Properly Sizing UPSs for Diagnostic Imaging Systems

摘要

Due to the dynamic power characteristics of diagnostic imaging systems like Magnetic Resonance Imaging (MRI), Computerized Tomography (CT), and X-ray imaging additional demands will be made on Uninterruptible Power Supplies (UPS) products that support them. When UPS products are used to protect diagnostic imaging systems they have to be selected and validated to assure that they will handle the unique power characteristic requirements of these systems. Not all UPS products are capable of supporting these types of load requirements and just making them bigger does not mean or guarantee that they will work. The UPS specifications, selection, validation, and testing with these diagnostic imaging systems will be discussed as well as possible problems that will be encountered and their solutions. Case studies of UPS products that do not support diagnostic imaging systems will also be discussed.
