Product Details
✓【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】Set the selector to Auto and the red handle to Source A. If Source A fails, it transfers to Source B and switches back after recovery. Rated transfer time is 0.05 seconds; this ATS is not a UPS, so a brief interruption may occur.
✓【Manual Mode】Set the selector to Manual, then use the red handle to select Source A or Source B. The corresponding red A or green B indicator identifies the selected input for inspection, maintenance or system testing.
✓【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 RV, 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.
