Carbon thermostat UNIMAT-a new system for the manufacture of underfloor heating, space heating. It has a unique adaptability property and saves energy.

One of the leading companies in South Korea - GT3 has developed and launched the production of a new system for underfloor heating. This carbon rod based system is called Unimat. Another name for this system is “thermomat”.

Using the Unimat heating system, it is possible to create heating in a room of any size and shape due to the fact that the Unimat heating system is based on the principles of infrared radiation.

Structurally, UNIMAT thermomat consists of carbon-fiber rods connected in parallel and is available in rolls up to 30 m long. The rods are designed with a protective coating that protects them from aggressive substances and makes the entire system electrically safe ...

An article on the use of a device that allows you to competently distribute the power supplied by electric networks.

The end of the nineties. All free capacities in distribution networks are almost selected. The prices for obtaining permission to connect capacity are galloping at an awful rate. But in order to give, the population needs power, distribution networks need to reconstruct and build a huge number of networks and distribution substations.

Financing for the modernization program is practically not allocated. The consumer has to shoulder the problems of distribution networks. According to the technical specifications issued by the same networks, reconstruct or build high-voltage lines in order to bring the point of connection of their capacities closer to the place of their own construction. To buy equipment or finance the reconstruction of distribution substations. And all this in order to get at home or a cottage not 3 kW, but at least 10 kW. So, we will talk about this category of consumers. I will give an interesting example of the relationship of this category of consumers ...

One of the main drawbacks of squirrel-cage induction motors is their high inrush currents. And if theoretically the methods for reducing them have been well developed for quite some time, then almost all of these developments (using starting resistors and reactors, switching from star to triangle, using thyristor voltage regulators, etc.) were used very rarely.

Everything has changed dramatically in our time, because Thanks to the progress of power electronics and microprocessor technology, compact, convenient and efficient soft-start devices for electric motors (soft starters) have appeared on the market.

Soft starters of induction motors are devices that significantly increase the life of electric motors and actuators operating on the shaft of this motor ...

So far, electric cars are not very relevant, but the future lies with them. After all, they use an inexhaustible resource and are absolutely environmentally friendly and cheap.

When pronouncing the word - an electric car, it makes us smile and only a car from a science fiction film comes to mind. Although in the world, they are actively inventing and are already driving them.

Russia has long been accustomed to driving large and powerful SUVs, especially on such off-road conditions. Everything changes in the world, the global financial crisis shows instability and sharp jumps in oil prices. They make us look further into the future ...

Description of the purpose, principle of operation of infrared motion sensors. How to choose a motion sensor to fit your needs.

Today, the issues of applying energy-saving technologies in everyday life are becoming increasingly relevant. The cost of electricity consumed can be significantly reduced by using motion sensors in everyday life (“PIR” - from English - “passive infrared” - “passive infrared”).

Infrared motion sensors designed to close the power circuit in the event of the appearance (movement) of a person (car, etc.) in a controlled area. Depending on the version, the sensors can be used both indoors and outdoors. Household motion sensors use in their work the principle of constant monitoring of infrared radiation in the tracking zone. When an object appears, of sufficient mass and with a temperature exceeding the surrounding by five degrees Celsius, the overall picture of the thermal field changes ...

The purpose of the kit is "Starry Sky". Description, features.

The luminous starry sky is intended for decorative illumination of ceilings, POS materials, the creation of light-dynamic shows and all kinds of decorative elements.

"Starry sky" consists of LED dots that are sequentially soldered into a loop, which go in a loop with ballast resistors.

You can control this light with the help of controllers, to which you can connect any number of channels, you can control the dynamic light and embedded scenarios in these controllers, special infrared remote controls are often used with such controllers ...

A brief overview of equipment technologies and prices of data transmission devices over 220/380 V. networks

Due to the rapid development of home automation and the cost of laying additional communication lines, data transmission between various devices on existing 220-380V lines is of great interest. "From the outlet to the outlet."

The control and controlled device or devices are connected by standard network wires to a home electrical outlet and receive power and control signals from it.

Thus, local networks between computers, security and fire alarm networks, Smart Home systems and the like can be built. The complexity of organizing such networks lies in the fact that this was not originally envisaged, there are no uniform standards, the networks are very noisy, and their parameters change greatly when the load changes.

The economic calculation of the payback and economic efficiency of energy-saving (fluorescent) lamps.

In Russia, every year more and more is not enough electricity. It is becoming increasingly difficult to obtain permission to connect industrial facilities and private households. According to the forecasts of power engineers, the doubling of electricity generation will occur no earlier than in 15 years. Therefore, electricity prices are constantly growing and will strive to reach the average European - 9 rubles / kWh.

However, there is a fairly simple way to achieve energy savings and reduce the cost of its purchase ...
