About This

Functions & Features】The 100A 2P dual power automatic transfer switch is designed for infrequent PC-level switching, supporting both automatic and manual operation. It can test the status of the main power and backup power in real time. When Source A fails, the system switches to Source B within 0.05s to ensure continuous, reliable, and safe power supply. Once Source A restores, it automatically switches back. Both power inputs support mains, generator, or photovoltaic connections.
【Automatic Mode】In Auto Mode, set the left switch to “Auto” and the right handle to Source A. When Source A is normal, the A indicator (red light) stays on. If Source A fails, the A light turns off and the system automatically switches to Source B within 0.05s, with B indicator (green light) turning on. Once Source A recovers, it will automatically revert from backup to the main source.
【Manual Mode】In Manual Mode, set the left switch to “Manual.” Choose Source A or Source B by turning the right red handle. The corresponding LED indicator will display the selected source: Source A (red light) or Source B (green light). This mode allows flexible control for inspection, testing, or special operating needs.
【Voltage Protection & Safety】 This 110V ATS transfer switch is compatible with 50/60Hz dual power grids and designed for PZ30 rail mounting. Built-in protection values: undervoltage 85V, recovery 95V; overvoltage 145V, recovery 130V (±5V). The switch is made with flame-retardant PA6 material and silver contacts, ensuring over-voltage, under-voltage, overload, and short-circuit protection for maximum reliability.
【Wide Application & Warranty】 Suitable for areas where uninterrupted power is critical, including homes, farms, laboratories, hospitals, cold storage, data centers, and emergency systems. Compact 2P ATS design supports indoor and outdoor generators. Backed with 30-day free returns and 3-year warranty, ensuring a worry-free shopping and long-term use.
