What is the role of ups?
Unstable power quality can disrupt the normal operation of the computer. In addition to supplying power when the mains voltage is lost, the UPS provides stable and high-quality power in normal conditions. It improves the quality of electricity received from the network, through regulation and filtering, as well as suppression of pulsed interference caused by lightning. UPS can be compared to an individual insurance policy that protects your computer from the risks associated with nutrition.
How many type of UPS?
There are three types of UPS: Off-Line (backup type), On-Line (active type) and linear-interactive.
What size UPS should I choose?
If the power requirements of your equipment are listed in units other than Volt-Amps (VA), convert Watts (W) or Amps (A) into VA by doing the calculations below. Note: The below equation only calculates the maximum amount of VA that the equipment can use, not what is typically used by the equipment at any one time. Users should expect usage requirements to be approximately 60% of below value.
Second, estimate the power requirements as follows:
What is specific gravity, and why does it matter?
Sulfuric acid is no more than chemicals dissolved into a water based solution. Pure distilled water has a specific gravity, or weight of 1.000. When we dissolve chemicals in that water, the solution becomes heavier. Battery electrolyte is a solution of water and sulfuric acid with a specific gravity of 1.265 for flooded batteries and around 1.310 for sealed (absorbed glass mat) batteries. Which means that with AGM batteries, the acid solution is 1.310 times heaver than water alone. The specific gravity can be easily measured with the use of a battery hydrometer, nothing more than a tube with a calibrated float inside. The higher the specific gravity of the solution in the tube, the higher the float will ride in the solution. Just as you are more buoyant in salt water than fresh, the salt being like the dissolved chemical in the water. With that said, as a battery becomes discharged, the dissolved chemical clings to the lead plates. When the battery is charged, it returns to the water. When this becomes hardened on the plates, it is called sulfation.
