Antwire XL4015 Adjustable Step Down Board Alternative Energy Electronic Hobby Kit

XL4015 DC-DC Adjustable Step-Down Converter Module with LED Voltmeter, 75W 5A This high-performance XL4015 buck (step-down) DC/DC converter is ideal for DIY power supplies, battery charging, LED drivers, and general voltage regulation. It converts 4.0–38V DC input to an adjustable 1.25–36V DC output with up to 5A output current and 75W maximum power, offering high efficiency (up to 96%), low ripple, and excellent line and load regulation. An onboard digital voltmeter with LED indicators lets you easily monitor either input or output voltage at the press of a button. Another button allows you to switch the display off if not required, and both the display state and measurement mode are stored in memory, even after power-off. The built-in calibration function ensures accurate voltage readings (4–40V range, ±0.1V). Protection features include thermal shutdown, current limiting, and output short-circuit protection for safer, more reliable operation. Note: there is no reverse polarity protection; if needed, use a suitable high-current diode in series with the input.
