Suitable for indoor and outdoor generators
- Manual Mode: guetneu automatic transfer switch use manual mode to make sure the left switch is in Manual. If you choose power source A, operate the red switch handle on the right to point to Sonrce A, and LED indicator A (red light) will be on. If you choose power source B, manually operate the red switch handle on the right to point the switch to Source B, and LED indicator B (red light) will be on.
- Functions and Features: 100a 2p dual power auto transfer switch W2R is a PC-level infrequent switching switch, mainly used for automatic or manual conversion of two power supplies, and can test whether the common power supply or backup power supply is normal. When the common power supply A is abnormal, the backup power supply B is quickly switched and put into use within 0.05 seconds to ensure the continuity, reliability and safety of power supply. When the common power supply returns to normal, it automatically switches from the backup power supply to the common power supply. Both power supply A and power supply B can be connected to the mains/generator/photovoltaic, with four wiring.
- Automatic Mode: ac 110v automatic transfer switch use the automatic mode, the left switch must be in the Auto, and the red handle on the right should point to Source A. When the normal power source A is working normally, A (red light) is always on; when the normal power source A is abnormal, A (green light) goes out and switches to the automatic power source B within 0.05 seconds, and B (green light) is on. When the normal power source A returns to normal, it will automatically switch from the backup power source B to the normal power source A.
- 110V Over-Voltage and Under-Voltage Protection: automatic transfer switch 110v designed for home track installation, dedicated to PZ30 distribution box. This series of automatic transfer switches is suitable for 50/60Hz dual power grid. The working current is 100A. 110V/50Hz Undervoltage value: 85V, Recovery value: 95V; Overvoltage value: 145V, Recovery value: 130V (± 5V). Please select the 2p 100a transfer switch dual power automatic changeover switch 110v with the corresponding specifications according to the actual working voltage you need
