About This

Intelligent Automatic Switching: It is compatible with 110V and 220V. This automatic transfer switch detects undervoltage, overvoltage, or overcurrent in the primary power source (L1) and automatically switches to backup power (L2). It reverts to L1 once faults are cleared, with flexible L1/L2 priority settings to suit your needs.
Adjustable Parameters for Customization: Users can easily modify overcurrent value, startup delay, transfer delay, and priority phase (L1/L2) via buttons. Simply hold the "SET" button to save settings, ensuring compatibility with diverse loads and applications.
Safety-Enhanced Construction: Made from high-quality PA6 material with V-0 flame retardant rating, it offers superior insulation, high-temperature resistance, and corrosion protection. Prevents electrical faults and short circuits for safe, long-term operation.
LED Real-Time Monitoring: The built-in LED screen displays operating voltage and current, while indicators show status (overvoltage, undervoltage, main/backup circuit activity). Enables easy fault detection and ensures reliable performance.
Versatile & Easy Installation: Compact design with standard interfaces and included installation rail allows hassle-free setup—even for non-professionals. Ideal for commercial/industrial facilities, hospitals, data centers, and telecommunications hubs needing stable power.
