According to relevant design regulations in my country, Class I and Class II loads should be powered by dual power supplies. When Class I loads lose power, it may cause equipment and personal accidents, and when Class II loads lose power, it will cause equipment accidents. The dual power supplies of Class I loads should be set up for automatic mutual switching. When one side of the power supply disappears, the backup power supply will be immediately switched and the working power supply will be disconnected; the dual power supplies of Class II loads can be manually switched or manually switched by remote control.
