The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

A UPS designed for powering DC equipment is very similar to an online UPS, except that it does not need an output inverter. Also, if the UPS's battery voltage is matched with the voltage the device needs, the device's power supply will not be needed either. Since one or more power conversion steps are eliminated, this increases efficiency and ...
APC Smart-UPS is a line of smaller units intended for home and office use, available as floor-standing and rackmount versions. With the exception of the Smart-UPS Online series (SURT and SRT models), Smart-UPS units are line-interactive UPS systems, running their outputs off the inverters only when the grid power is unavailable.
Telephone system central offices contain large battery systems to provide power for customer telephones, telephone switches, and related apparatus.

Direct current data centers are data centers that produce direct current on site with solar panels and store the electricity on site in a battery storage power station. Computers run on direct current and the need for inverting the AC power from the grid would be eliminated. The data center site could still use AC power as a grid-as-a-backup ...
[26] [27] [28] Subsequent flare-ups occurred; the epidemic was finally declared over on 9 June 2016, 42 days after the last case tested negative on 28 April 2016 in Monrovia.

The F-Series was first introduced in 1948 as a replacement for a previous pickup model line based on car platforms. The most popular version of the model line is the F-150 pickup truck (since 1975), currently in its fourteenth generation (introduced for the 2021 model year). From 1953 to 1983, the entry-level F-Series pickup was the 1 ⁄ 2 ton ...
Though tensions had existed between Georgia and Russia for years and more intensively since the Rose Revolution, the diplomatic crisis increased significantly in the spring of 2008, namely after Western powers recognized the independence of Kosovo in February and following Georgian attempts to gain a NATO Membership Action Plan at the 2008 Bucharest Summit; and while the eventual war saw a ...
