How is ups efficiency calculated?

Dec , 09 2023

UPS efficiency is a big deal. The more efficient your UPS, the cheaper it is to run. As energy costs continue to increase, we’ve seen that businesses and organisations across multiple sectors are now looking for ways to increase their energy efficiency and subsequently reduce their energy bills. One of the ways to do this is by investing in an efficient uninterruptible power supply (UPS). What is ...

What is UPS ECO mode in UPS system?

Dec , 15 2023

As good as this may sound, hardly any data centres choose to use ups eco mode. Because this mode doesn’t offer the same level of protection as a true on-line uninterruptible power supply. Also known as ‘economy’, UPS ECO mode is a special UPS operating mode offering enhanced energy efficiency. Capable of delivering efficiency up to 99%, ECO mode sees the bypass line (raw mains supply) power the lo...

Working principle of lead-acid battery

Dec , 23 2023

1. The generation of electromotive force of lead-acid batteries After the lead-acid battery is charged, the positive plate lead dioxide (PbO2), under the action of water molecules in the sulfuric acid solution, a small amount of lead dioxide and water produce dissociable unstable substances - lead hydroxide (Pb (OH) 4), hydroxide ions in the solution, lead ions (Pb4) remain on the positive plate, ...

Basic knowledge of maintenance-free lead-acid batteries

Dec , 23 2023

1. Meaning of maintenance-free battery The main advantage of the valve-controlled lead-acid battery is that the oxygen generated on the positive plate during charging is reduced to water on the negative plate through the recombination reaction, and water does not need to be added during the specified floating life period when used, so it is also called maintenance-free lead-acid battery. It can be...

What is advantage of double conversion ups online

Dec , 29 2023

Double conversion ups stands for uninterrupted power supply provides backup when the usual source of power fails. It is also known as battery backup. All kinds of electronic gadgets require a power supply for their working process. Electricity can run out anytime because of any shortage or failure. Thus, it can hamper the performance of several electronic gadgets. So we cannot rely on direct power...
