Suitable for scenarios that cannot tolerate power outages, such as hospitals, low-temperature cold storage, data centers, and other high-demand situations. When the main power supply fails, it can automatically and quickly switch to the backup power supply to ensure the safety and reliability of the electricity supply.
Both are equipped with indicator lights. In automatic mode, when the normal power supply A is working properly, A (red light) is on; when the normal power supply A is abnormal, A (green light) goes off. In manual mode, if power supply A is selected, operating the red handle on the right towards power supply A will turn on the red light for A. If power supply B is selected, manually operating the red handle on the right to switch towards power supply B will turn on the red light for B.
