About This

Automatic and manual switching: Using advanced microcontroller technology, the system will automatically switch to the backup power supply (L1/L2 can be flexibly set) in case of undervoltage, overvoltage, or overcurrent; Switch back when the main power is restored.
Adjustable settings: Adjust parameters such as overcurrent value, overvoltage value, priority phase (L1/L2), startup delay, and transmission delay through buttons; After adjustment, simply press and hold the "SET" button to save the settings; This enables the device to meet various load and application requirements.
Real time monitoring of LED display screen: equipped with high-definition LED display screen and status indicator, real-time voltage and current monitoring and operation status updates. Ensure stable operation of the circuit.
Safety and Quality: Made of high-quality PA6 material, it has insulation, durability, high temperature resistance, and corrosion resistance; Prevent electrical faults and short circuits to ensure long-term stable operation; V-0 flame retardant rating, in compliance with safety standards, effectively preventing fire hazards and ensuring safe use.
Widely applicable: Suitable for environments that require stable and reliable power supply, including commercial and industrial facilities, hospitals, residential areas, telecommunications hubs, and other scenarios.
