What Does UPS for Computers Stand For? In com...
The vast majority of UPS in use today store their energy in sealed valve-regulated lead-acid batteries (SVRLAs).
Two UPS technologies dominate, ‘on-line’ and ‘off-line’. Almost all units described by their manufacturers as being ‘line interactive’ are off-line units but with the addition of an Automatic Voltage Regulation (AVR) transformer.
The description ‘on-line/off-line’ simply indicates whether the inverter (that part of the UPS that converts the DC provided by the batteries to the AC that we use from a wall socket) is on-line or off-line during normal use. Almost all UPS rated at 10kVA and over are on-line.
These UPS offer enhanced power protection over the basic off-line designs because they provide additional line conditioning. They can also cope with a wider range of input voltages without resorting to the battery.
With an understanding of the need for power saving within Data Centres, and having tracked the latest developments in off-line UPS technology, UPS Systems have now become the sole UK distributor of PureWave UPS products from S&C Electric in Canada.
PureWave is a high-capacity, off-line, immediate-discharge UPS that provides power protection to entire facilities served by a single source. Its modular structure supports Data Centre loads between 313kVA and 20MVA, protecting the power sensitive equipment from voltage sags, surges, transients, momentary disruptions and complete outages.
