Understand what is the difference between UPS s 3 in and 3 out

At present, the first-class UPS input is made of PFC high-frequency rectification technology, and the input voltage can be started with full load at about 175 280. Taking Delta's N-series UPS as an example, the UPS is in the range of 80V and 165V, and the load capacity gradually increases from 50 to 100% with the voltage. It can work with full load in the range of 166V and 280V.

4 computers, if it is not a CRT monitor, or an ash configuration such as a dual graphics card, there should be no problem with 2kva UPS, it is recommended that the four computers be turned on, the order can be staggered, and they should be turned on one by one.

Buy a Shante, ** are with voltage stabilization function, 2K standard machine if you buy, that is, about 2000, can bring a delay of about 10 minutes, if it is purely voltage stabilization, you can buy a stabilized power supply, a few hundred yuan will be done.

2K machines will basically have a voltage stabilization function. With 4 computers with Shante's estimation can not afford to bring, UPS's load rate is best not to exceed 80%, otherwise it will be "very tired", which will affect his voltage stabilization inverter function, Shante's 2K power is about 1400W, you can calculate your load, in the case of four at the same time, the delay of the standard machine will not exceed 10 minutes, of course, this time to save the file is enough. Shante currently has a lot in the market, the circulation is very wide, because the ** is relatively low, the quality is OK, but it is recommended that if the conditions are good, it will be better to buy a better brand, with 2k machine power is best above, if you need a long delay time, you can be equipped with a long machine plus battery pack.

Shante 2k standard does not exceed 3000 (the American Shante is within 2500 rockery), and Emerson's 2k mark is less than 5000.

About UPS's several in and out refers to his input and output, probably divided into several kinds of three in and three out, single in and single out, three in and out of the single, and now there is a single in and three out, here three and single live to refer to the phase system, three refers to three phases, single refers to single phase (three phase is what we often say 380V electricity, single phase is our home and office commonly used 220V electricity); As you said, 3 in and 3 out is commonly said that the input is a 380V power supply, and the output is also 380V electricity to the equipment to be connected, and the 3 in and single out is that the input end of UPS is 380V, and the output end is 220V.

As for the advantages, there is nothing, but the 3 in and 3 out are relatively stable, this mainly depends on your own needs, what kind of power you want UPS to provide you (380 220).

That's all for now, if there's anything else, we can ** each other.

The difference between UPS's 3 in and 3 out and 3 in and out is:

1. UPS means "uninterruptible power supply", which is the abbreviation of "uninterruptible power supply" in English, which can ensure that the computer system continues to work for a period of time after the power outage so that the user can save the disk urgently, so as not to affect the work or lose data due to the power failure.

2. When the UPS uninterruptible power supply is designed, three input and output modes are designed according to the required voltage of the equipment: single input and single output, three input and single output, and three input and three output. UPS uninterruptible power supply single input and single output means that both the input and output are 220V.

The input is 380V and the output is 220V, and the input and output are 380V.

3. Three-in and three-out uninterruptible power supply and three-in single-out uninterruptible power supply have their own advantages, 3 in and 3 out are relatively stable, three in and three out can output 220V or 380V voltage, but three-in and single-out UPS power supply can only output 220V.

The input 10 square line is about the same, and the output 16 square line is about the same.

Regardless of any electrical equipment, to calculate the wire diameter of the power supply line, you first need to know the maximum power (or maximum working current) of the electrical equipment, followed by the length of the power supply distance, and finally the maximum and minimum working voltage, so as to calculate the wire diameter of the power line.

UPS is 20kV, the correct description should be 20kVA, KV is the voltage, KVA is the capacity of UPS. If it is a single-phase input UPS, the maximum current is about 100A, it is recommended to choose a 35 square multi-core copper wire;

If it is a 3-phase input three-phase input UPS, the maximum working current of each phase is about 35A, it is recommended to choose a 16 square multi-core copper wire, and if it is a three-phase input, single-phase output UPS, it is recommended to choose a 16 square multi-core copper wire, and two 35 square bypass input power cables need to be installed.

You are talking about 20kva, it should be a three-phase input, you need 6 square meters, if the distance is long, consider the loss of 10 square is more safe.

I'll pass you a copy of the 20k instruction manual, and I'll pass it on Shante's as a reference.

The input 10 square line is about the same, and the output 16 square line is about the same.

Subject to the actual manual requirements.

If you don't enter, estimate as 20 * 4.

The output is estimated on a 20 * 4 basis.

For details, please consult the engineering department of Epno.

It's clear at a glance.,Which position corresponds.。

It's three binding posts covered by a white iron plate, right?

Isn't it marked? That one is connected to the output, L is connected to the live wire, and N is connected to the neutral wire, as if the middle one is grounded.

That must not be connected, the UPS power supply line can share the zero row, but after the inverter voltage, the zero line can not be connected to the zero line of the incoming line, and the accident causes losses! So you have to separate the zero rows, which can't be saved

OK. All neutrals can be connected to the same zero row.

It is best not to pick up a zero card, and it is best to do 1 zero card alone when UPS qualifys.

Hehe! One price and one goods, you have to buy good in this case.

This can also be achieved by UPS, but not by voltage regulators! You have to buy a UPS with good voltage stabilization, otherwise the UPS itself may be damaged!

Hello landlord! Do you want to ask if the IEC interface behind the host is not the national standard interface, and the equipment you load can't be connected correctly! There are 2 solutions to first encounter this kind.

1. Buy PDU and take the output directly from the UPS output IEC port. In connecting all the equipment to the PDU 2, change the national standard wiring plug-in board, change the national standard wiring plug-in board to IEC interface, and connect to the IEC interface of the host backup, the equipment is connected to the plug-in board to get power. I hope the appeal will be helpful to the landlord, thank you!

If you have any questions, please feel free to contact me.

Shante C6K machine, DC starting voltage 192V, you only need to connect 16 batteries in series, and then measure the voltage at about 192V, connect the positive and negative wires of the battery to the DC terminal of the UPS machine, and you can do it. Remember not to short circuit the wiring, do not connect the negative pole, and remember to disconnect the empty switch on the battery cabinet when wiring.

The voltage of three in and three out is 380, and the voltage of 220 can be changed to 220 for single and single out, and 380 can be changed to 220, but some equipment requires a voltage of 380.

You're a talent too! If it is a general commercial UPS: below 10kva is basically a single (220V 220V); More than 30kva are all three three (380v 380v).

It can be seen through the wiring row behind the UPS, and it is also explained in the manual.

Classified according to whether the battery is connected: long machine - external battery pack; Standard machine - built-in battery, not external.
