Critical Power UltraStar 3-Phase UPS Systems

The Critical Power UltraStar 3-Phase UPS utilizes a double conversion design to ensure the maximum possible power protection. The Critical Power UltraStar UPS completely regenerates the power thereby providing a clean stable sine wave to the critical load. The UPS output power is closely regulated to compensate for any utility voltage anomalies. In addition, the UPS voltage is held constant during all load variations. In the event of a total power outage the UPS seamlessly draws power from the batteries. The UPS power status can be monitored through the front panel display.
