Application of UI in vehicles

The damage caused by external power failure is very important. UI power and generator maintenance and disaster planning should be part of the data center's routine operations. With the continuous increase of various large-scale power equipment, many equipment will use higher power UI uninterruptible power supply. At present, the maximum power UI UI UI can achieve 800kVA, and can also realize multiple parallel operation. The backup time of conventional high-power UI power supply is 15-30 minutes, and users can also provide longer time according to their own needs, but this needs to match with the generator set in order to provide more continuous power supply.
Sudden power outages can paralyze data center operations. Power outages are harmful to it systems because they can lead to data loss, file corruption, and device damage. An on-site data center requires a backup power system directly integrated into the power infrastructure to ensure that critical systems remain online.
Data center power infrastructure should support two operation modes: normal operation and emergency operation. In normal operation mode, the data center is connected to the power lines of one or more utility companies, and some enterprises may use diesel generators to meet their power demand. The diesel generator set is suitable for the occasions that the municipal power grid can not be transmitted to the communication bureau station, mining area, forest area, pastoral area and national defense project. It is required to be able to provide independent power supply as the main power supply for power and lighting. For the area of city power supply, and the power supply reliability is high, the units that do not allow power failure and require to restore power supply quickly within seconds, such as communication, banks, hotels, airports and other important departments, can be used as emergency backup power supply, once the city power failure, it can quickly provide stable AC power supply.
 
The importance of UI
Data centers usually deploy one or more automatic transfer switches to switch between utility and standby power. In case of power interruption or failure, the transfer switch sends a start command to the connected standby diesel generator, and then provides power when generating power. Once the utility power is restored, the transfer switch switches to the mains power supply and sends the shutdown command to the diesel generator. 　　
The power infrastructure of the data center includes one or more UI power supplies. UI has two key uses: to protect it equipment from spikes and to provide short-term power in the event of a power failure. When the mains power input is normal, UI will supply the power supply to the load after voltage stabilization. At this time, the UI is an AC mains voltage regulator, and it also charges the battery in the machine. When the mains power is interrupted (emergency power failure), the UI will supply the load The power of the battery inside the machine is immediately supplied to the load with 220 V AC by means of inverter conversion, so as to maintain the normal operation of the load and protect the software and hardware of the load from damage. UI equipment usually provides protection for over voltage and low voltage. 　
Another common power infrastructure component is the power distribution unit (PDU), an advanced power outlet that takes power from UI power and distributes it to it systems. Distribution units (PDUs) do not generate power spikes, which is why distribution units (PDUs) are usually used with UI power supplies. PDU is also known as the power distribution socket for cabinet. PDU is a product designed to provide power distribution for cabinet mounted electrical equipment. It has a variety of series specifications with different functions, installation methods and different plug-in combinations, which can provide suitable rack type power distribution solutions for different power supply environments. The application of PDU can make the power distribution in the cabinet more orderly, reliable, safe, professional and beautiful, and make the maintenance of power supply in the cabinet more convenient and reliable.
Through the use of industrial standard PDU products, the power supply security of network products can be improved to meet the requirements of power input of important equipment. The ground wire detection circuit can effectively and truly detect whether your power supply line is grounded and the quality of grounding wire through the indication of high brightness LED, and remind you to connect and maintain good grounding wire, so as to ensure smooth lightning protection and discharge channel and power safety. With the development of computer network technology, the demand of servers, switches, various electronic equipment and other key equipment is also increasing, the business undertaken by them is becoming more and more critical, and the requirements for the environment where the equipment is located (such as machine room, cabinet, etc.) are also higher. All facilities participating in the operation of key equipment must have high reliability and availability. For the power socket, it is the last pass for all equipment to use electricity. If it is not stable enough and lacks sufficient protection function, it may lead to the destruction of expensive equipment and even the collapse of the whole system. 　　
Its power regulation and routing are completed through switch cabinet or main distribution board and transformer. This ensures that the supply voltage and current output is normal. The equipment configuration depends on the size of the data center, the number and type of IT systems.
 
How to ensure continuous operation
 
The data center power infrastructure must provide power for other equipment in the data center facility, such as lighting, alarms, sensors, fire monitors, cooling devices, and dehumidifiers. Its power infrastructure must also provide power to it systems, such as servers, storage devices, and network components, so that they can operate uninterrupted even if power is lost.
During normal operation, the power supply targeting it system will continuously run through UI power supply. The UI power supply ensures that the connected battery is fully charged and is ready to support emergency operation. Depending on the number and type of batteries, batteries can provide enough power to enable it systems to operate in a short period of time.
UI can be divided into three types: offline, online interactive and online. If the mains power is interrupted, the UI power supply will switch to the power supply state, convert it to AC and send it to the PDU. on-line
