Precise Button-Controlled Adjustment – No potentiometer required! Easily fine-tune voltage using intuitive buttons for more precise control and hassle-free operation.
Step-Up & Step-Down Conversion – Supports both boost and buck functions, allowing seamless voltage regulation from DC 5V~30V input to DC 0.65V~30V output, perfect for versatile applications. Max output power is 35W, with enhance dissipation, it can reach 50W.
Smart LCD Display – Real-time monitoring of input and output voltage, output current and output power, making it ideal for lab testing, DIY electronics, and power management.
CC & CV Modes – Features constant voltage (CV) and constant current (CC) regulation, making it suitable for battery charging, LED drivers, and solar charging setups.
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 batter
Note: Its recommended that the input voltage should be higher than 7V.
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. ON LED: Green LED, Output indicator.
4.CC LED: Red LED, Constant current output indicator. when the load current reaches the set current , CC indicator will turns ON.

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
Package Includes:
1 xBuck Boost Converter Display, Buck-Boost Board DC 5-30V to DC 0.6-30V Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module
