Uninterruptible Power Supply CyberPower VP1200ELCD:Youve probably already experienced a power supply interruption minutes before your work was about to be automatically saved. Your work has gone into the ether, and you have to start again from scratch. Repeats of such tragedies can be forestalled by the CyberPower VP1200ELCD backup source, or UPS. This is just another name for a large battery that powers all types of computers and devices that need electricity to function. The CyberPower VP1200ELCD UPS battery backup has the Line interactive design approach. Off-line is seen as the most basic form in case of a black-out because it connects to the battery and disconnects from the mains power. The line interactive UPS enhances the simpler off-line version of power protection to guard against dangerous surges and spikes. CyberPower VP1200ELCD Backup Power Supply Key Features Type of backup power supply: Line interactive Actual performance: 720 W At a 100% load, the UPC will work for 4 min An important parameter is the UPS run time during outages. This is governed by the power consumption of the connected electronics – for example, at half-load (50%), the UPS power time lasts much longer. The load of the UPS defines the operating time, which at maximum load is 4 min and at half the energy consumption, it is 12 min. It is therefore necessary to calculate the energy consumption of the connected computers, monitors and other electronics and it is best to have some extra power left. The CyberPower VP1200ELCD shows the apparent power as 1200, but realistically, the actual usage matches the value of 720 W.
