Specification:
 
The new upgrade, 5A constant voltage constant current module, can be battery, lithium battery and other charging, with LED indicator, easy to observe the state of charging. Can be used as high power LED driver module, with PWM control input interface and switch machine control interface, easy to use SCM control drive current.Specifications:  
Type: 5A Constant voltage current module
Module properties : non-isolated step down module (BUCK)
Input voltage :4.5-30V
Output voltage: 0.8-30V(continuously adjustable)
Output constant current range: 0.1-5A (Default output :3A)
Output turn lamp current range :0.1-5A (Default turn lamp current :0.3A). There will be a little bit error in the current range because of part parameter differences.
Working temperature: -40~ +85 degree
Working frenquency: 300KHz
PWM control frequency range: 100-300Hz
Transfer efficiency: Maximum 95% (Efficiency is related to the input,output votage,current and voltage differences.)
Short-circuit protection: Yes ( The current limitation is the fixed constant current value.)
Overtemperature protection: Yes ( The output will be automatically cut off once over tempreture occurs.)
Input reverse connection protection : No
Output flow-backwards protection: No ( A space is reserved for the current flowing backward.You can operate it by youself according to the instruction below)
Charging indication: The light is red when charging and green when the electricty is full of .
Installation: 4 pieces of 3mm screws
Connection : Terminal . V-IN is input, V-OUT is output.
Size: 60(L)*26(W)*20(H) mm
Inspection for current is the low-end detaction. please do not connect in/output nagetive directly with wire.
Application：
DIY a stabilized voltage with consistant current, load pretection, short circuit protection when using.
Power supply for your electronic equipments.
Charge for the battery. You can set a different voltage and volume for all the battery when charing,and observe the charging condition.
Solar panels regulator. A solar panel power supply has a perfect protection fuction for the battery .
High power LED drive.
It can be charging for your mobile and digitals as a automotive electronic power supplyMethod for setting voltage, current and indicator:
Set output voltage : according to the value of battery floating voltage or serial/parellel LED voltage, adjust CV potentiometer, set the output voltage to your need. (No load connection)
Set turn lamp current indication : After setting the output voltage, counterclockwise adjust CC potentiometer about 20 laps, use multimeter 20A grade short-circuit output, adjust CC potentiometer to you need turn lamp current, and then adjust turn lamp potentiometer(LED) to just green light.
Set constant current value: after setting the turn lamp current, use multimeter 20A grade still short-circuit output, adjust CC potentiometer to your need current value.
Note: the constant current setting voltage is higher than 0.8V, otherwise the constant current function will fail.
