Frequently Asked Questions
Q: What input voltage range does this DC-DC boost module support?
A: The module supports two selectable input voltage ranges via a PCB jumper on the back: 8–16V (suited for 3-cell lithium battery packs and standard 12V systems) or 10–32V (wide-range input for versatile applications). The module ships with the 10–32V range set by default.
Q: Can I use this module to charge large capacitors?
A: Yes — this module is specifically designed for capacitor charging applications. It can charge a 470µF capacitor to 390V in approximately 2 seconds, and a 4,700µF capacitor to 390V in around 18 seconds. Its regulated output voltage remains stable throughout the charging cycle.
Q: What built-in protections does this boost converter have?
A: The module includes short-circuit protection (10A input fuse), over-current protection (output voltage reduces when input current exceeds 4.5A), over-voltage protection (activates above 410V output), and reverse-polarity protection (non-self-recovering fuse). Note: Do not short-circuit the output directly as this may damage the rectifier. Always use a current-limiting resistor if arc testing is required.
Q: Is the output voltage adjustable and stable?
A: Yes. The output voltage is continuously adjustable from 45V to 390V using the onboard potentiometer. Once set, the regulated output remains stable regardless of fluctuations in the input voltage, making it suitable for precision high-voltage applications.
