can be used as adjustable step-down power module, but also as a charging module. Replacement of the resistance of the R1R2 can change the output current, can Charge Lead-acid batteries, lithium batteries.
- Power supply for your electronic equipment:
- step-down 12V or 24V battery to 3-22V
- 1x DC-DC Converter
