Reported risk: There is an increase in the failure rate of certain Anode Drive Units (ADU5) used in these products. Early life failure of the ADUs only occurs when the hospital mains provide 480V to the system. This current voltage may lead to saturation and overheating of the coils that protect the IGBTs (insulated-gate bipolar transistor) of the ADU. The overheating may also generate a peculiar burning smell that may be noticed. In some instances this burning smell may be noticed before the ADU fails. When the ADU fails the X-ray performance of the system is reduced to Emergency Fluoroscopy. Exposure will not be possible and image quality is reduced.
