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. 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 systems. Smart-UPS feature a 16-segment LED display, extended range automatic voltage regulation (AVR), and pure sine wave output on battery.
