Do not understand the ups on the 3 into the 3 out of this parameter in the end what advantage!
As for the advantage is nothing, but 3 into 3 out of the relatively stable point, this is mainly to see your own needs, you want UPS to provide you with what kind of power (380/220).
On the UPS into a few points out of his input and output, probably divided into three kinds of three into three, single into a single, three into a single, and now there is a single into three, here Three and single live is to refer to the phase, the three refers to the three-phase, single refers to the single phase (three-phase is that we often say 380V of electricity, single-phase is our home and office commonly used 220V) ; As you said 3 into the 3 out of the popular say that the input is used 380V power supply, the output is 380V power to the equipment to be connected, 3 into the single is the UPS input is 380V, the output is 220V.
Ups 3 into 3 out with 3 into the single out of the difference is:
1, UPS means "uninterruptible power supply", is the English "Uninterruptible Power Supply" abbreviation, it can protect the computer system after the power failure to continue working for some time so that users can save the emergency, not due to power failure and work or loss data.
2, UPS uninterruptible power supply in the design of the time, according to the equipment requirements of the voltage design of three input and output modes: single into a single, three into a single, three into three. UPS uninterruptible power supply single input refers to the input and output are 220V. Three into a single output is 380V output is 220V, three into three is the input and output are 380V.
3, three into three uninterruptible power supply and three into a single uninterruptible power supply has its own advantages, 3 into 3 out of the relatively stable, three into three can output 220V or 380V voltage, but three into a single UPS power supply can only output 220V.
