UPS for the computer: types, selection criteria, the rating of the best

Perhaps there is no person who has not faced with instability of the national electricity networks. The voltage falls, rises, if not the electricity disappears. And if the household appliance that does not mean death sentence, the sensitive electronics such as a computer like power surges can permanently damage. To avoid trouble, you need to set your computer to the UPS (uninterruptible power supply).

The need to use UPS for the computer

The uninterruptible power supply has a special battery by which domestic and electrical equipment may be for some time to continue its work after the changes in voltage or in case of emergency power outage. There are devices for different types of technology - PC gas-fired boilers, Electrical equipment sensitive to voltage surges. However, in this review we consider only bespereboynik for computers. UPS (UPS) makes it possible to correctly complete the program of work and turn off the PC during a power failure, as well as to protect all components of the electronic device from the negative effects of sharp discontinuities voltage.

In this article, we consider the most important parameters of the uninterruptible power supply for home to make the right choice and to buy exactly the device you want.

The main types of uninterruptible power sources for computers

Manufacturers offer a variety of types of UPS for home, different weight characteristics:

• on the principle of operation - standby (Back-UPS), line-interactive (Smart-UPS), double-conversion UPS (On-Line);
• the auto-voltage type;
• quality filter network interference;
• capacity of the battery;
• response time device when the voltage is turned off;
• possibility of connection of additional batteries for UPS;
• various additional functions.

Reserve (Back-UPS)

Reserve bespereboynik or off-line has the simple structure and principle of the following steps:

• in the presence of mains voltage electricity is fed through directly to the UPS device and charging the battery simultaneously. Electricity is not regulated, and a noise filter on the most basic level;
• power outages bespereboynik switch your PC on battery power. An inverter that converts the direct current to alternating current established in the most simple devices of this type, and therefore, the waveform does not correspond to a correct sine wave;
• bespereboynik also included in the work for changes of threshold voltage values ​​set by the manufacturer according to the model;
• time on the UPS is 5 ÷ 20 ms, which is pretty much as in some models of such a delay may adversely affect the functioning of the device.

The benefits of off-line models include low cost, quiet operation and high level of efficiency. Among the deficiencies noted the duration of the transition to the offline mode is not sinusoidal output is not enough quality filtering noise and pulses, and the absence of voltage and frequency adjustment during operation of power.

Reasons to buy for the computer line-interactive UPS

This type of UPS users are most popular due to the optimal combination of price and functionality. Its concept is present automatically adjusts the input voltage - AVR. At normal voltage value when running on a network passes through bespereboynik passive filters the incoming signal, while the battery charging occurs.

With an increase or decrease of permissible voltage values ​​UPS computer switches to battery operation. When the UPS battery state of charge 70% and a voltage of 160 V, the device go into standalone mode and at 30% in the charge and voltage will be 150 V by adjusting AVR.

Some line-interactive model based on the output signal bespereboynik practically no different from off-line type devices having a stepped shape sinusoid. Smart-UPS device type puts the computer to battery much faster than the UPS backup.

Advantages of line-interactive bespereboynik is:

• affordable price;
• quiet operation of the device;
• autoregulation voltage;
• fast switching devices from the mains to the battery - the average time is 2 ÷ 8 ms.

The disadvantages can be attributed the lack of frequency adjustment is still insufficient filtering of various noise and harshness voltage regulation, low efficiency in comparison with off-line UPS.

Uninterruptible power double conversion (On-Line)

This type of UPS is a professional, most reliable and expensive device that is ideal for ultra-sensitive equipment. Models of this type operate on the principle of dual converting an input electricity - a first constant current and already after a variable. Consequently, the efficiency of the device is increased to 95%, and noise and interference due to double transform completely disappear.

Since the On-Line UPS devices for private home runs almost constantly, it can instantly if necessary switch the computer from the power supply to the battery as the power runs through a rectifier, battery (in charge) and inverter. Double conversion UPS can also operate in "bypass" mode. This is a spare line running directly from input to output bespereboynik, bypassing the rectifier, battery and inverter. Such a system makes it possible in an emergency (for the device) situations apply voltage to the PC directly.

Pros bespereboynik double conversion is as follows:

• incessant frequency and voltage stabilization;
• effective filtration of all kinds of interference;
• pure sine wave output and instant switching to battery operation.

The disadvantages include:

• high price;
• the lowest efficiency of all types of UPS, but there are exceptions, and so when you buy should read the instructions carefully;
• due to continuous operation of the UPS generates much heat due to which effective cooling is necessary, that means not completely quiet operation of the device unlike other types bespereboynik.

How to choose UPS for the computer on the main characteristics

you need to know the basic characteristics of the device in order to select a good uninterruptible power supply for computers. Among the most important parameters stand out:

• power;
• the battery life;
• software;
• control means;
• types and number of connectors.

