Guaranteed uninterruptible power supply system is the system that normally provides power from the power source (with the suppression of RF interference, stabilize output voltage and frequency), and also are protected from damage that can cause workis complexes of different types of failures of centralized power.
For all the hardware there are a number following power problems, such as:
To solve these problems with power sets an uninterruptible power supply (UPS), which are based on three topologies:
Offline UPS - designed mainly to protect personal computers from the outage, failure, and Surge. In normal mode, so the UPS supplies power to the load directly from the network - with filtration, but without the active transformation. UPS battery recharged from the mains. In the case of disconnection or vibrations mains UPS provides load stable power supply by battery life.
Line - Interactive UPS is used to protect corporate networks and IT systems of the outage, failure, and the surge, as well as the low and high voltage. In normal mode, linearly - interactive UPS are controlled by a microprocessor, which monitors the quality of the supply voltage, and responds to any of its changes. Chains of compensation are activated in the event of any changes, ensuring its stabilization.
UPS double conversion voltage is used for continuous protection of critical equipment from all power problems (dropout, failure, surge of voltage, low or high voltage level, failures related to switching transients, electromagnetic and radio frequency interference and harmonic distortion).Double conversion technology provides continuous adjustment of output voltage and the ability to perform maintenance or repairs. Power is generated by converting from AC to DC and back.
