Smart-UPS protect data by supplying network-grade battery backup when power fails. Computer hardware is protected and system life extended through superior full-time multistage surge suppression and noise filtering. The Smart-UPS can switch to on-battery operation as a result of power disturbances or software initiated commands. There is a common misperception that a Smart-UPS will use its battery based only on voltage fluctuations. The following list provides the possible causes for a Smart-UPS switching to battery operation, along with a brief definition of each. No Voltage (Blackout): A total loss of utility power. Low Voltage (Brownout): A decrease in voltage levels. High Voltage (Over Voltage): A surge is a short-term increase in voltage. A spike is an instantaneous dramatic increase in voltage. Total Harmonic Distortion (THD): Periodic distortion of the sine wave. Harmonics add to the fundamental frequency in magnitude. Change in Voltage (dv/dt): Rapidly changing voltage. If the
