Question:

Ups model problem

What is the general type of computer ups UPS type? Rated Capacity? voltage range? Frequency Range? Output voltage range? Power factor And so on, how to know and their machine with unworthy? How big is it?

Answer:

Rated Capacity? UPS rated capacity of the actual model prevail. General household type: 500VA / 300W; 1000VA / 600w. Medium-sized UPS can be 10KVA / 7KW, large UPS can reach hundreds of KVA or even a few trillion VA. voltage range? The general voltage range of not less than 220 plus or minus 20% Frequency Range? Frequency range is generally 50Hz plus or minus 3Hz above, beyond this range is the battery power supply Output voltage range? General backup UPS output voltage range of 220 positive and negative about 5V, on-line general accuracy within 1V Power factor The power factor is divided into the input power factor and the output power factor. The meaning is the angle between the voltage waveform and the current waveform. The general design of the power factor is better, the general design standard is 0.7 (frequency machine) ~ 0.99 (high frequency machine), the output power factor depending on the load may not necessarily the bigger the better, the general design standard is (0.7,0.8). And so on, how to know and their machine with unworthy? How big is it? General personal use UPS, the choice of backup can be a single PC optional capacity of 500VA, two PC is selected 1000VA. For more power, you should consider the choice of more than 1000KVA online UPS, the specific query to the manufacturers. Recommended to consider the choice of brand-name products
What is the general type of computer ups A: The general computer can use the backup UPS, different manufacturers naming the way is not the same, the general price is less than 500 are. UPS type? A: UPS mainly back-up, online interactive, online three. Backup power in the city when the normal power regulator after the output, the mains by the battery inverter power supply output, backup UPS features simple structure, high efficiency, low efficiency, switching time, cheap , Generally applied to personal computers. Online interactive work mode similar to the backup, the main difference is the use of two-way inverter, the inverter can charge the battery can also be inverter output. On-line, currently the most widely used UPS architecture, the electricity is normal, UPS will rectify the electricity into DC, the battery pack to charge, while the inverter will be converted into pure DC AC power. When the utility power is abnormal, the DC power is supplied from the battery pack to the inverter, and the AC power is output. On-line UPS is characterized by high inverter efficiency, high output waveform accuracy, wide range of utility power, switching time is short (generally can do 0MS).
Now the computer is very adaptable, UPS rarely used.
