Is it better to buy a voltage regulator or UPS if the computer restarts due to low voltage?

First of all, determine how low the voltage of your home is, first, the voltage is very low but very stable, and second, the voltage is high and low and unstable.

The above two conditions can be seen through **incandescent lamps.

If it is the first case, then push the voltage regulator, it is best to use Delixi's automatic voltage regulator, the internal servo motor, bad transformer, voltage continuous automatic adjustable, regardless of high and low, no need to care, but ** may be biased.

If it is the second case, it is recommended to use UPS, but it is necessary to use *** a little, because a good UPS power supply can not only supply stable power to the computer when the power is suddenly cut off, but also can be transferred to the backup power supply when the voltage is too high or too low, and the self-protection function is also very complete, and the study of mains power and backup power switching will not interrupt the power supply of the computer, and it is difficult to say that the poor quality or defective products are not good, because for the second case, the voltage is high and low, The relay inside the UPS will keep switching, and the damage rate is very high, let alone defective or fake.

Or use ** type UPS (it is recommended to use the four-way UPS or Shante UPS about 1000W) It can stabilize the voltage and backup power It is best to add a 1000W (watt) voltage regulator before UPS.

It's good to buy a voltage regulator, which can maintain the output voltage in the range of 220 5%, so that your computer can work properly. The role of UPS is completely different, the lower price of UPS does not have the role of voltage stabilization, it changes with the change of input voltage, the input voltage is low, the input voltage is high, UPS only plays a sudden power failure, so that the computer is temporarily powered off, so as to play a role in saving files in time without loss.

Buy a low-power regulator.

100-200 will do.

First of all, determine how low the voltage of your home is, first, the voltage is very low but very stable, and second, the voltage.

High and low. Unstable, the above two conditions can be seen through the **incandescent lamp, if it is the first case, then push it to use.

Voltage regulators, preferably used.

Delixi's full.

Automatic voltage regulator.

Adopted in-house. Servo motor.

Bad transformer, voltage continuous automatic adjustability, no matter high or low, no need to take care of, but ** may be a little off.

If it is the second case, it is recommended to use UPS, but it is necessary to use *** a little, because of a good UPS power supply.

Not only can it supply stable power to the computer when the power is suddenly cut off, but also can be transferred to the backup power supply when the voltage is too high or too low, and the self-protection function is also very complete, and the training of mains power and backup power switching will not interrupt the power supply of the computer, poor quality or.

It is difficult to say about the defective product, because for the second case, the voltage is high and low, and the relay inside the UPS will keep switching, and the damage rate is very high, and the defective or fake one cannot be said.

Voltage regulators are used to stabilize voltage.

UPS is also called uninterruptible power supply.

It is possible to continue to supply power to the computer after a power outage.

A device that allows the computer to continue to be used.

UPS generally supplies about 500 for half an hour.

Used by our company.

With 2 servers you can take 4 hours.

That's about 4000.

UPS is also called uninterruptible power supply. But now a lot of UPS still has stabilizers... In other words, it is a dual-purpose machine... Ask when you buy... Is it with voltage stabilization or not with voltage stabilization... And how long can it last...

In the case of voltage regulators, there is only voltage regulation... The power goes out and the power goes out...

UPS is a type of uninterruptible power supply.

The main features are:

for electrical equipment.

It is provided in the event of a power failure.

Emergency power supply, voltage regulator.

is used to. Filter out the voltage instability in the case, two things.

The use is not the same, ups

Generally in the connection in.

Computer. and the power supply between the device, in the event of a power outage.

Power your computer.

There are two ways to supply power, one is to connect at the moment when the external power is disconnected.

Power supply, in general. Use. Diesel fuel.

Gasoline generators, another. Be. Battery.

Storage. I run it with the electricity of the battery while there is a power outage.

Directly with the power supply.

If the individual uses the feeling.

It's useless.

Voltage regulators. Loud noise, right now.

There are basically no power outages.

1. At night, the load is at the peak of the day, so the voltage is very low, and the computer often shuts down or restarts automatically, which will lead to the loss of files and paralyze the system, and in more serious cases, it will burn the power supply or motherboard. In this case, you must install voltage regulator equipment, and the voltage regulator and UPS you mentioned can solve these problems.

2. The working principle of the voltage regulator is to preset the output voltage. When the output voltage changes, the sampling circuit obtains a sample and compares it with the reference circuit to judge the change of the output voltage, and judges the amount of change, thereby controlling the work of the adjustment circuit, and prompting the adjustment circuit to adjust the output voltage to change to low or high until the output reaches the preset voltage.

