You can use APC online calculator which indicates the products that meet the load and time required:
APC UPS Selector/Calculator - Find the Correct Battery Backup
Somethings to consider if this is intended for the long term use and integration. If you just want
Something in place any of the APC UPS that meet the run time will suffice. Quite a few of the mid tier units offer USB to PC monitoring which allows you to view metrics and schedule / manage how the UPS will operate given different scenarios.
The upper tier of UPS allow you to install NMC (Network Management Card) which again enables more awareness, integration, and management. The higher tier of UPS allow you to add / chain more battery packs to offer extended their run time. Lots of the newer UPS systems offer
Pure Sine Wave power vs PWM (Pulse Width Modulation) or square wave.
Most electronics operate just fine using PWM as seen in cheaper UPS's.
Having said this, in 2021 it makes little sense to purchase a PWM vs Pure Sine Wave UPS . . .
More expensive UPS also incorporate Active PFC (Power Factor Correction) which allows the equipment to run more efficiently while reducing energy costs. Lastly, more expansive UPS systems offer On-Line power vs cheaper systems Line Interactive power control and supply. Regardless of what type, brand, model, of UPS always insure you validate the UPS will operate as expected during a power failure.
Many systems will refuse to power back up if the battery is completely drained. While other UPS systems will not automatically return to their (Last Known State) and just remain off even if POCO power has been restored. Things to accept is every UPS battery is considered a consumable and wears out even if you don't call it to duty.
Thus, you must always replace the batteries on time / schedule . . .
If money is no object you can never go wrong buying a double conversion on-line UPS!
NOTE: Almost all UPS offer some form of AVR (Automatic Voltage Regulation) which trims / boosts the line voltage. But, not all of them operate as you would expect or offer the same level of protection. Many cheaper AVR UPS will not trim / boost line voltage if said voltage is slow in rise. Other considerations is understanding that not all UPS's will offer true
Brown Out protection (Line Voltage Boost) and remain connected to the POCO instead of transferring to the battery pack.
This can lead to premature failure of electronics . . .
