2. Easy to read lcd display - the buck boost board is designed with a large clear digital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work. Constant current adjustable means that cc mode only works when the actual load output current is greater than the setting one, then it will become 2A for any load being connected.

Can flip or rotate voltage regulator display on this power supply unit, allows to set volts and limit the current, change the color of the background and parameters and switch the day/night display mode, power on off and accurate voltage setting return after power down.
The power supply step down converter support multiple functions.

0-55v; output voltage is 00-50v; output Current is 0000a-8. 100a; output power is 0-400W; can be arbitrary adjusted. Oah/oph/ohp function - when the recorded capacity/energy/operation time is higher than the setting maximum capacity/energy/time, the power supply will automatically turn off output, and "OAH"/"OPH"/"OHP" will flash on the screen.

Protection - with input low voltage protectionLVP, over voltage protectionOVP, over current protectionOCP.

Safe protection: the module is with anti-reverse connection protection of input end, and the protection threshold is adjustable. No need to add anti-backflow diode when charging. Application: the volt conversion board can be used as an ordinary buck/Boost module with over-current protection; used as a high-power LED constant current driver module; DIY a solar power controller, Battery Charging.

The module can be set to ON/OFF by default. Good thermal performancee:output ripple is small and πfilter is available. Thick heat sink. Buck-boost Integrated. Safe protection: the module is with anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection.
Data reference:input voltage range is dc 5-30v; output voltage range is dc 05-30v, can be arbitrary adjustable; output current can be 3A for long term use, if enhance dissipation, it can reach 4A; max output power is 35W, if enhance heat dissipation, it can reach 50W. No need to add anti-backflow diode when charging. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off.

Note - leave a margin for the power supply to ensure it can long-term stably working.
Protection - this voltage stabilizer comes with over-current protection, underground, can be used in various situations such as car, over-temperature protection; adopts potting technology, dust-proof, moisture-proof and shock-proof, characterized by waterproof, outdoor, etc.
