How to buy a computer room UPS?

Total number of batteries (power DC voltage * hours) per ampere-hour * number of blocks per group, where the power is the power of UPS, DC voltage is the voltage required for the power supply of UPS batteries, the UPS DC voltage of different power is different, the number of blocks per group is the minimum number of blocks required by the battery, when the battery is generally configured, it must be an integer multiple of the number of blocks per group, and the common UPS DC voltage and the number of blocks per group are as follows (each battery is calculated based on 12V):

For example, if a 5K8-hour delay UPS is configured, its power is 5000, the DC voltage is 96V, each group of batteries is 8, and 100Ah batteries are configured, and the total number of batteries required is: (5000 96*8) 100*8=32.

Each has its own benefits, and it is recommended that you buy a UPS

UPS (uninterruptable power supply) is a constant voltage and constant frequency power supply equipment containing energy storage devices with inverters as the main components, mainly used to provide uninterrupted power to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will supply the load after the mains voltage is stabilized, and the UPS at this time is an AC voltage regulator, and it also charges the battery in the machine; When the mains power is interrupted, UPS immediately uses the power of the battery in the machine to continue the alternating current to the load through the method of inverter conversion, so that the load can maintain normal operation and protect the load software and hardware from damage.

As a protective power supply device, UPS's performance parameters are of great significance and should be the focus of our purchase. Adapting to the wide range of mains voltage indicates that the utilization of mains power is strong (reducing battery discharge); If the output voltage and frequency change are small, it indicates that the adjustment ability of the mains is strong and the output is stable. The waveform distortion rate is used to measure the harmonic content of the output voltage; The voltage stability indicates the degree of stability of the output voltage when the UPS is suddenly added from no load to full load.

In addition, UPS efficiency, power factor, conversion time, etc. are all important parameters to characterize UPS performance, which determine the protection ability of the load and the utilization rate of the mains. The better the performance, the more protection. In general, offline (backup) UPS has poor load protection ability; **Interactive is slightly better; ** formula can solve almost all common power problems, and of course the cost also rises with the increase in performance.

Therefore, when purchasing UPS, users should choose different types of UPS according to the different requirements of the load for power and the different importance of the load.

UPS is not only directly used in computers, but also uses UPS instead of generators as backup power supplies for all equipment equipped with computers (such as medical CT, station instruments, etc.), radar stations, military communication systems, program-controlled systems, surgical operating rooms, etc.

What type of monitor is it? Whether it's an old-fashioned CRT display or an LCD or LED display, there is a lot of difference in power between the two. Not sure is not good to calculate.

Nowadays, it is generally LCD, so at least one 10kVA UPS is needed. The discharge time has nothing to do with the UPS power, only the battery capacity.

You can go to the UPS power supply ** to see Shante Emerson apc Meilan Rilan Sitong Shanton are all good, and you can also learn about the machine model parameters and so on alone is not comprehensive.

It depends on the configuration of your computer, but if your CPU is Intel, you can consider using 20kva, and if you are AMD, you need to use 30kva. The cost is not low, if you want to save money, you can use a backup machine with a PC, but this is not easy to manage.

I think if it's not a very important use, just a server with a UPS is fine.

A computer works about 300W

It is recommended to use 20kups

20pcs of 38ah batteries.

Algorithm: All your device power is added and divided by the power you need to provide and divided by the power you need to provide by the UPS capacity you need.

Basically, if you don't count the graphics card, a PC is less than 100W, and if you add a switch, you need at least a 1K-3K machine.

Specifically** Depending on which UPS you want to use, it is basically ABC, which is more expensive than the domestic one.

UPS is the English abbreviation of uninterruptible power supply, which is an important external equipment that can provide continuous, stable and uninterruptible power supply.

In principle, UPS is a kind of electric power and electric equipment that integrates digital and analog circuits, automatic control inverters and maintenance-free energy storage devices.

Functionally speaking, UPS can effectively purify the mains when there is an abnormality in the mains.

It can continue to supply power to computers and other devices for a certain period of time in the event of a sudden mains power outage, so that you can have enough time to cope.

In terms of use, with the advent of the information society, UPS is widely used in all aspects from information collection, transmission, processing, storage to application, and its importance is increasing with the increasing importance of information application.

When the grid voltage is normal, the mains voltage is used for the load after the UPS is stabilized, and the UPS itself is a good AC voltage regulator, which improves the power quality when disturbing, and it also charges the battery in the machine to store backup energy.

