In recent years, with the development of society, computer room equipment system in the common application, in the process of production and learning depend on the degree of network is more and more high, once appear, network failure will seriously seriously affect our production and learning, so UPS
uninterruptible power supply is an important equipment to prevent and solve these faults.
UPS uninterruptible power supply has become a necessary equipment of computer room of UPS power supply has close relationship with the development of the computer, built a blackout of power supply system for any YongDianHu is very need.
But, not so perfect power system construction is the result of the computer system to promote.
Simply because it mains power grid power supply poor quality reach the requirement of the computer system for power supply, UPS power supply is a kind of technical measures to improve the quality of power supply.
Use UPS power supply can greatly improve the quality of power supply, UPS power supply is the purification of the power supply, to eliminate higher harmonic, improve the quality of the power supply, although general mains voltage waveform sine wave, but there are certain higher harmonic component.
The nature of the output voltage and frequency by load, large size, operation mode and load input and removal as well as the influence of the fault, and so on and so forth and interference, the output voltage and frequency is very unstable, so difficult to meet the requirements of computer for power supply quality.
Severe unstable power supply, can cause computer error or loss of information.
In UPS power supply control inverter using quartz crystal oscillator frequency constant, as well as automatic voltage regulating device, its small and 1 accuracy and higher harmonic on before 11 harmonics can filter out entirely, similar to sine wave output, thus purifying the power supply, ensure the normal operation of the computer.
Why UPS uninterruptible power supply is the indispensable equipment?
Is from the function: UPS can effectively purify the grid when the grid appear abnormal, can also in mains suddenly interrupted for a certain time to computer equipment such as power supply, can make you have ample time to deal with;
From the purpose: with the coming of information society, widely used in UPS from information collection, transmission, processing, storage to the application of each link, as is the importance of information increases with the increasing of application importance.
UPS uninterruptible power supply monitoring and control system by the front-end equipment, client/server APP, PC screen end three parts, the user can through the client APP/PC after landing the real-time check UPS equipment running status and the related parameters, but also in the mobile terminal screen intuitive care system operation condition and the related data, when an exception can be synchronous receive the alarm information.
In the extensive use of computer, the internal power supply system are equipped with high-speed under-voltage protection circuit.
When grid voltage computer by using filter capacitance of energy to maintain, in order to avoid the loss of data in memory, there must be a power supply to within less than lOms sending again, to ensure the normal operation of the computer system, timely deal with the information in the computer, and this power is called the UPS power supply.
Use can be greatly improve the reliability of power supply, UPS power supply backup power and keep phase lock is the power of the load power supply, and the pressure, and the frequency, and phase.
When the power switch power supply without interruption, also won't produce strong arc disturbance, the computer will not be lost information and data, to protect the computer equipment, especially the hard disk, not by power cuts and scratches.
With the rising popularity of computer application, information processing technology unceasing development, to put forward more and more strict requirements, the quality of power supply in the extensive use of computer, the internal power supply system are equipped with high-speed under-voltage protection circuit.
UPS uninterruptible power supply system is an important system in the computer room equipment, is to avoid computer room equipment losses due to the power grid vision.
