How big a UPS power supply should I buy

First of all, you must determine how much power your device is, 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.

Secondly, it should be understood that there are two ways to express the rated power of UPS: apparent power (unit VA) and actual output power (unit W), due to the existence of reactive power, which causes this difference, and the conversion relationship between the two is: apparent power * power factor = actual output power.

When configuring UPS for equipment, the actual output power of UPS should be used as the basis for matching, and some dealers intentionally or unintentionally confuse the difference between (VA) and (W), which should be noted by users.

Are all upstairs engaged in UPS? It's all for sale!

1.Shante MT1000 (600W) backup UPS, full load use time of 10 minutes, and your load only use 200VA*, this nominal UPS is completely enough to use for half an hour.

2.Shante C1K (700W)** UPS, and the above use is no different, the only difference is that the backup type has a 10 millisecond conversion time after power failure, which is generally used for personal and some ordinary equipment, with limitations, and the ** type has no conversion time, can be used for any occasion, but ** is higher than the backup type.

C1K: about 1200 yuan.

The above are all authentic Shante original**Please see the trademark "santak" when purchasing, and the other trademarks are non-original,**Generally only use the original 6% off!

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

I want to use a 500VA UPS, but the backup time is very short, only about 10 minutes, and it seems that there is no 300W UPS

If you use it at home, you still choose a backup type with stabilized voltage 500VA, the effective power is 350W, the home computer is enough, the backup time is mainly based on the battery, if the voltage is often unstable, choose the built-in 7ah battery, the quality of reliable ** is mostly about 200, I hope my answer can help you!!

The standard 300w is about 150.

The uninterrupted UPS of home desktop computers generally uses 300W-500W.

1. The greater the power of the UPS power supply, the higher the natural selling price.

2. The longer the battery lasts, the bigger the battery, and the battery is very heavy.

3. The 500W UPS used in the home computer has a battery of 12V 9Ah, and the desktop can be used for about 20 minutes.

4. The significance of uninterruptible UPS lies in the fact that the desktop will lose data due to a sudden power failure, and it cannot be powered off for software creation, drawing, and document work. Therefore, UPS can be selected to maintain power supply.

5. The battery capacity of UPS is limited, and after a power failure, it is necessary to save the work on the computer in time, and then shut down normally.

If you need UPS batteries to supply power for a long time, you need a large-capacity battery pack, which is expensive and large.

6. Calculation of battery capacity, for example, the storage capacity of a 12V 9Ah battery is 12*9=108Wh, which is about the kilowatt-hour of electricity. The battery can supply 100W electrical appliances to work for 1 hour, in fact, the UPS inverter efficiency cannot be 100%, so the time should be discounted.

300w is enough, and that's what I'm using now.
