UPS uninterrupted power supply, how long can you extend the power supply?
Generally speaking, the longest UPS can delay 12 hours, even with more batteries, that is, the first discharge time, a long time to later, slowly on the line, the charge itself is not so big
This depends on the power consumption of the electrical equipment and the capacity of the ups reserve battery. Generally sold at around 500 yuan UPS, and then a desktop computer, you can power 10 minutes or so.
The backup UPS general built-in 4AH or 7AH battery, the standby time is fixed; the standard model of online and interactive online UPS with built-in 7AH battery, there are long-term models with a large capacity battery, the user can set equipped with large capacity battery standby time according to the need to achieve.UPS power backup delay time calculation method: (battery capacity, X, battery operating voltage) / equipment power = extended time (hour).
UPS standby time is UPS by the energy storage device is decided, UPS now generally used sealed maintenance free lead-acid battery as energy storage battery capacity by the number of ampere hour (AH) "this index, which means the discharge in accordance with the provisions of the current time. The same voltage of the battery, when a large number of large capacity; the same number of ampere hour battery, voltage high voltage and large capacity, usually with ah. Said the capacity of the battery, such as 12V/7AH, 12V/24AH, 12V/65AH, 12V/100AH.
