4A BuckBoost Converter Module Adjustable Buck Boost Board With LCD Display

Sepcifications

1. Input voltage range: DC 5.5-30V (when the input voltage is 5V, the boost and buck can be achieved, but the voltage and current measurement is inaccurate; under 4.7V, under-voltage protection will be activated)

2. Output voltage range: DC 0.5-30V

3. Output current: can stably work at 3A for a long time, when enhancing heat dissipation can reach 4A

4. Output power: 35W (natural cooling), when enhancing heat dissipation can reach 50W

5. Voltage display resolution: 0.05V

6. Current display resolution: 0.005A

7. Conversion rate: about 88%
