How many hours does the UPS last at most? In what power? ）

24 hours to give you a value...

The power supply time depends not only on the battery capacity, but also on how much load you have to calculate the time.

You have to ask this question for the longest, there is no such definition.

Nowadays, many UPS are equipped with multiple battery packs, and the more battery packs, the longer the time.

I only have one sentence, which is: it can only be represented by n.

What I want to say is that "the working time of UPS when the mains power is interrupted depends on the battery capacity you install and your load power, but the battery capacity you are equipped with cannot be infinite, it must be below the rated capacity of your UPS, otherwise after the mains power is restored, the current charged for the battery is too large, and exceeding the UPS capacity will cause the UPS protection to jump" I don't agree with this point of view, I want to ask my friends Isn't the UPS you make adjust the charging current according to the battery capacity, and your charging pad has no current limit? We produce the charging current that can be adjusted according to the battery.

It is best not to connect battery packs in parallel without the manufacturer's permission. This practice is dangerous.

The working time of UPS when the mains power is interrupted depends on the battery capacity you install and your load power, but the battery capacity you are equipped with cannot be infinite, it must be below your UPS rated capacity, otherwise after the mains power is restored, the current to charge the battery is too large, and exceeding the UPS capacity will cause UPS protection to jump.

It depends on how big the storage battery you use, generally how many ampere-hours are used for the capacity, the larger the capacity, the longer it will be used.

Summary. Hello, I'm glad to answer your questions. The power supply time of the home computer UPS can generally last for 20 minutes.

The large kilowatt UPS power supply can be set up with a battery pack according to the requirements, generally more than 1 hour to 10 hours. Ordinary household UPS power supply for ten minutes to half an hour, it is recommended to use 500V can be used for another 10-15 minutes after power failure. The continuous working UPS power supply has high requirements for heat dissipation, and the UPS for seven or eight hours or even higher is for the server.

Taiqifeng UPS power supply.

The length of UPS uninterruptible power supply after a power outage is determined by its backup battery. Generally, the standard UPS battery is equipped with one hour of power supply at full load according to the output power of UPS. You only need to use a computer, a home computer power is up to 300W, UPS power supply with 500W (considering the large startup current) can meet the power supply conditions for two hours, need to power for a long time, increase the backup battery.

According to the battery capacity provided, double the battery power supply time for two hours.

Hello, I am helping you to inquire about the relevant information, and I will reply to you within five minutes, please wait for a while Hello, I am very happy to answer for you.

1. To determine how much power your device has, generally speaking, the power of ordinary PC or industrial computer is about 200W, Mac is about 300W, and the server is between 300W and 600W.

2. Determine the model of the host to calculate the required capacity of the battery, the battery is to determine the length of the backup battery life.

3. Sometimes with a set of Chongbi pure UPS power supply, generally speaking, it is best to ask professionals to take a look at it now, because it is best to understand the situation on the spot.

The main function of the UPS power supply is to be emergency and prevent the loss of important data due to sudden power failure.

As for how many hours the UPS power supply can be used, it is generally related to the load power after the mains power is stopped. In the case of a super-ups power supply, a standard battery can only be used for emergency shutdown for about 5 to 10 minutes after a power outage. If you need a long delay, you can equip it according to your needs, such as 2 hours, 4 hours, etc.

The extended time is determined to refer to the time when the battery is powered at full load, such as 2 hours at full load and 4 hours at half load, and finally equipped according to demand.

The delay time is best within 8 hours after the power outage for the following reasons:

Some users only pursue the backup power supply time when choosing UPS power supply, requiring 4 hours, 8 hours or even more than ten hours, but ignore the reliability and economy of the entire power supply system.

This is because: a) Once the backup time of the high-power UPS is too long, hundreds of batteries will be used for power supply, forming a series and parallel use of multiple batteries. Each battery is a faulty unit for the entire system. Once a battery is damaged, a set of batteries will quickly become damaged.

The longer the time, the more faulty units there are, and the lower the reliability of the system. According to statistics, 80% of the failures of UPS systems come from batteries.

b) The longer the backup period, the greater the proportion of funds used to purchase batteries. Taking 60kvaups as an example, the 8-hour battery is 50% of the whole device, and the battery is a consumable, which must be replaced in 3-5 years, resulting in a waste of money.

This is determined by the battery, not by the UPS. If it is the kind of small UPS battery in it, it is generally within half an hour.

UPS is just a conversion device and does not produce energy.

When the mains power is normal, the battery inside is charging, and after the power failure, the direct current of the battery is discharged to the load through the UPS, and the energy is from the battery to the load. Conservation of energy.

For example, a group of 12V 100Ah 30 batteries, connected to UPS, and the load is 10KW, then the discharge current can be calculated

10000 (12*30) = current, about 30A, 100Ah battery, discharge, check the graph:

It is about the position of the red dot in the figure above, which corresponds to about the hour.

OK, that's how it works, and it can be done for other batteries. It is important to know the coefficient of the discharge current divided by the battery capacity, which is the one in the above example, this, c represents the nominal capacity of the battery, e.g. 100ah. Small UPS is often the discharge current of or, so the backup time is relatively short.

