Backup Power Supply APC Back-UPS BX 1200VA (IEC):We would not wish it on our worst enemy. A power outage just before your work was about to be automatically saved. Your document has disappeared, and you have to start again from nothing. Such uncomfortable (to put it mildly) situations can be averted by the APC Back-UPS BX 1200VA (IEC) backup source, or UPS. This is just another name for a large battery that powers all devices that need electricity. The APC Back-UPS BX 1200VA (IEC) UPS has the Line interactive design approach. Off-line is classified as the simplest form in case of a black-out, since it connects to the battery and disconnects from the mains power. The line interactive UPS enhances the simpler off-line version of voltage regulation to prevent damage from dangerous surges and spikes. APC Back-UPS BX 1200VA (IEC) Backup Power Supply Key Features Type of backup power supply: Line interactive Actual performance: 650 W At maximum load, the UPC will run for 1 min 6 sockets (C13), as used for monitors, printers, or amplifiers The most important parameter is the battery run time. 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 (100%) is 1 min and at a load of 50%, its 5 min. It is therefore essential to determine the energy consumption of the connected electronics and it is a good idea to have some extra power left. The APC Back-UPS BX 1200VA (IEC) measures the apparent power as 1200, but with realistic use, the actual power usage is 650 W.
