When should I consider replacing my UPS or the electronics inside my UPS?

Depending on environmental conditions UPS electronics may begin to show internal component wear after about 10 years. While internal components could be replaced individually, best practices dictate that the assembly be replaced. Even in the absence of an electronics failure, proactive replacement will enhance system reliability and peace of mind. Eaton technicians use a variety of tools and techniques to evaluate the status of UPS electronics and can use the data gathered during preventive maintenance visits or via the PredictPulse capability to recommend proactive UPS or UPS electronics replacement. Running a UPS in power efficiency modes like Eaton’s Energy Saver System (ESS) will lengthen power component life. When the UPS is in ready-to-serve mode, the modules are subjected to less heat stress.
