DC-DC Buck Converter 4.5-30V to 0.8-30V 5A Module Solar Battery Charger LED Driver with PWM Description Specification: Item name: 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 equicments. Charge for the battery. You can set a different voltage and volume for all the battery when charing,and observe the charing condition. Solar panels regulator. A solar panel power supply has a perfect protection fuction for the battery . High power LED drive. It can be charding for your mobile and digitals as a automotive electronic power supply Direction for setting voltage,current and turn lamp:( Please check the picture above ) 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. Attention: It is invalid that the voltage must be higher than 0.8V when setting current. Package included: 1 x DC-DC Buck Converter 4.5-30V to 0.8-30V 5A Payment We only accept PayPal.
