Feature: 1. MILLISECOND SWITCHING: When there is an abnormality in the normal power supply, the automatic transfer switch will switch in millisecond to the backup power supply to ensure the continuity of the power supply. 2. AUTO MANUAL MODE: This dual power transfer switch can be operated automatically or manually, which is isolated anti interference, reliable and stable. 3. STANDARD RAIL INSTALLATION: The power transfer switch adopts standard 35mm rail installation method, specially designed for PZ30 distribution box. 4. EXCELLENT MATERIAL: The changeover switch adopts flame retardant PC shell, with good insulation and heat resistance. Silver contact is anti aging, with excellent conductivity. 5. WIDELY USED: The power transfer switch can be used in various occasion where continuous power outages are not allowed, such as home, shopping mall, factory.

The maximum ambient temperature shall not exceed 40℃, the minimum temperature shall not be less than ‑5℃, and the average temperature within 24 hours shall not exceed 35℃. 2. The altitude of the installation site should not exceed 2000m. 3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%. When the temperature is at the lowest temperature of ‑5℃ and the relative humidity is high, for example, at a temperature of 25℃, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation on the surface of the product. How To Use 1. Before installation, please check the integrity of the ATS, use the operating handle to turn it on or off, check the flexibility of the transmission device, and detect the generation and disconnection conditions of normal and backup power loads at each stage. 2. Wiring and use according to wiring diagram.
