Mini ATS Automatic/Manual Transfer Switch 2P 63A 220V AC Dual Power Changeover Switch for Home, Solar Generator, RV and Backup Power Supply, DIN Rail Mount, 50/60Hz

• 0.05-Second Rapid Automatic Switching: This ATS (Automatic Transfer Switch) monitors the status of the main and backup power sources in real time; when abnormal conditions such as a power outage, undervoltage, or overvoltage occur in the main power source, it automatically switches to the backup power source in approximately 0.05 seconds; It automatically switches back to the main power source once normal operation is restored, helping to maintain power supply continuity, reliability, and safety,the transfer switch housing is made of high-strength, flame-retardant PC material, which offers excellent insulation performance and features high-temperature resistance and anti-aging properties
• Automatic/Manual Dual Mode: This ATS transfer switch supports both automatic and manual operating modes. In automatic mode, it monitors the power supply status in real time to perform automatic power switching; in manual mode, the handle allows for flexible selection of power circuits, making it suitable for emergency power supply scenarios as well as for equipment debugging and testing
• 220V Overvoltage and Undervoltage Protection: This automatic transfer switch is designed for AC 220V, 50/60 Hz dual-power systems and supports operating currents from 6 A to 63 A; 220V/50Hz undervoltage threshold: 175V; recovery threshold: 195V; overvoltage threshold: 260V; recovery threshold: 240V (±5V); the unit promptly switches power sources when abnormal voltages occur, providing a more stable power supply environment for electrical equipment
• Standard DIN Rail Mounting: Features an ultra-slim, compact DIN rail mounting design that saves space inside the distribution panel and facilitates electrical wiring layout; M5 terminal screws accommodate 1–25 mm² wires, ensuring a secure and stable connection, suitable for applications such as residential power distribution systems, generator backup power systems, and dual-power systems combining utility power and inverters
• Wide Range of Applications: This dual-power-source automatic transfer switch is suitable for homes, factories, laboratories, data centers, cold storage facilities, emergency power systems, and other locations requiring a stable and continuous power supply, it can be used with utility power, inverters, or generator backup power sources, and quickly switches to the backup power source in the event of a main power failure, minimizing the impact of unexpected power outages on equipment operation

Rail/Screw Installation

Features a quick-mount design for DIN rails, allowing for easy installation on standard 35-millimeter DIN rails

Manufactured with a high-quality, flame-retardant PC housing, it offers high heat resistance, long-term stability, and durability

Compact transfer switches (total weight ≤ 0.5 kilograms) are small and lightweight, making them easy to install and maintain

The ATS transfer switch automatically switches power sources; its handle enables manual circuit selection for emergencies and debugging
