Piezoelectric Transformers Piezoelectric Transformers .. Handling Precautions Piezoelectric Transformers may fail in either short-circuit or open-circuit mode. When subjected to severe electrical/environmental conditions and/or mechanical stresses beyond the specified ratings, overheating and/or damage may result. Failure to follow the "SAFETY PRECAUTIONS" or "Application NOTES" may result in product malfunction. If you have questions regarding the "SAFETY PRECAUTIONS" or Application Notes, please contact our engineering section or factory. Safety Precautions 1 When Piezoelectric Transformers are operated beyond their specified electrical and enviromental ratings, they may overheat or burn out. For safety, it is remended that you establish a protective circuit for over heating. The assembled ponents and materials near the transformer should be of a flame-retardant type material (UL94V-0 orequivalant) and of a high heat resistance. 2 Piezoelectric transformers, should be covered with protective cases to prevent accidental contact and electric shock. "Warning - High Voltage" should be labeled on...
