About This

Automatic Switching: In case of undervoltage, overvoltage, or overcurrent, the system automatically switches to backup power; Once the fault is cleared, it switches back to the primary power source (L1/L2 can be flexibly set); This ensures stable power, intelligent load distribution, and uninterrupted operation of critical facilities
Safety & Quality: Made from high-quality PA6 material, it offers excellent insulation, durability, and resistance to high temperatures and corrosion; It prevents electrical faults and short circuits, ensuring stable long-term operation; With a V-0 flame retardant rating, it complies with safety standards, effectively preventing fire hazards for safe use
LED Real-Time Display: The LED screen clearly shows the device's operating voltage and current, allowing easy monitoring and early detection of potential failures to prevent circuit damage; LED indicators also display the operating status, including over-voltage, under-voltage, and main/backup circuit operation, ensuring a safer, more reliable user experience
Adjustable Settings: Users can easily adjust parameters such as overcurrent value, priority phase (L1/L2), startup delay, and transfer delay via buttons; After making adjustments, simply press and hold the "SET" button to save the settings; This allows the device to meet various load and application requirements
Easy Installation: With a compact size and standard installation interfaces, it can be easily installed even by non-professional users; The included manual provides clear wiring instructions, and the unit comes with an installation rail approximately 3.54 inches (9 cm) long; The rail installation is simple, saving time and effort
