Medical technology

In hospitals and other fields of medicine, patients and their speedy recovery are the main concerns. However, even a brief power outage may jeopardize successful diagnosis and treatment and seriously endanger the health of patients. It is therefore hardly surprising when particularly high demands are placed on the reliability of power supplies.
