A UPS (uninterruptible power supplies) is an electrical device that provides emergency power to a system or device when the input power source fails. An uninterruptible power supply can be a life saviour to businesses when the power goes out unexpectedly; it will let you continue to safely close and store any open documents to protect businesses information and future productivity.
A UPS is designed to protect hardware for both homes and businesses where power is unexpected lost. Power problems can and do occur every day, ranging from spikes and surges of power to complete black outs. UPS’s have a range of different benefits to ensure that data and hardware is secure.
UPS’s come in two different formats, single phase and 3 phase. Both are designed to protect business power supplies from unexpected events that can affect technical equipment, but both forms of UPS work for different environments.
A single phase system works by using alternating current electric power in which the voltage and current flow changes in magnitude and direction in a cyclical fashion, typically 60 times per second. Single phase systems refer to the use of a single input source and a single output source (1:1) to electrical equipment, examples of which would include the supply of power from 230/240VAc three-pin UK sockets. Single-phase supplies are used to operate small power hardware such as rack-mounted servers, telecoms, network switches, computer systems or any device running from a standard three-pin UK plug.
A single phase UPS are used in sites/businesses where power requirements are less than 20kVA. They are usually a practical and cost-effective solution to applications with low kVA requirements such as small businesses, homes and satellite offices.
Additionally, single phase plug and play off-line or line-interactive UPS’s are easy to install. The end user often does it during initial PC setup and requires no installation from an outside party.
In 3 phase systems, the power circuit combines three alternating currents that vary in phase by 120 degrees. As a result, the power would never drop to zero, making it possible to carry more load. 3 phase systems refer to the use of all 3 phases which are generated from the National Grid. A 3 phase electrical system refers to an electrical supply comprised of 3 individual sine waves installed as a 3 wire configuration (or 3 wire with a neutral) as input sources to the electrical equipment. The output tends to be 3 phase (3:3) but can also be singular (3:1).
A 3 phase UPS is used for applications with high kVA requirements due to their ability to distribute large quantities of power over a larger area/distance. Their uses are for sites such as data centres, large buildings, industrial facilities and medical or transport-affiliated services and not for smaller businesses and home users.
A UPS is an important tool for all businesses and home users, however deciding which may be most beneficial to you can be difficult. It is important to choose a UPS that will work for you or your business in the future.
