The Avaya Online UPS: How it Works www.powerware.com/avaya Copyright© 2003 Avaya Inc. All rights reserved The Online UPS Essentially, there are 9 basic power problems that can damage your telecommunications equipment: How does Avaya’s online UPS prevent these problems from reaching your equipment and Power Failure Power Sags Power Surges deliver clean, regulated power? Brownouts Line noise High Voltage Frequency Switching Spikes Variation Transients Harmonic Distortion Click to continue Online UPS Circuitry An online UPS isolates connected equipment Internal Automatic Bypass from power problems by completely regenerating the incoming alternating current (AC). AC to DC DC to AC Rectifier Raw Utility (Incoming AC) Inverter Clean AC Output to Load Filtering & Surge Suppression Battery Charger Line diagram of online UPS circuitry Battery Click to continue Converting AC to DC Internal Automatic Bypass Raw Utility (Incoming AC) AC to DC Rectifier DC to AC Inverter Clean AC Output to Load Filtering & Surge Suppression Bi-Directional Power Converter First, incoming AC is filtered and converted to DC. Battery Click to continue Battery Charging Internal Automatic Bypass Raw Utility (Incoming AC) AC to DC Rectifier DC to AC Inverter Clean AC Output to Load Filtering & Surge Suppression Battery Charger A small portion of this DC power is used to charge the battery. Battery Click to continue AC Power to the Load Internal Automatic Bypass Raw Utility (Incoming AC) AC to DC Rectifier DC to AC Inverter Clean AC Output to Load Filtering & Surge Suppression The DC power is then converted back to AC power and out to the load. Bi-Directional Power Converter Battery Click to continue The Result? By regenerating the incoming utility, power problems are completely removed. The connected load always receives clean, sine wave power.
