The first step when choosing an UPS is to determine the necessary power. To do this, you must add the power consumption of all devices to be connected to the country without interruption – a laptop, monitor, router.
Another important parameter is battery life. Usually 5-10 minutes are enough to complete the work and save all data. However, if you want to continue working while closing the light, it is worth thinking about models with wider batteries that support the work up to one hour and longer.
There are three types of UPS that differ in terms of protection level and working principle. Simple and budget – Reserve (Offline) Models. They only open the battery with a complete connection of electricity, but they do not protect against small voltage jumps. In fact, interactive devices can stabilize the voltage that reduces the abrasion of the battery. The most reliable one is online IBP, which constantly regulates the current but is more expensive. Election depends on needs and budget.
When buying, it is important to pay attention to the number of sockets. It must be sufficient for all devices you plan to connect. Some models are equipped with USB or Ethernet ports to protect environmental devices from parasites. It is also worth considering the noise level: they are almost quiet in the usual IBP mode, but the fan can open while working from the battery, which can distract especially in a quiet room. The service life of the UPS is largely dependent on the battery. Most of the time, lead acid batteries are finally used.
Additional functions such as LCD displays or indicators simplify the use of UPS. They show the current working mode, battery charge and possible problems in the network. Before purchasing, be sure to review user reviews to verify the reliability of the device and the compliance of the declared features. Compare several models, check the warranty time and the usability of the service centers in your area. This will help you select an UPS that protects your technique and data without creating unnecessary difficulties.
