Decide what kind of equipment you want to protect, and how important the possibility of continuous operation is for you. Find out what problems most often arise in the power supply in your home. For the proper UPS management, this is important now.
The range of manufactured UPSs is very wide both in terms of characteristics and price. In order not to make a mistake with the choice, you need to find out what kind of problems there are in the power supply, what kind of failure can be expected, and in accordance with this choose the appropriate type of UPS with a simple, complex or super-sophisticated degree of protection.
Buy a UPS whose capacity is 20-30% higher than the capacity of your system
When choosing one or another UPS, you should focus on the technical characteristics of the protected equipment, the main of which is power. Connecting a computer whose power exceeds the rated power of the UPS itself will overload the uninterruptible power supply, turn it off and, as a result, turn off the computer itself. To avoid this, you need to know the power of the equipment connected to the UPS and select a UPS whose rated power is greater than the maximum load power. It is desirable that the power of the UPS is 20-30% higher than the capacity of the protected equipment. So, if the power of your equipment is 750 VA, then the power of the UPS should not be lower than 1000 VA (1 kVA).
Determine how much battery life you need
The average battery life is 5-7 minutes, as a rule, this is enough to save all open documents and correctly complete the work. But if you need more time to automatically close very complex systems, you can easily select the appropriate UPS depending on the system parameters.
Choose a UPS with software
Such software displays the parameters of the mains and the status of the UPS, and during a prolonged network failure automatically saves all data in open applications. This convenient function allows you to not lose information, even if you were not near the computer during a power outage.
Buy UPSs that have enough outlets for peripherals and have connectors to protect the telephone line
Users usually use UPSs to protect not only PCs but also peripheral equipment. If you plan to connect various devices to the UPS (monitor, printer, etc.), make sure that the uninterruptible power supply has special outlets with protection against power surges. With modems and faxes, it is good for the UPS to protect the telephone line.
Before buying a UPS, decide where it will be located in the apartment
When buying a UPS, it is necessary to take into account such a parameter as noise and think in advance about the location of the source. A battery-powered UPS generates about 40-45 decibels at a distance of 1 m from the UPS, which can cause irritation. Therefore, it is not recommended to place a working source in the bedroom. If necessary, to reduce noise, place the UPS behind a partition and not next to the bed, while observing the conditions for efficient cooling of the UPS.
Buy UPSs with clear displays and controls
Each user is pleased when information about the operation of the system comes to him in an understandable and convenient form. All UPSs inform the user via beeps, for example, about switching to battery mode. In addition, the UPSs have LED indicators that indicate various conditions, including freelance ones, for example, if it is necessary to replace the battery.
