amiciSmart Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 3A 35W Power Supply Module

Button/Potentiometer/LED introduction:
1.ON/OFF Button: Short Press to select whether output . Long press (more than 3second) to restore default settings.
2. IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press to switch display output current or output power.
3. CV Potentiometer: Adjust output voltage. clockwise?Increasing.
4. CC Potentiometer: Adjust output current. clockwise?Increasing.
5. ON LED: Green LED, Output indicator.
6.CC LED: Red LED, Constant current output indicator. when the load current reaches the set current , CC indicator will turns ON.

Parameters:
Input voltage range: DC 5.5-30V
Output voltage range: DC 0.5-30V
Output current: 0-3A (natural cooling), Max.4A (enhance heat dissipation)
Output power: 35W (natural cooling), Max.50w (enhance heat dissipation)
Voltage display resolution: 0.05V
Current display resolution: 0.005A
Conversion rate: about 88%
Soft start: Yes, (a large power load module may fail when it is started)
Working frequency: 180KHZ

Protection:Input reverse connection protection, Output stop the current from feeding back protection,Output short circuit protection, Input undervoltage protection.
The diameter of mounting hole: 4mm
Attention?
1.IN- and OUT- must not be short circuit, otherwise the CC function will be invalid.
2. Please ensure that the power of the power supply is greater than the power required by the output load!
3.The input voltage should be over 8V ,if Full-load output .
4.when the input voltage is 5V, you can normally achieve buck-boost, but the voltage and current measurement is inaccurate; less than 4.7V, under voltage protection will be activated

• Buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, output current range is 0-3A, with enhance heat dissipation, it can reach 4A; max output power is 35W, with enhance dissipation, it can reach 50W.
• LCD Display: the voltage regulator module is designed with LCD, can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A.
• Application: power supply with over-current protection，power conversion， LED constant current driver module，bilge pump, 12v lead acid battery, Drone, folding solar panel, air matress pump, LED strip, power some small 5V to 12V, 15V CPAP machine,test meter, circuit test, solar project
• Safe Protection: with reverse connection protection at input and with anti-backflow at output terminal, so there is no need to add an anti-backflow diode when charging the battery.
• ON/OFF Button: Short Press to select whether output . Long press (more than 3second) is used to restore default settings.IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press is used to switch display output current or output power.
