Series XC - The Ultimate in Power Conditioning Reliability

XC Guideform Specification

Large Rotary Uninterruptible Power Supply Cut Sheet

System Description

The Series XC motor-generator set absorbs load harmonics and produces a pure sine-wave output, ideal for any critical load. By operating the rectifier/charger and inverter in series as the primary power path, the Series XC Hybrid™ UPS continuously tests its most critical components under actual operating conditions. There is no delay, no transients, no question when the utility source fails; transfer to battery and to alternate AC source is seamless. The reliability of those components to perform in a power outage is constantly being verified. By providing a physical air gap between the load and the utility source, the motor-generator set protects the critical load from high power transients, including lightning.

Lower Cost To Operate

The greater reliability of the Series XC Hybrid™ UPS significantly reduces the cost of ownership, and it virtually eliminates costly power disruptions. The Hybrid™ UPS is less expensive to operate because no air-conditioning is required

Design Features

• Fully automated mode selection - full UPS/Rotating Filter/Load On Utility/System Off
• Synchronized mode change without load disruption
• Four-line alpha-numeric display - shows critical metering and status/fault indication including: voltage, current, PF, Frequency, power and efficiency
• Silver-plated copper bus - reduces cabling, connections and hardware
• N+1 redundancy
• Battery operation on utility loss
• Complete system shutdown and isolation in emergency
• Input current limit and battery current limit for maintenance-free battery
