Smart UPS – help deal with the classification of speaking about the standard classification of uninterruptible power supply units of small capacity (up to 5000VA), we note the following classes of equipment: system standby, line-interactive (and so simple called "advanced)" and the models developed using the technology on-line. In addition to this global typology, every self-respecting producer brings to market their names and their classification unit. Smart ups – this is a collective image of the entire line of uninterruptible power supply APS. Initially, this software company is almost entirely focused on the issue of line-interactive uninterruptible power supply units so line of smart-ups initially reported as only line-interactive. Internal "watershed" in the UPS brand Smart-ups took place between budget versions and models of a higher class. If we are talking about the budget version of the smart-ups, then the output waveform at them – approximated (step) sine wave, while more expensive options smart-ups expected output in the form of truncated trapezoid, ie, closer closer to the ideal sine wave.

Long enough for APC pursued a policy of refusal of entry to online uninterruptible power supplies, including made statements that in some cases, the user is not an obvious necessity. But the later part power sources in the line of smart-ups (only the higher price range) were performed by online technology. Now it makes sense to mention one of the most popular and promote solutions from APC – InfrStruXure. This is a "Set-designer" standardized parts. It uses Smart-ups configuration RM.
