YX850 UPS Module 5-48V 10A Automatic Power Failure Switching Battery Backup Protector

The YX850 is an automatic power-failure switching UPS module designed to provide uninterrupted DC power to critical loads during mains failures or battery issues. Operating across a wide DC input range of 5V to 48V, this module automatically detects the loss of primary power and seamlessly transfers the load to a backup battery source, ensuring continuous operation of essential equipment. When mains power is restored, the module switches back to the primary supply and allows the battery to recharge, all without manual intervention.

This 10A power failure backup module is built for reliability in demanding environments, with an operating temperature range of -25°C to +85°C and a working humidity range of 5% to 95% RH. The automatic switching design eliminates the need for complex wiring or external controllers, making it an ideal drop-in solution for systems that cannot tolerate downtime. Whether used in SMS control systems, temperature and humidity controllers, elevator control panels, or other critical DC-powered equipment, the YX850 ensures that power interruptions do not translate into operational failures.

The module features a compact board size of approximately 61mm × 30mm × 18mm and a lightweight profile of around 24 grams, allowing for easy integration into existing enclosures and control cabinets. Its straightforward terminal layout simplifies connection to both the primary DC supply and the backup battery, reducing installation time and minimizing wiring errors. The YX850 is a practical and dependable choice for engineers and technicians seeking a robust automatic transfer solution for low-voltage DC backup systems.
