APC Back-UPS BX 1200VA (FR) Backup Power Supply Key Features Backup power design: Line interactive Actual performance: 900 W At a 100% load, the UPC will work for 1 min 4 classic Schuko plugs The most important attribute is the UPS run time. This depends on the power consumption of the connected appliances – for example, at half-load (50%), the backup time will last a longer amount of time. The load of the UPS governs the operating time, which at maximum load is 1 min and at a load of 50%, its 6,5 min. It is therefore necessary to estimate the power consumption of the connected appliances and ideally to add some spare power left. The APC Back-UPS BX 1200VA (FR) measures the apparent power as 1600, but realistically, the actual power usage is 900 W.
