The actual technical content of medical equipment is low.

1, in terms of reliability and stability, the power frequency machine is stronger than the high frequency machine; 2. In terms of environmental adaptability, high-frequency machines are better than power frequency machines; 3. As far as the load requirement of zero ground voltage is concerned, the power frequency machine is stronger than the high frequency machine. 4. Structurally, the difference between power frequency UPS and high frequency UPS is mainly manifested in the isolation transformer. The use of isolation transformer in power frequency machine greatly improves the reliability of UPS. Therefore, in terms of comprehensive performance, power frequency machines and high frequency machines have their own advantages and disadvantages.

If the reliability and stability of large-scale CT and MRI nuclear magnetic resonance imaging equipment need to be put in the first place, then the high-power industrial frequency UPS of Jingyuan Technology should be the first choice; If it is a computer, printer and other workstations with CT and MRI vibrations or general office applications, you can consider using a lower-cost ordinary high-frequency machine UPS；; If it is color ultrasound, biochemical instrument, blood ball instrument, operating room equipment, etc. We can use our improved version of the high frequency machine. On the basis of the original series of high-frequency machines of Jingyuan Technology, an AC filter is added, which can effectively eliminate ultrasonic artifacts and avoid wave-like radiation interference on two-dimensional echo images.
