Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Outlets : the number and type of outlets (Schuko, IEC) vary between versions of a single photographed series.
  • Options : LCD display, USB or RJ45 port, SNMP network card and rack kit are supplied only if the specifications say so.
  • Batteries : the additional battery modules photographed next to the UPS are sold separately.
  • Runtime : it depends on the load actually plugged in, never on what the image shows.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Product overview

A desktop UPS to protect a computer and its peripherals: line-interactive with voltage regulation and 900 VA / 540 W.
Technology & protection: it takes over on battery the moment the power fails, absorbs surges and corrects voltage dips and spikes without using the battery.
Power: 900 VA for 540 W of usable power — a PC, a monitor and their accessories.
Runtime: about 11 minutes at half load (270 W), 6 minutes at 70%.
Outlets: 6 C13 outlets (computer and server power cords).
LCD display: shows load, battery level and remaining runtime at a glance — so you can monitor the UPS without any software.
Ideal, for example, for a desktop PC, a monitor or a small NAS.
Remember to check how much power your equipment draws and to choose the rating according to the runtime you need.

Frequently asked questions about this product

How long does the BR900MI run on battery?
11 minutes at 50% load, i.e. 270 W, and 6 minutes at 70%, i.e. 378 W. A full recharge, on the other hand, takes 12 hours: that is long, and worth knowing if power cuts come one after another.
Are all six outlets on the BR900MI battery-backed?
Yes, all six C13 outlets are powered by the battery. Plan for IEC power cords: there is no household socket on this unit, and its input is IEC as well.
What does the BR900MI display show?
A multifunction LCD display shows the load, the battery level and the remaining runtime — without installing any software. This is what sets the Back-UPS Pro series apart from models with simple indicator lights.
What waveform does the BR900MI output?
A stepped approximation to a sine wave, built up in steps, not a pure sine wave. Switchover takes 10 milliseconds typical, 12 at most — slightly slower than the average for the category.
How much load can this 900 VA unit handle?
540 W. This wattage figure is the one to compare with your computer workstation and its peripherals. The UPS also dissipates only 16.4 BTU per hour: it produces very little heat.
Can the BR900MI battery be replaced?
Yes, under the reference APCRBC164. It is rated for 3 to 5 years of service: after a few years it is the battery you replace, not the UPS.
How much space does the BR900MI take up, and is it noisy?
9.1 cm wide, 31 cm deep and 19 cm high, weighing 7.1 kg: a slim tower format that is easy to slip behind a desktop tower. It is rated at 45 dBA.
Is the APC Back-UPS Pro BR900MI new and under warranty?
Yes, new equipment, with the invoice serving as the warranty document, for a period of 2 years. It is CE, C-Tick, EAC and RCM certified, and connects to the computer through a USB port for automatic shutdown. The datasheet covers the rest.
