Power conditioning transformers provide isolation, voltage stabilization and sometimes noise reduction for sensitive loads such as medical devices, laboratory instruments, broadcast equipment and critical IT systems. They help filter common mode noise, reduce voltage spikes, and create a clean reference ground. Some designs include ferroresonant or regulating functions that maintain output voltage during input fluctuations. By improving power quality at the point of use, conditioning transformers protect sensitive electronics from disturbances that could cause malfunction, data loss or premature failure.
