Product Description
Description
  • Module Name:8A Constant Current Buck
  • Module Properties: non-isolated step-down module (BUCK)
  • Input Voltage:7~40V
  • Output voltage:1.25~36V(adjustable)
  • Output current:0~8A(80w)
  • Turn light current:constant current value *0.1 (Such as the constant current value is 3A ,turn light current is set to constant current of 0.1 times(0.1*3A=0.3A)
  • Working temperature: -40 to +85 degrees
  • Conversion efficiency:up to 95% (efficiency is related with input voltate,output voltage,current and voltage difference)
  • Operating frequency: 180KHz
  • With overheat, overcurrent,and input reverse polarity protection
  • Short-circuit protection: YES (please try not to short-circuit )
  • Output protection against anti-irrigation:NO
  • Charging(turn lights)indication:YES (charging green ,full charged blue,constant current red )
  • Connection mode:Large current terminal,needn't solder
  • IN+: input positive
  • IN- : input negative
  • OUT+: output positive
  • OUT-: output negative
  • Size:70*39*31 mm
 
 
 
 
 
Applications:
  • High-power LED constant current driver ;
  • The power supply for your electronic device(laptop, PDA or the other digital products), according to your system can set the output voltage value;
  • Charge for the battery, lithium batteries etc.
  • Driving high power LED lamp. 
Battery charging method:
1.Make sure of the required battery float voltage and charging current , the input voltage of the module.
 
2.Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
 
3.Use the multimeter in 20A current scale to measure output short-circuit current,and adjust the current potentiometer to make sure the output current to the expected charging current value.
 
4.Adjust the constant voltage potentiometer make the output voltage reaches the float voltage;
 
5.Connected to the battery, try to charge.
 
(1,2,3,4 steps to connect the power module input,output no-load does not connect battery.)
 
 
 
LED constant current drive Usage:
1.Make sure LED current and the maximum operating Voltage;
2.Adjust the constant voltage potentiometer,and adjust the output voltage to about 3V.
 
3.Use the multimeter in 20A current scale to measure output short-circuit current,and adjust the current potentiometer to make sure the output current to the expected LED operating current.
 
4.Adjust constant voltage potentiometer make the output voltage reach the maximum LED operating voltage.
 
5.Connect LED, test.
 
(1,2,3,4 steps to connect the power module input, output No-load does not connect LED.)
 
 
 
 
 
 
 
Package included:
 
  • 1 x DC buck converter module 8A
