‘Topology’ refers to the layout of a system - the way in which constituent parts are interrelated or arranged.
UPS Topology relates to the components and internal wiring used by a UPS device to deliver its power protection. Determining which Topology you should use is based on two main factors: the type of equipment you need to protect, and the importance of that equipment in maintaining your critical business operations.
Line-interactive UPS systems typically transfer from mainstream supply to battery-derived power within two to six milliseconds, which is more than fast enough to keep all but a small percentage of the most power-sensitive equipment operating without interruption. Line Interactive Topology is widely used in IT Server & Communication Room applications, supporting Business-grade Servers, Storage, CCTV, POS and Networking equipment. Smaller units are also found around the home supporting Home Office PC’s and peripherals.
Double conversion online topology is preferred for highly critical loads that are very sensitive to power fluctuations. Double Conversion On-line UPS systems have ZERO transfer time because the inverter is already supplying the connected equipment load when an outage occurs.
Double Conversion Online Topology is essential for medical environments where instantaneous protection is critical. Double Conversion Online topology is also very prevalent in industrial environments supporting production and manufacturing lines, remote and harsh power environments found in the Roads and Rail transport sector and Oil and Gas applications.
