To those who only view the Series XC from the outside, it looks very much like the original XC in 1990. Externally, only the analog meters have been replaced by a digital metering panel. But within the XC’s sheet metal, dramatic changes are occurring.

Each change has been carefully engineered to improve reliability and performance. These changes are designed to blend into the XC, not cause obsolescence. The XC leads the UPS industry to reliability, and this evolution is quietly increasing that lead. This increasing reliability is the result of better components, fewer connections, and redundancy in critical areas.

This evolution began when the Digital Rectifier Board (Early 1992) was installed in the XC. It replaced eight control cards and many connections. The Universal Detector Board (Late 1992) replaced twelve individual detectors. The Digital Display Board (Early 1993) eliminated a cumbersome gang switch and seven meters. The Inverter Phase Control Board and the Inverter Gate Driver Board (Late 1994) replaces fourteen circuit boards. Each of these changes has been carefully engineered to be phased into the XC, providing compatibility with older XC models. More than thirty circuits boards and assemblies were eliminated with the resulting elimination of hundreds of wires, each a potential point of failure. There were other changes, such as new redundant 120 volt DC power supplies that provide the power to open circuit breakers in an emergency. 

The PLC was changed to allow more functions in single module systems. Because of its high speed serial communications capability, the new PLC (Early 1993) in multiple module systems has eliminated one hundred wires per module. For added protection, the communications link is redundant. The evolution of the Series XC is an example of the continuing efforts that PS&C makes to provide the best possible product to meet its customers’ needs.
