Realtime voltage display: shows output voltage instantly with 0.1V accuracy, eliminating the need for separate detection and enabling quick adjustments to lighting brightness or motor speed. Maximum current capacity: supports up to 8A instantaneous load with a recommended longterm operation of 5A; provides 7V, 12V, and 24V outputs within a 536V input range for a variety of DC load applications. Robust component design: built with the XL4016 switchtype regulator chip and the MBR10200 dual rectifier, plus circuit protection to prevent overload damage and extend the module lifespan. Versatile usage: suitable for electronic maintenance, rectifier bridge integration, and DC power supply projects; allows precise of voltage output to match different operational needs. Use scenario: electronics maintenance and systems that require adjustable, monitorable DC power to test or fixed supplies without external measurement tools. Use scenario: DIY lab bench or prototyping setup for testing circuits and components with selectable 7V, 12V, or 24V outputs from a 536V input source. Use scenario: small motor or LED projects where immediate voltage feedback and reliable protection help optimize performance and prevent damage.