UPS power supply refers to uninterruptible power supply, full name in English: uninterruptible power system. UPS power supply is a kind of uninterruptible power supply with constant voltage and constant frequency containing energy storage device and inverter as the main component.

It is mainly used to provide uninterrupted power to a single computer, computer network system or other power electronic equipment**. When the mains input is normal, UPS will stabilize the mains voltage to the load, and the UPS at this time is an AC mains regulator, and it also charges the battery in the machine; When the mains power is interrupted (accidental power outage), UPS immediately converts the power of the battery in the machine to the load through inverter conversion**220V alternating current, so that the load can maintain normal operation and protect the load software and hardware from damage. UPS devices are often protected against both over-voltage and under-voltage.

UPS power supply does not say how many hours of capping, the longer the delay time, the more configuration, the more expensive, generally outrageous delay time** can not accept, the general commonly used delay time is the majority of hours, some are used to store stand-alone data for 5-30 minutes, according to their own on-site electricity environment and the recovery time after the mains power interruption to configure the delay time that is more suitable for their own best.

The time that the UPS power supply can be used is related to the battery you configure, the more batteries the larger the ah, the longer the delay, but generally the extension time should not exceed eight hours.

Don't talk nonsense on the first floor, people's power is 8000W, you let the UPS burn with 2000W, don't you pay.

You need to use a minimum of 10000-12000W UPS, and the amount of a battery depends on your power supply time.

If you only need UPS to work for 1 hour, you can choose 12V100AH battery 10 sections.

Each battery: 12V x100ah=1200W10 cells: 1200W x 10=12000W due to UPSand so on power efficiency only.

12000w x w

This will be able to satisfy your 8000w in an hour.

Generally, the actual power of UPS is only about nominal, according to your current power consumption, you can divide 8000 to know how big UPS to match! 8000*, that is, you have to have a 13 kW UPS!! Generally, 6 kilowatt UPS is 192 volt power supply, that is, 16 12 batteries are connected in series!

I have a 15 kW UPS at work, and it is equipped with 16 12V 100Ah batteries!!

UPS power total electrical power power power factor, power factor is generally.

1K can be used for 1 hour, Burke HS-2K can be used, with 3 65 Ah batteries.

You can't afford these devices with this UPS, you can buy another one in series, the battery should be matched according to your backup time, the calculation method you can go to Guangzhou Boke** to see, where the calculation formula.

The actual power of the 6000VA head is 6000 * 07 = 4200W The actual power that is to say that 6000VA can actually only bring 4200W equipment, in the view of Harbin Jixing Electronics, the power of each computer is about 300W, 4200W 300W = 14 units, so the number of computers is only 14 units, Harbin Jixing Electronics is the DC power supply of power * 07 192 = battery capacity, 6000 * That is to say, the 24ah battery can last for an hour.

Hello landlord! 6000w Shante nose? Based on the information you provide you, we will sort the head capacity:

8000VA battery: 16 x 12V24Ah batteries Backup time 30 minutes Power per computer: 300W The approximate calculation results can bring 40 such computers.

The power of the UPS power supply should be determined according to the load and the delay.

1. Load. Determine how much load you need to solve the problem that can be driven.

2. Time delay. Delay refers to the question of how long the power can be supplied after the mains power is interrupted. In the case of a given load and UPS power, how long the delay depends on the capacity of the power supply battery, the longer the delay, the greater the capacity of the required battery, which also means that the investment is increased.

With a load of 3000 watts, using a 100ah 12 volt battery, 16 cells in series for 192 volts calculation: 3000 192 , 100 (ah) hours), it can supply power for 6 hours and 24 minutes.

UPS uninterruptible power supply equipment: power supply equipment that can always be used to protect the instrument.

First, first of all, the power supply of UPS is determined by the load of the equipment, what is the total power of all the equipment that uses UPS? Because UPS is determined according to how much load is used, how big the load is used by how big the UPS host. Therefore, with a set of UPS, we must first determine a few points of the master:

1. What is the power of all the equipment that uses UPS? 2. What is the required input and output voltage? 3. What is the required backup battery life?

The main thing is to know these three conditions to match a set of UPS power supply. In addition, it should be noted that if the equipment load is with inductive load, then the UPS used will be larger, generally speaking, the compressor and motor are inductive loads.

Second, know the power of the equipment to know that is matched with the model of the host, because if you are not sure what model of the host to use, the backup battery life is used in the back of the battery is not known how much, as long as the model of the host is determined, you can calculate the required capacity of the battery, the battery is to determine the length of the backup battery life, you can use this formula to calculate the battery capacity: (the rated capacity of the host * the required backup battery life) divided by (the battery voltage required by the host) =The capacity of the battery. This formula is only a rough calculation of how much battery capacity is needed.

Generally, UPS batteries use 12V.

Third, sometimes with a set of UPS power supply, generally speaking, it is best to ask professionals to go to see now, because it is best to understand the situation on the spot, after all, some places are not in place to see the scene, such as the difference in the size of the site, as well as the site environment, how to place UPS, etc., these are more important, as long as you understand the scene, so as to make a more suitable plan.
