DC-DC Buck-Boost Converter, 5.5-30V to 0.5-30V, 4A 35W, Adjustable with LCD Display

1. Buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current range is 0-4A, can be arbitrary adjustable, if enhance heat dissipation, it can reach 4A; max output power is 35W, output 3A 35W for long time stable work, if enhance dissipation, it can reach 50W. 2. Button control: Short press IN/OUT to switch input and output voltage, long press to switch output current power. Short press ON/OFF to control output ON or OFF, long press to set the default output state ON or OFF. 3. The voltage regulator module adopts LCD design, can switch display input voltage, output voltage, output current, output power; voltage display resolution is 0.05V, current display resolution is 0.005A. 4. The liquid crystal can display the input and output voltage and the output current output power, can be used for common boost and buck module with over current protection, adjustable battery charger, LED driver, etc 5. Safety protection: LC filter, small output ripple, input anti-reverse connection protection, will not burn down, short-circuit protection, low-voltage protection. NOTE: 1. Pay attention to wiring according to the diagram and do not make mistakes. 2. The input IN of the module is prohibited from short circuiting with the output OUT, otherwise the constant current function will fail 3. Please ensure that the power of the power supply is always greater than the power required by the output load If the module wants to output at full load, the input voltage must be above 8V. When the input voltage is 5V, the output power is about 15W, and the voltmeter and ammeter will fail. The maximum current value of the module is 4A, subject to the maximum output power. For example, if the output is 17V, the current should not exceed 2A 4. The module is equipped with output short-circuit protection. After short-circuit protection, the module automatically shuts off the output and can be restored by powering on the module again. If your power supply does not have output current limiting protection, it is recommended to connect a fuse in series at the input front of the module to improve the safety factor.
