UPS Recommendations

Grounding for such devices is required. If this is not done, then the internal voltage regulator simply will not work. In addition, in the event of a breakdown, the manufacturer may consider the lack of grounding as a non-compliance with the operating conditions. This will cause the warranty repair to be denied.

A nice addition to the standard UPS configuration are USB connectors designed to charge mobile devices. It is convenient if they are located on the front panel, and not behind

To connect not too powerful printers, you can use the connector, which is usually found on the rear panel. It is not recommended to disconnect the UPS from the mains, whether there is power or not. After the restoration of power supply, the procedure for charging the built-in battery will immediately begin.

Choose a place for the UPS in such a way that the device does not interfere with the use of other devices. Usually placed on the floor

UPS components become hot during operation. This attracts insects that get stuffed into the body, causing breakage. Therefore, it is recommended to protect the room in which the device is installed from insects, and also to clean it regularly.

Do not install UPS in the bedroom. During operation, the device emits a noise of about 45 dB. This is not too much for the daytime, but it will prevent you from falling asleep at night.

We have an article on our website about how to choose an uninterruptible for a gas boiler, we recommend that you read it.

Backup Power Supply Modifications

Uninterruptible power supplies can be classified according to different criteria: type of battery, installation method (floor or wall), purpose, safety, etc. The generally accepted division into types is carried out according to the principle of operation. UPSs are divided into three main classes:

• linear or off-line (Off-Line);
• linear-interactive (Line-Interactive);
• double conversion or on-line (On-Line).

Each modification of backup power sources has its advantages and disadvantages, which determine the operating conditions for each type of equipment.

Linear

Linear UPSs belong to the budget series of devices of this type. Their design does not include a stabilizer or autotransformer.They operate in a given voltage range from 170 to 270V. When power surges beyond the specified interval, the power is switched from the network to the battery.

Due to the lack of a stabilization unit, the output voltage has the same unstable sinusoid as the input voltage. This leads to malfunctions in the electrical equipment of the gas boiler. The power transfer time is 15ms in one direction or the other. When choosing off-line uninterruptible power supplies, it should be borne in mind that intense voltage drops in domestic electrical networks, especially in winter, have a negative effect on the device. This fact reduces the life of the UPS by several times.

Advice. Off-Line backup power sources are not designed to work in conjunction with generator sets running on diesel or gasoline fuel.

Line Interactive

The main difference between linear-interactive UPS and linear UPS is the presence of a voltage stabilizer or automatic voltage in the equipment design. These modules help to equalize the voltage sinusoid to optimal parameters. This ensures the operation of the gas boiler in normal mode and extends the service life. The extreme voltage limits at which the backup power supply operates in idle mode are 170 and 270 V. Switching power from the battery and back is carried out automatically.

From practical experience, experts note the incorrect operation of some models of the device with gasoline or diesel-type generators. The design of the unit provides for the connection of external batteries.

double conversion

Uninterruptible power supplies of the On-Line type, unlike the other two types, have a more complex circuit diagram of operation and connection. The design of the device provides an inverter for double conversion of electric current.

The principle of operation of the device is as follows. The input AC voltage 220 V from the electric line is inverted into a constant 12 V or 24 V, depending on the modification of the gas equipment. As a result, the sinusoidal signal is rectified to a stable value, which is a direct current.

At the second stage, the stabilized DC voltage is converted back to AC voltage 220 V with a stable frequency of 50 Hz by the inverter. Double conversion UPS operate in the range of 110 - 300 V. On-line operation of the device ensures stable operation of the gas boiler at low or high voltage, without switching power to the battery. This helps extend the life of the battery before it needs to be replaced.

According to the type of installation, devices are available in two types: wall and floor

Battery

When choosing a UPS, you should pay attention to the capacity of the battery. The operating time of the gas boiler from the backup power source depends on its parameters.

In the event of a power outage for a long time, the battery that the UPS is equipped with must ensure uninterrupted operation of the boiler for up to 10 hours. If it is possible to connect an external battery, make sure that the batteries are of the same capacity.

How to determine the required power?

When choosing an uninterruptible power supply for home use, personal computer owners should pay close attention to a very important parameter - power. In order not to make a mistake and purchase a really high-quality and reliable UPS, they should make accurate calculations

The load (maximum) should not exceed 70% of the output power of the UPS. Such characteristics should be indicated by manufacturers in the accompanying documentation. But, each buyer is able to carry out all the calculations on his own, without the involvement of third-party specialists. To do this, it is enough to make the following calculations:

• the processor consumes up to 65W;
• video card up to 170W;
• motherboard up to 40W;
• DVD drive up to 20W;
• HDD up to 40W;
• other equipment up to 30W;
• possible losses up to 20%.

As a result, a personal computer will consume up to 365W, without taking into account possible losses. If you add them, then the total amount will increase to 438W. Therefore, the owner of a personal computer should purchase an uninterruptible power supply, the power of which ranges from 500-620W.

Normal UPS run time is 5-8 minutes

Rating of the best UPS models for a computer

Uninterruptible power supplies are a necessary device for PCs and household appliances, especially if your place of residence is characterized by frequent power outages or power surges. When choosing a UPS, you should focus on:

• work stability;
• duration and ease of use;
• power;
• noiselessness;
• dimensions and weight of the equipment;
• value for money;
• manufacturer.

Based on these parameters, a rating of uninterruptible power supplies for personal computers was compiled, which will help in choosing this equipment.
