Dual Power Automatic transfer switch in which areas are more widely used?

Dual Power Automatic Transfer switch is widely used in the following fields:
Medical Field: key departments such as operating room, intensive-care unit room (ICU) and emergency room, as well as various medical equipment such as CT scanners, magnetic resonance imagin (MRI) equipment, artificial pacemaker, etc. , both require a dual power supply. To ensure that when one power failure, the other can be put into use immediately, to prevent power outages caused by medical equipment stop working, endangering the lives of patients.
Industrial Field: in the production process of chemical, steel, electronics and other industries, many key equipment can not be interrupted at will. For example, the mixing motor of the reactor in the chemical industry, the blast furnace control system in the steel plant, and the semiconductor manufacturing equipment in the electronics plant, the dual power supply provides reliable power for these devices, avoid serious consequences such as production interruption, product scrap and even equipment damage caused by power outages.
Transport sector: Airport Air Traffic Control System, runway lighting system, as well as the railway signaling system, railway electrification system power supply system, etc. , rely on dual power supply to ensure operation. If there is a power failure at the airport, the air traffic control system will not work properly, which will cause flights to be unable to take off and land. If there is a power failure in the railway signaling system, it may cause a train operation accident, dual power supply can ensure that these critical systems in any case can be normal power supply, to ensure the safety and smooth transportation.
Communication Field: Communication Base Station, switching center and other communication facilities need continuous and stable power supply to ensure the normal operation of the communication network. If the power failure of communication facilities, will lead to a large area of communication interruption, affect people's daily life and work. The dual power supply can effectively prevent communication interruption caused by power failure and ensure the continuity of information transmission.
Financial Field: the core departments of financial institutions, such as the data center of banks and the trading system of stock exchanges, have high requirements for the reliability of power supply. Power outages may lead to transaction data loss, business interruption, and bring huge economic losses to financial institutions and customers. Dual power supply for these critical systems to provide stable power to ensure the security and stability of financial transactions.
Data Center area: Data Centers store a lot of important data, and servers and other equipment need to run 24 hours a day. The dual power supply system can quickly switch when a power supply has a problem, ensure the normal operation of data center equipment, and avoid data loss and service interruption.
Business Field: large shopping malls, supermarkets, hotels and other commercial places, in order to ensure the normal operation of key equipment such as lighting, air conditioning system, elevator operation and cash register system during the business period, dual power supply will also be used. Especially in crowded business hours, sudden power outages may cause panic and safety accidents. Dual power supply can effectively reduce the risk of power outages and provide a comfortable and safe shopping and accommodation environment.
