To be. Because in the modern medical system a variety of CT machine, DR, X-ray machine, nuclear magnetic *** vibration of the use. Unquestionably, these devices have a critical role in determining a person's condition, but if the power supply is not properly configured, it is easy to make the CT machine, X-ray machine resolution can not reach a good effect, so the diagnosis to the doctor to bring trouble, but also may be misleading or delayed as a result. Coupled with these medical equipment itself using the characteristics of the power supply, one of the lesion exposure requirements of the regulated power supply output current, voltage drop is small, this moment is not regulated; Secondly, the CT machine itself electrical rectifier circuits, so it is easy to generate harmonics, and the existence of such harmonics, naturally affects the regulated power supply action control incorrectly, so in the hospital premises, the medical special regulated power supply is indispensable.
