12 V automatic power controller for uninterrupted DC power What this product does Monitors input power and automatically switches to a backup battery to prevent interruptions. Supports continuous battery charging while the main power source is present. Designed for fast emergency switching to maintain power during outages. Key benefits Reliable uptime: Automatic switching keeps connected equipment running without manual intervention. Sufficient capacity for many DC applications: Handles up to 12 A and up to 150 W at 12 V, suitable for devices that require stable 12 V power. Fast response during power loss: Emergency switching minimizes downtime and prevents service interruption. Simplified power management: Integrates automatic backup and charging functions so you do not need separate controllers. Performance and compatibility Electrical capacity: Up to 12 A current, maximum 150 W at 12 V. Function: Automatic transfer to backup battery, continuous charging when mains power is available, quick transfer during outages. Compatible with common 12 V battery systems and 12 V DC equipment rated within the specified current and power limits. Practical applications Incubation cabinets: Maintain stable power to temperature control systems during brief outages to protect samples and experiments. Small servers and desktop systems: Keep critical computing and storage equipment running long enough for graceful shutdown or to bridge brief interruptions. Network equipment: Provide uninterrupted power to routers, switches, and modems to preserve connectivity during mains disturbances. Why choose this device Straightforward protection for 12 V DC setups that need reliable, automatic backup switching. Clear electrical limits let you match the controller to your battery and load requirements. Combines automatic transfer and charging functions in one unit to reduce wiring and complexity. Installation and use notes Verify that the total device load does not exceed 12 A or 150 W at 12 V. Use with an appropriate 12 V battery and wiring sized for the maximum current. Intended for integration into DC systems where automatic battery backup and charging are required.
