Buck-Boost Converter Module | DC 5-30V to 0.6-30V Adjustable Voltage Regulator | 4A 35W with Display

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
