UPS Uninterruptible Power Supplies

A UPS (uninterruptible power supply) is a power electronics device that continues to supply the connected load from its battery when the mains fails or the voltage goes out of limits. It is used to prevent data loss and downtime in loads that cannot tolerate interruption, such as servers, data centers, medical devices, security and automation systems. This category includes the online UPS and line interactive UPS subgroups, as well as Schneider Electric Easy UPS series devices and accessories such as battery modules, battery cabinets and network cards; the products are from Schneider Electric, Siel and ABB. Besides single-phase 1 kVA and 3 kVA devices, there are three-phase systems with power ratings such as 10 kVA, 100 kVA and 160 kVA. Choose the UPS by the total power of the load (VA and W), input-output phase configuration (1ph/1ph, 3ph/1ph or 3ph/3ph), topology, the battery runtime required, and tower or rack mounting. In an online design the load is continuously supplied by the inverter, so there is no transfer time during an outage; in a line interactive design the load is normally supplied from the mains and switches to the battery with a short transfer time during an outage.
