Frequently Asked Questions
Q: What input voltage range does this power supply module support?
A: This adjustable voltage regulator module accepts an input of DC 6V to 25V (greater than 1A), making it compatible with a wide range of standard power sources commonly used in electronics labs and competition setups.
Q: What output voltages can I get from this module?
A: The module provides three output options: a fixed DC 3.3V, a fixed DC 5V, and a fully adjustable output ranging from DC 1.25V up to the input voltage (Vin), giving you maximum flexibility for powering different components.
Q: Is this module safe to use with my smart car or robotics project?
A: Yes. The module is specifically designed for smart car competitions, robotics, and electronic contests. It includes four self-restoring fuses and three LED power indicators that alert you immediately if a short-circuit condition occurs, helping to protect your components and your board.
Q: What does it mean if one of the power indicator LEDs turns off?
A: If any of the three power indicator LEDs goes off during operation, it indicates a short-circuit condition on the load. You should immediately disconnect the power supply to prevent any damage to the module or connected devices. The self-restoring fuses will reset automatically once the fault is cleared.
