Answers to frequently asked questions

Can I connect an entire computer system with a monitor to this UPS?

Yes, the APC Back-UPS Pro BR900G-GR UPS with 900 VA and 540 W of power generally allows you to connect a computer and a monitor, but we recommend that the total consumption of the connected equipment does not exceed the maximum stated power.

How long does a UPS provide power during a power outage?

The actual duration of the power supply depends on the load - with a moderate load, such as a standard computer with a monitor, you can expect a few minutes, which is enough to safely save your work and shut down the system.

Yes, this model has five Schuko sockets, allowing direct use with existing devices in Slovenian households or offices.

How do I know that the UPS is properly protected against power surges?

The APC Back-UPS Pro BR900G-GR has built-in protection against the most common electrical disturbances and visually displays status and errors via an LED display on the chassis.

What happens if multiple devices are connected at the same time?

If the total consumption of the connected devices is higher than the UPS power, an overload alarm will be triggered, in which case the redundant equipment must be removed.
