Uninterruptible Power Supply CyberPower VP700ELCD:The worst thing that can happen to you when you work on a computer is a power outage a few seconds before you finished working. Your document has disappeared, and you have to start again from scratch. Such tragic scenarios can be forestalled by the CyberPower VP700ELCD backup source, or UPS. In principle, this hardware is just a premium battery backup that powers all types of computers and devices that need electricity to function. The CyberPower VP700ELCD UPS battery backup uses the Line interactive design approach. Off-line is classified as the most basic form in case of a black-out, since it switches power to the UPS unit itself. The line interactive UPS also adds voltage regulation to guard against dangerous surges and spikes. CyberPower VP700ELCD Backup Power Supply Key Features Backup power design: Line interactive Actual performance: 700 W UPC operation at full load for 1 min A key attribute is how long the UPS will function when the electricity is off. This depends on the power consumption of the connected electronics – for example, at half-load (50%), the run time will last a longer amount of time. The load of the backup source governs the operating time, which at full load is 1 min and at half-load, its 10 min. It is therefore necessary to determine the energy consumption of the connected appliances and it is best to have a bit of energy extra left. The CyberPower VP700ELCD measures the apparent power as 390, but in reality, the actual power usage is 700 W.
