The worst thing that can happen to you when you work on a computer is a power outage a few seconds before you wanted to save your work. Your document has disappeared, and you have to start again from scratch. Such catastrophic scenarios can be prevented by the APC Back-UPS PRO BR-900VA backup power supply. This hardware is practically a battery reservoir that powers all devices that need electricity. The APC Back-UPS PRO BR-900VA backup power has the Line interactive design approach. Off-line is classified as the simplest form in case of a outage, since it switches to the internal battery for electric power. The line interactive UPS also adds data line surge suppression to prevent damage from dangerous surges and spikes.
The most important attribute is the battery run time. This is governed by the energy consumption – for example, at half-load (50%), the battery backup time will be three times longer. The load of the backup source defines the operating time, which at full load (100%) is 2,5 min and at a load of 50%, it's 11,4 min. It is therefore essential to estimate the energy consumption of the connected electronics and it is best to have some spare energy in reserve. The APC Back-UPS PRO BR-900VA shows the apparent power as 900, but with realistic use, the actual power usage is 540 W.
