Uninterruptible Power Supply APC Back-UPS BX 2200VA (IEC):Youve probably already experienced a power supply interruption a few seconds before the entire file was saved. The unsaved work is irretrievably lost, and you must start from scratch. Similar heart-stopping situations can be warded off by the APC Back-UPS BX 2200VA (IEC) backup source, or UPS. This hardware is practically a battery reservoir that powers all types of electronics. The APC Back-UPS BX 2200VA (IEC) UPS has the Line interactive design approach. Off-line is the most basic form when power fails because it switches power to the UPS unit itself. The line interactive UPS also adds power protection to guard against dangerous surges travelling along data lines. APC Back-UPS BX 2200VA (IEC) Backup Power Supply Key Features Backup power design: Line interactive Actual performance: 1200 W At a 100% load, the UPC will work for 1 min 6 sockets (C13), as used for monitors, printers, or amplifiers An important attribute is the UPS run time. This is governed by the power consumption of the connected appliances – for example, at half-load (50%), the run time can last up to three times as long. The load of the backup source governs the operating time, which at full load is 1 min and at half-load, its 8,5 min. It is therefore crucial to estimate the energy consumption of the connected electronics and it is best to have a bit of energy extra left. The APC Back-UPS BX 2200VA (IEC) measures the apparent power as 2200, but with realistic use, the actual usage matches the value of 1200 W.