Before you select the effective uninterruptible power supply for your appliances need to carefully examine all the technical characteristics of the device in order to acquire the necessary model.

How to choose UPS for the computer device power

To ensure uninterrupted power supply for the house must be considered one of the most important parameters - the maximum capacity of the equipment that can be connected to the UPS. In the event that the maximum value of the connected equipment will be higher maximum power of the UPS, the unit will simply fail. To select bespereboynik ideal for your equipment need to calculate in advance its capacity, what can be done with the help of the following claims.

W_UPS = W_PC (Or the amount of power in all equipment) / 0,6 × 1,4,Where

• 0,6 - load transfer coefficient of the W VA (volt-amps);
• 1,4 - coefficient headroom for UPS.

Runtimes

This characteristic is directly related to the capacity of the battery, which is equipped with UPS. Most of the uninterruptible power supply models can operate in a standalone mode for 4 ÷ 8 minutes. This time is quite enough to make the system failed to correctly close all programs, save the edited documents and turn off the computer.

Some UPS models are able to work out about 15 ÷ 20 minutes after a power failure. However, such devices are of course are more expensive than their other counterparts because of the large capacity batteries. Such bespereboynik especially good if it is connected to several types of household appliances.

Software

Because some bespereboynik should not only be connected to an electrical outlet and the PC, but also be able "Communicate" with the computer's operating system, for return instructions provide the necessary data and monitor the work device. To do this, all models of UPS manufacturers equip special software.

Before you buy a home bespereboynik need to make sure it is compatible with the "OSes" on your computer, and it can be connected through the Internet, USB or COM-ports. If no user on the network power goes, thanks to special software bespereboynik will properly shut down running programs and shut down your PC.

management Tools

In addition to sound alarm which informs the user of the UPS goes offline mode when power outage and LED models are equipped with some advanced manufacturer LCD displays. In these small screens reflected virtually all the information about the work and the state of the uninterruptible power supply. display through a user is able to set a specific mode for your equipment.

The types and number of connectors

Typically, UPS for PCs equipped with sockets, protected both from a power outage on the network, and from power surges. When choosing bespereboynik should take into account the number of both types of connectors, as is likely, you will need at least two sockets protected against power failure in the power supply.

Budget bespereboynik equipped with 1-2 connectors for attaching external devices - system unit and monitor. In the more expensive models, producers set longer socketsAs well as the type of USB connector or an RJ-45.

How to avoid mistakes when selecting a computer for bespereboynik

We have already briefly considered the main characteristics of the uninterruptible power supply. Let's look at some of the parameters of the device, which is necessary to pay attention to when choosing bespereboynik Housing is a power failure.

The choice of power

As already mentioned, the most important parameters of the UPS is its power. However, in order to buy a device that will keep your appliances from the hassles associated with shutdown electricity and voltage fluctuations, one must also know the power and equipment to be connected, in this case, the system unit and monitor.

Determine the monitor power will not be difficult, since it is usually indicated on the device. The situation is worse with the system unit, as the calculation of the weight value is difficult without special instruments. Typically sistemnika capacity is 2-3 times lower than the value specified on the housing pulsed power supply. Therefore, when assembling a PC, as a rule, guided by the maximum power consumption.

Tip! When purchasing desirable to choose the UPS device with the power headroom approximately 20% greater than the total capacity of the equipment being connected.

By connection type

Uninterruptible power supplies also vary according to the input and output connections.

The types of input connections

UPS designed for use at home, office and server, small and medium power up to 2 kVA, characterized by a connector IEC-320 C13, the same as on the PC power supply. Some models of home computers have built-in power cord. Bespereboynik having power 2 ÷ 5 kVA equipped connector IEC-320 C19, which is different from the previous presence contacts, calculated at 16A and form. The UPS output power of 5 kVA used rigid attachment in three phases and "earth".

The types of outlet connection

The low-power uninterruptible power supplies for home use typically use the output jacks Schuko CEE 7 Type F under the plug. In office devices commonly used socket type IEC-320 C13, and UPS for server simultaneously established IEC-320 C13 to IEC-320 C19. One- and multishelf systems are equipped with three-phase connections for a hard connection.

Over a range of input voltages

Before you go to the store to purchase the UPS for your computer, you must evaluate the quality of household power - noise, surges, frequency Total power off, etc. Based on these data, determined by the input voltage range of the working time and working in standalone equipment mode.

Input voltage range defines the allowable values, within which the uninterruptible may deliver power to the connected equipment without involving a stable voltage battery battery. UPS backup type has a small range - about 190 ÷ 260 V, while the inverter and interactive it is much wider. In some models bespereboynik provides the ability to manually adjust the input voltage limits.
