Home computer UPS uninterruptible power supply needs much

Home computer UPS uninterruptible power supply needs much

Answer:

Home desktop computer uninterrupted UPS generally use 300W-500W on it. 1, UPS power supply the greater the natural price of the higher. 2, the longer the battery life longer, and the battery is very heavy. 3, home computer using 500W UPS, the battery is 12V 9Ah, desktop machines can be used for about 20 minutes. 4, uninterrupted UPS is that the desktop power loss will be a sudden loss of data, for software creation, drawing, document editing work, it is not power. So you can choose UPS to maintain power supply. 5, UPS battery capacity is limited, after a power outage, it is necessary to keep the computer work, and then shut down normally. If you need UPS battery for a long time power supply, the need for large capacity battery pack, the higher the cost of a large volume. 6, the battery capacity calculation, such as 12V 9AH battery, the storage capacity is 12 * 9 = 108Wh, which is about 0.1 kWh. The battery can supply 100W of electrical work for 1 hour, in fact, UPS inverter efficiency can not be 100%, so the time to make a discount.
Home use, or choose a backup with a regulator of 500VA, the effective power is 350W, home computer enough, backup time is mainly based on the battery to set, if the voltage is often unstable, then select the built-in 7AH battery, the quality of reliable price Most of the number of about 200, I hope my answer can help you!
To use 500VA UPS, but the backup time is very short, only about ten minutes seems to have no 300W UPS
