You've probably already experienced the nightmare of a power supply interruption minutes before you saved that important document. Your work is irretrievably lost, and you must start from scratch. Similar heart-stopping situations can be prevented by the LEGRAND UPS Keor SP 1500VA/900W replacement backup source. This is a premium battery backup that provides power for all appliances needing electricity. The LEGRAND UPS Keor SP 1500VA/900W UPS battery backup features the Line interactive design approach. Off-line is classified as the simplest form when power fails, since it switches to the internal battery for electric power. The line interactive UPS enhances the simpler off-line version of voltage regulation to guard against dangerous surges travelling along data lines.


An important attribute is how long the UPS will function when the electricity is off. This depends on the power consumption of the connected devices – for example, at half-load (50%), the backup time lasts much longer. The load of the backup source defines the operating time, which at full load (100%) is 1 min and at half-load, it's 8 min. It is therefore necessary to determine the power consumption of the connected electronics and ideally to have some extra power left. The LEGRAND UPS Keor SP 1500VA/900W measures the apparent power as 1500, but with realistic use, the actual usage matches the value of 900 W.
