Over 20 million units sold - the UPS you can trust
APC award-winning Smart-UPS® is the most popular UPS in the world for servers, storage and networks. Trusted to protect critical data and equipment from power problems by supplying clean and reliable network-grade power. In addition to legendary reliability and manageability, Smart-UPS have extremely high efficiency at low, medium and high load levels making them ideal for today's multi-core or virtualized servers that have varying load consumption. Available in a variety of form factors (tower, rack mount, rack/tower convertible) there is a model for every application and budget. Rack mounted Smart-UPS are ideal for powering Blade or density optimized servers in a distributed power protection environment as the primary or redundant protection. Smart-UPS® models have long been considered the benchmark for all network and server UPS's. Smart-UPS feature a 16-segment LED display, extended range automatic voltage regulation (AVR), and pure sine wave output on battery. Additional manageability options are available through the Smart-Slot interface, which is an internal slot for the installation of optional accessory cards. The extended run Smart-UPS XL has the capability to add external battery packs to scale runtime from minutes to hours typically needed for converged voice and data networks. The entry level Smart-UPS SC is an economical choice for small and medium businesses looking to protect small switches, networking devices and point-of-sale (POS) equipment.
