Specification: Module Properties: non-isolated synchronous rectification automatic boost/buck converter moduleInput voltage: DC 5V-30VInput current: 8A (MAX), Peak 10A (6A work for long time working)Static current: 4mA (different operating voltage the static current maybe have a little error)Output voltage: 1.25V-30V(continuously adjustable)Output Current: 10A (MAX) (natural cooling 5A for long time working)Output constant current range: 0.2A-10AOutput power: Long time working 50W, the max can up to 100W, please make allowance to use.Working temperature: -40 -85Operating frequency: 150KHzConversion efficiency: typically 91% (12V to 12V 5A), the MAX 93%Overcurrent protection: YesShort circuit protection: Yes (current-limiting protection)Overtemperature protection: (automatically reduce the output voltage after overtemperature)Input reverse polarity protection: None, (if necessary, install diode at input port)Output prevent backflow : Yes, no need to add prevent backflow diode for charging .Connect method: terminals, (IN is the input, OUT is the output)Size: 60mm * 53mm * 22mm (L*W*H)Application:A regulated power supply.Solar panels regulator.Charge for the battery.Drive high-power LED.Power supply for your electronic device.Output current adjustment method:1.Adjust CV potentiometer, according to your battery or LED, set the output voltage value to your need.2.Counterclockwise adjust CC potentiometer about 30 laps, make the output current in the minimum. Connect the LED, adjust CC potentiometer to the desired current. If charge for the battery, the battery should fully discharge at the first, then connected to the output, adjust CC potentiometer to desired current. (Must use completely discharged battery to set, otherwise inaccurate. Because the more battery power remain, the smaller the charge current. ) Please do not use short-circuit way to adjust current, because special circuit structure of the boost converter can not adjust in that way. Package Included:1 X DC-DC Module
