Using the tutorial: 1. Plugged into a power supply (3-40 v), the power indicator light is lit, the module to work properly. 2. Adjust the blue potentiometer knob (generally booster clockwise, counterclockwise step-down) with a multimeter monitoring the output voltage to the voltage.

Description

Input voltage: 7-35V Output voltage: 1.25-30V adjustable Dropout voltage: input voltage must be higher than output voltage of 2V Output current: 0-3A, 3A maximum Output power: 15W(If the temperature is high, please strengthen heat dissipation) Conversion efficiency: 92% maximum (the higher the output voltage, the higher the efficiency) Turn lamp current: constant current value * (1% -100%), turn lamp current and constant current value linkage, such as constant current value is 3A, turn the lamp current is set to 0.1 times that of the constant current (0.1 * 3 A = 0.1A), when the value of the constant current regulation into 2A, turn lamp current is 0.1 times that of the constant current (0.1 * 2A = 0.2A). The default shipment has to adjust to the 0.1 times Indicator light: constant current cc indicator light red, charging indicator light red, full-charged indicator light blue The output ripple: 20M bandwidth (for reference only) Input 12V output 5V 3A 60mV (MAX) Working temperature: industrial grade (- 40 -- + 85 celsius degree) (when temperature is more than 40 degrees, please reduce power, or enhance heat dissipation) Full load temperature rise: 45 celsius degree No-load current: 10mA typical (12V to 4.2V) Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Output short circuit protection: yes, constant current (current setting constant current value) Connection mode: can lead directly welding on the PCB
