Uninterruptible power supply equipment power common sense

Online UPS "online" meaning includes what, what are the basic features?

The meaning includes: ① zero conversion time; 

                                   ② low output voltage regulation rate; 

                                   ③ can filter the input power surge, clutter and other features.

The frequency stability of the UPS output voltage refers to what is the difference between the various types of UPS?

UPS output voltage frequency stability refers to the size of the UPS output voltage and frequency change at no load and full load. Especially in the input voltage range of maximum and minimum value changes can still have a good output voltage frequency stability. For this requirement, the online UPS is far better than the backup and online interactive type, while the online interactive UPS is comparable to the backup type.
