On its face value, a UPS battery backup power system is one that offers power facilities for a sustained period of time, long enough for a piece of equipment or device to safely shut down in case the main power system collapses. It helps to prevent loss of valuable data and work and at the same time, reduces the pressure a hard shutdown can cause on electrical equipment. A UPS carries out functions similar to a surge protector. It protects connected devices from power issues caused by surges or irregular voltages, which can shorten their lifespan and performance. When asking “How do you choose a UPS?”, it is critical to keep the following points in mind.
How to choose a UPS: 5 points to consider
1. Number of outlets
A UPS comes with multiple outlets. That is why, when choosing a UPS, it is important to define the number of devices that need to be connected to it. For homes or small offices, the devices that mandate the need for UPS connections are commonly a router, modem, and occasionally a mini server. Conversely, for larger businesses that require an industrial UPS, the necessity for electric support will be significantly higher. As a general consensus, it is a safe idea to choose a system which has a number of outlets which is greater than the actual requirement, as that provides emergency support as well.
2. Amount of power required by appliances connected
If devices require more power than the UPS can generate, then devices would not be able to operate, regardless of the battery having a substantial amount of energy remaining. It is comparable to a computer’s power management system. If the wattage is lower than what the computer needs, it is a problem.
3. Battery running time
When choosing a UPS, while it is important to evaluate the amount of power required, it is equally imperative to examine the amount of time a user expects his or her UPS to operate during a blackout or power failure. Some users only need back-UPS for just a few minutes, to save some critical work and then effectively shut down the system without any risk of damage. On the other hand, some users require the system to operate during a period of power outage. That is why it is important for a user to understand their own requirements before installing a back UPS.
4. Performance
There is a wide range of back-UPS options to choose from, all of which offer unique features. Even the most standard consumer-level models provide features such as disconnecting battery notifications, USB connectivity, and a software suite that can be administered via computer to personalise settings while viewing power usage.
5. Warranty
A UPS in typical conditions has a lifespan identical to that of its internal battery, which can last for two to three years. Batteries normally degenerate over time, especially when they are fully charged. UPS batteries—in their default state—remain charged all the time. Probably, all warranties are around the three-year mark—an ideal time period to cover the lifespan of the battery. However, in a few cases, some UPSs offer insurance above 3-year warranty.
Homes, small offices, or large-scale organisations, reliable and efficient back-UPS or smart UPS is a significant aspect that one should look for. There are multiple electrical management brands like Schneider Electric that offers products in this domain.
