  • Applications:

  • Notes:The IN- above the module (input negative), IN+ (input positive), OUT- (output negative), OUT+ (output positive) must be correct, otherwise the module may cause damage to the module.


  • 1.As a battery charger

  • Module without constant function can not be used to charge the battery , because the complete consumption of battery charger great pressure, leading the charge current is too large , causing damage to the battery , so when the battery begins to use a constant current charging when the charge to a certain extent, when to automatically switch back to the constant voltage charging .
  • Usage:
  • (1) ( 1 ) Make sure you need to charge the battery float voltage and charging current ;
  • (2)Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.
  • (3) use the multimeter (10A) to measure the short circuit current, and adjust the constant current.potentiometer to make the output current reach the predetermined charge current value.
  • (4)recharge the light current by default to 0.1 times the charge current (constant current value).
  • (5)to adjust the output voltage of the constant voltage potentiometer to float voltage;
  • (6)battery, test charge.
  • (1, 2, 3, 4, 5 steps for module input power supply, output no-load non battery.)

  • 2.Use as a normal buck modules with over-current protection capabilities
  • (1)determine that you need to drive the LED's working current and. High working voltage;
  • (2)adjust the constant voltage potentiometer to adjust the output voltage to about 5V.
  • (3)use the multimeter (10A) current gauge to measure the short circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED working current.
  • (4)constant voltage potentiometer makes the output voltage reach LED. high working voltage.
  • (5) LED, test machine.
  • (1, 2, 3, 4 steps for module input power supply, output no-load no LED lamp.)
  • Note: This module is more than 5A in use, to enhance heat dissipation ! ! !
