APC Back-UPS BE-850VA Backup Power Supply Key Features

• Type of backup power supply: Off-line
• Actual performance: 520 W
• UPC operation at full load for 2,3 min

A key parameter is how long the UPS will function when the electricity is off. This depends on 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 maximum load is 2,3 min and at half the energy consumption, it is 9,8 min. It is therefore essential to determine the power consumption of the connected electronics and it is a good idea to have some spare energy in reserve. The APC Back-UPS BE-850VA measures the apparent power as 850, but with realistic use, the actual power usage is 520 W.
