2. Examples of application scenarios
Large cloud computing center: equipped with several hundred kVA to MW level power frequency UPS (such as multiple 800kVA UPS connected in parallel), combined with diesel generators to form a "dual active" power supply architecture, ensuring uninterrupted operation of cloud services such as Baidu and Alibaba 24/7.
Edge computer room: deploy small and medium-sized power frequency UPS (50-200kVA) at 5G base station and Internet of Things gateway to resist power grid fluctuations in remote areas.
2、 Industrial Manufacturing and Automation Scenarios
1. Core requirements
Prevent production interruption, product scrap, or equipment damage caused by power outages or voltage drops in automated production lines and precision machining equipment (such as CNC machines).
Support the surge current when starting inductive loads such as motors and frequency converters (starting current can reach 3-5 times the rated current), to avoid UPS overload protection shutdown.
2. Examples of application scenarios
Automotive manufacturing workshop: provides power supply for the PLC control system of welding robots and spraying assembly lines. For example, Tesla Gigafactory uses multiple 200kVA power frequency UPS in parallel to ensure the continuous operation of body stamping equipment.
Semiconductor wafer fab: supplies power to the deposition/etching equipment in the cleanroom, requiring UPS harmonic distortion THD<2% to avoid power grid interference affecting chip yield.
Petrochemical industry: Install power frequency UPS in the DCS (distributed control system) of refining equipment and natural gas pipelines to prevent power outages from causing safety accidents.
3、 Medical and life science fields
1. Core requirements
Provide "zero interruption" power supply for emergency equipment and life support systems to ensure patient safety in scenarios such as surgery and intensive care.
Meet the strict requirements for power stability of medical equipment (such as CT, MRI) (voltage fluctuation ≤± 1%, frequency fluctuation ≤± 0.1Hz).
2. Examples of application scenarios
Operating room and ICU: Equipped with 10-50kVA power frequency UPS to supply power to anesthesia machines and electrocardiogram monitors. For example, the cardiac surgery operating room in tertiary hospitals usually adopts a "2N" redundant configuration (two sets of UPS independently powered).
Medical Imaging Center: Provides power to 3.0T MRI equipment, which can reach a power of 100kW when started. The power frequency transformer of the power frequency UPS can effectively suppress voltage drops during startup.
4、 Finance and Securities Industry
1. Core requirements
Ensure the real-time trading continuity of bank data centers and securities trading systems, and avoid the loss of trading data or financial disorder caused by power outages.
Support low latency power supply requirements for high-frequency trading servers, ensuring millisecond level trading responses are not affected by power fluctuations.
2. Examples of application scenarios
Bank Head Office Data Center: Deploy 1000kVA or above power frequency UPS, paired with dual bus power supply architecture (2N system). For example, Industrial and Commercial Bank of China's data center uses Eaton 93PM series UPS to ensure the operation of account settlement systems nationwide.
Stock Exchange Data Room: Provides power to the market server and trading matching engine, requiring UPS switching time to be less than 1ms to avoid abnormal stock price fluctuations caused by power outages.
5、 Energy and Infrastructure Sector
1. Core requirements
Ensure the power supply of control systems for key infrastructure such as electricity, transportation, and communication, and guarantee uninterrupted social and public services.
In extreme weather conditions (such as typhoons, earthquakes) or power grid failures, provide long battery life (such as more than 8 hours) to buy time for emergency repairs.
2. Examples of application scenarios
Power system: Deploy power frequency UPS in the relay protection devices and dispatch automation systems of substations and nuclear power plants. For example, the 500kV substation of State Grid uses Delta N-400K series UPS to prevent power grid dispatch interruptions.
Transportation hub: provides power supply for airport tower communication equipment and railway signal systems, such as multiple 500kVA power frequency UPS systems installed at Beijing Daxing International Airport to ensure stable operation of flight takeoff and landing command systems.
Communication base station: Deploy long latency models (with external battery cabinets supporting 4-hour battery life) in remote or mountainous areas to ensure 4G/5G signal coverage is not affected by interruptions.
6、 Research and high-end manufacturing fields
1. Core requirements
Provide ultra stable power supply for precision scientific research equipment such as particle accelerators and synchrotron radiation sources to avoid power fluctuations affecting experimental data accuracy.
Support the power supply requirements of nanoscale processing equipment (such as lithography machines) and suppress the interference of power grid harmonics on equipment accuracy (THD needs to be<1%).
2. Examples of application scenarios
National laboratory: power supply for strong magnetic field scientific devices, such as the stable strong magnetic field device of the Chinese Academy of Sciences Hefei Institute of Physical Sciences, which uses customized MW power frequency UPS to ensure that the magnetic field strength is stable above 100 Tesla.
Semiconductor lithography machine: ASML's EUV lithography machine requires extremely high power stability and needs to be combined with a power frequency UPS+voltage regulator to prevent damage to the scanning accuracy of the photomask due to power fluctuations.
7、 Military and Aerospace Fields
1. Core requirements
In scenarios such as field operations and space launches, resist complex power grid environments such as electromagnetic interference and voltage transients, and ensure reliable operation of equipment such as radar and missile control systems.
Meet the high reliability standards of military equipment (such as MTBF ≥ 100000 hours) and support stable operation in a wide temperature environment (-20 ℃~50 ℃).
2. Examples of application scenarios
Radar station and command center: Deploy military grade power frequency UPS with anti surge and anti electromagnetic pulse (EMP) capabilities. For example, the border radar station uses reinforced power frequency UPS to ensure uninterrupted air situation monitoring.
Space Launch Site: Provides power for rocket launch control systems, such as the UPS at Wenchang Space Launch Site, which must meet space level reliability requirements and support zero error power supply during the launch countdown phase.
Selection and deployment suggestions
Match capacity based on load characteristics: For inductive loads (such as motors), UPS capacity should be configured at 2-3 times the rated power to avoid overload during startup.
Redundancy design priority: Financial, medical and other scenarios prioritize the use of 2N dual bus architecture, data centers recommend N+1 redundancy, and industrial scenarios can choose single machine or parallel configuration according to risk level.
Environmental adaptability optimization: Models with heat dissipation modules should be selected for outdoor or high-temperature environments, moisture-proof heating devices should be installed in humid areas, and air filtration systems should be installed in dusty environments.
High power frequency UPS, through the deep coupling of technical characteristics and scenario requirements, has become the core equipment for power guarantee in key fields. The expansion of its application scenarios also promotes the development of products towards higher efficiency and intelligence (such as integrated intelligent monitoring systems and energy management platforms).