Based on the information you provide:

1.First of all, you need to know what the total power of the equipment in the computer room (including servers, routers, switches, etc.) is, if the total power of the equipment in the computer room is NKW, then it is more appropriate to configure the UPS with an apparent power of 2NKVA (it is reasonable for the UPS to have a load of 30%-70%)

2.Understand what is the DC working voltage of the selected UPS power supply (that is, how many batteries are in each group), if the number of batteries in each group is m, then the capacity of the battery configured according to the actual load is n*1000, which can meet the backup time of 5-6 hours.

3.Battery cabinets are available in different models and sizes according to the actual area of the installation site.

You can refer to the original imported UPS power supply of Yihuabao Electronics ELEN Yi'an.

What you said is the load of the entire computer room, choose UPS, you have to determine how big the load is first, choose a suitable head, and then look at the time required for redundancy The longer the time, the more batteries are powered, and it is estimated that there will be a lot of batteries for 12 hours of power supply, and then you have to consider the load-bearing capacity of each square of the computer room Because the battery is very heavy, a few words are nothing, if there are more, you have to consider this problem I know the most expensive brands that belong to APC, but the quality is definitely the best Their batteries are all battery packs are modular If the budget is enough, you can consider APC.

If you don't have a lot of budget, you can buy a better head, which is the main engine, and you can buy other brands of batteries.

Oh, our company is **IBM dell HP server, you can contact me if you need a server.

Mainly two, how much is the load power of UPS, at least to meet the total power consumption of the current equipment, leaving some space.

Buy a KSTAR YDE9102H 2KVA UPS! 16 x 100ah batteries! 1 A16 battery cabinet is OK!

Hello landlord! I am a professional in UPS power supply, and I am glad to answer for you. The power of your device is 750W+170W=920W.

Then you have to configure a minimum of 2000VA. If the delay only takes 5-10 minutes, then I recommend that you buy a 2000VA standard machine, as for the brand, I am not good to recommend to you. If you are satisfied, please adopt, if you still have questions, please continue to ask.

Copy your question and send me an email.

UPS means "uninterruptible power supply" in Chinese, which is the abbreviation of "uninterruptible powersystem uninterruptiblepowersupply" in English, which can ensure that the computer system continues to work for a period of time after a power outage so that users can save the disk urgently, so that users will not affect work or lose data due to power outages.

UPS is a system device that connects the battery (mostly lead-acid maintenance-free battery) to the main engine and converts direct current into mains power through the module circuit such as the main engine inverter. It is mainly used to provide stable and uninterrupted power to a single computer, computer network system or other power electronic equipment such as electric vertical pin magnetic valves, pressure transmitters, etc.

The main advantage of an uninterruptible power supply is its uninterruptible power supply capability. When the AC input of the mains power is normal, the UPS rectifies the AC power into direct current, and then converts the DC power into stable and impurity-free AC power for the use of the post-stage dry travel load.

Once the AC input of the mains is abnormal, such as undervoltage or power outage or frequency abnormality, then the UPS will enable the backup energy-battery, and the rectifier circuit of the UPS will be shut down, and accordingly, the DC power of the battery will be inverted into stable and impurity-free AC power, which will continue to be used for the rear load. This is where UPS's uninterruptible power supply capability comes in.

The computer should be no problem according to the doubling, the quality of UPS mainly depends on two aspects, on the one hand, the quality of the material, he affects the failure rate of the machine, and the failure time of a good brand is a little longer. On the other hand, the battery is the most expensive accessory in UPS, the cost of the battery is very large, what you need is just that the computer has time to shut down, generally speaking, the backup time is about 5 minutes.

A single UPS power supply system is the most basic uninterrupted power supply system, this kind of system is mainly composed of rectifier, inverter and battery three parts, if one of the three parts fails, then the power supply will be interrupted, so the power supply system without bypass circuit is less reliable and rarely adopted.

In order to increase the reliability of power supply, increase the bypass power supply, that is, the inverter and rectifier faults, connect the bypass power supply through the AC static transfer switch, and the power supply is supplied by the bypass power supply, and the conversion time of the static transfer switch is generally tens of milliseconds. Most of the small and medium-capacity UPSs use this wiring scheme.

The summary is as follows: the purchase of computer power supply should consider how much power the overall computer host needs, and then choose the power supply corresponding to the power. Power consumption varies depending on the configuration.

Choosing a power supply is not only to consider the power parameters of the power supply, but also to look at the evaluation of each benchmark value of the power supply on the evaluation**. ”