UPS is also called AC uninterruptible power supply, which can ensure that the computer system continues to work for a period of time after a power outage so that users can save the disk urgently, so that you will not affect your work or lose data due to power failure. It mainly plays two roles: one is emergency use, to prevent sudden power failure and affect normal work, causing damage to the computer; The second is to eliminate "power pollution" such as power surges, instantaneous high voltage, instantaneous low voltage, wire noise and frequency excursion on the mains, improve power quality, and provide high-quality power supply for computer systems.

In principle, UPS is a power protection device containing energy storage devices, with inverters as the main components, and stable voltage and frequency output. It is mainly composed of rectifier, battery, inverter and static switch.

Third, fourth, the regulated power supply, mainly to stabilize the voltage. It cannot be charged. That is, when the power is out, the voltage regulator will also be powered off immediately, which can lead to the data cannot be saved in time and the computer fails. **Cheaper than UPS.

UPS is mainly a function of charging and storing electricity. That is, when there is a power outage, the UPS can use its own stored electricity to power the computer. But the time is shorter, about 30 minutes, so that users can save important information in time.

**A little more expensive than a regulated power supply. According to your actual situation, it is recommended that you configure a household UPS power supply, which is very simple, has a voltage stabilizing effect and continues to invert power supply to 1 hour after power failure, which is very easy to use. ** Not too high less than 300, can solve all your concerns.

It is highly recommended to purchase Shanton uninterruptible regulated power supply.

Of course, it's UPS, at least it has protection when the power goes out and when the voltage is too low, and it won't directly make the computer die with a black screen.

1. UPS

Able to continue to use the computer (about 10 minutes) in the event of a mains power outage, and save data;

However, repair and maintenance costs are expensive;

2. Regulated power supply.

It can ensure the safety of electrical appliances on the occasions when the mains voltage changes greatly, and the general amplitude is +10 20, that is, when the mains voltage changes between 180 240V, it can basically meet the needs of electrical appliances;

The disadvantage is that once the power is cut off, the work will stop immediately, and the need to continue the power supply cannot be guaranteed;

3. UPS with voltage stabilization function

Synthesized the first. The functions of the first and second items are more practical, but the purchase and maintenance are expensive;

From this point of view, if the landlord has frequent power outages and large voltage fluctuations, then UPS with voltage stabilization function should be selected;

If it is only a large voltage fluctuation, it is better to buy a high-power wide-range host power supply for two reasons:

1. The wide (high-power) host power supply is much lower than the general regulated power supply, and the cost performance is very high;

2. The wide host power supply belongs to the special power supply for the computer, and its performance is much higher than that of the ordinary regulated power supply, and the applicable voltage range is generally 150 260V, which can fully meet the basic needs of the computer in terms of voltage.

A single voltage regulator that simply stabilizes the voltage. UPS is a stabilizer with power storage function, and there is still 10 minutes to complete the unfinished work during the power outage. However, there can only be two hosts for one UPS at most, and it depends on how you choose.

This is the case if you are just moving to an apartment.

I suggest you ask people in the same apartment if this is the case.

It's also possible that the power supply of your computer's host computer is not working.

If it is true that the voltage is unstable, use a voltage regulator.

If your apartment has frequent power outages and you don't want to do the work you just did in vain, then use UPS

I think it's better to buy a UPS to use, and it costs a lot of money, with voltage stabilization and surge prevention, and there can be a certain delay.

Buy a 2000-watt voltage regulator, the computer won't jump at all, and you can pull an outlet out by yourself, and you can also connect an electric fan. **About 300, the UPS power supply is useless, it is recommended that you do not buy it.

Install a voltage regulator, better, from your own experience, and the voltage regulator is cheaper.

The general stable voltage of the computer is about 170V-240V, and the computer will restart if the mains power is lower than 170V. It is estimated that the mains power in your application environment will fluctuate frequently, that is, the voltage is unstable, such as from 200V to 160V suddenly, and from 160V to 200V (it may be that there are often high-power devices started nearby, or the mains power may be unstable), in this case, the computer will restart. The function of the voltage regulator is to stabilize the voltage at a certain value, such as 220V, that is, even if the mains power is 170V or 240V, he will adjust the voltage to 220V.

But the voltage regulator has a response time when regulating the voltage, for example, the mains power suddenly drops from 200V to 160V, which is the voltage regulator has an action time, if the action time is too long, your computer will restart. (In my application process, it is basically too long to act, and the computer restarts).

It is recommended that you install UPS between the voltage regulator and the computer, I use it like this, it is quite stable!
