APC Back-UPS PRO BR-900VA

You've probably already experienced a power supply interruption a few seconds before your work was about to be automatically saved. The unsaved work is irretrievably lost, and you have to start again from scratch. Such uncomfortable (to put it mildly) situations can be warded off by the APC Back-UPS PRO BR-900VA backup source, or UPS. This is a battery reservoir that provides power for all types of electronics. The APC Back-UPS PRO BR-900VA UPS battery backup has the Line interactive design approach. Off-line is the most basic form when power fails because it connects to the battery and disconnects from the mains power. The line interactive UPS also adds power protection to guard against dangerous surges travelling along data lines.

APC Back-UPS PRO BR-900VA Backup Power Supply Key Features

• Backup power supply type: Line interactive
• Actual performance: 540 W
• At maximum load, the UPC will run for 2,5 min
• 6 connects with C13 sockets, with devices such as monitors, LCD screens and printers

A key attribute is the UPS run time during outages. This is governed by the energy consumption – for example, at half-load (50%), the run time lasts much longer. The load of the backup source determines the operating time, which at full load is 2,5 min and at a load of 50%, it's 11,4 min. It is therefore crucial to calculate the energy consumption of the connected computers, monitors and other electronics and it is a good idea to add some spare power left. The APC Back-UPS PRO BR-900VA specifies the apparent power as 900, but with realistic use, the actual usage matches the value of 540 W.
