The problem of frequent burnout of lamps is quite common in our time. Lamp manufacturers claim lamp operation for several thousand hours. But in fact, the lamp can burn out without having worked even a few hundred hours, or even less. If you often have to change the lamps, then you can use a special device that will ensure the continuous operation of any lamp. In this article, we consider one of the most common devices - the lamp protection unit "Granite".

What functions does this device perform? The lamp protection units have a unique system that ensures a smooth start of the lamp. That is, this device protects the lamp from inrush currents when it is turned on, which is the main reason for the burnout of the lamps, regardless of their type. In addition, the protection units "Granite" provide reliable protection for lighting equipment ...

A few recommendations regarding the choice of power supply for powering LED strips. A brief overview of several of the most popular power supplies for powering LED lighting.

Lighting equipment in our time has a large assortment. Currently, the buyer is presented with many modern developments in the field of lighting equipment, in particular LED lighting (LED strips, lamps, lamps). If you decide to use LED strips in the design of your apartment, then you should know some features.

One of the features is that you cannot directly connect an LED strip to the network, such as a conventional incandescent lamp or housekeeper. This is due to the fact that the operating voltage of the LED strip is much lower than the voltage of the household network, as a rule, this is 12 V ...

Socket blocks are used for good organization and convenient functioning of various workstations equipped with various office equipment for information and electric power networks.

An important role in these matters is played by sliding socket units with various options for the execution of their housing, the aesthetics of placement in the interior of the premises and their types of attachment to furniture.

Today, the Russian market, both simple modular and built-in retractable sockets, is represented by products of such world-famous "brands" as the Spanish company Simon Connect, the German EvoLine, the Russian company Ecoplast. The installation of various outlet blocks, including retractable ones - any of us is able to perform independently. There are many types of modern outlet blocks, both for their installation in racks and cabinets, and wall-mounted ...

When we hear the phrase "track lighting", we most often imagine large, bulky and ugly metal paths cluttering up the room.

Such a purely negative view of track lighting is erroneous, since, at present, manufacturers of this type of lighting equipment produce hundreds of decorative track systems. They allow designers to correctly organize lighting in complex interiors and get both general lighting and additional interior lighting. Thanks to this, track systems are most often a very economical option for lighting rooms.

There are several device options for track lighting systems - on one and two pendants of various shapes, on a monorail, busbar, track lights on separate brackets. One of the new options is the use of special cable systems. We will talk about them in this article ...

Reading about Bill Gates’s mansion worth $ 53 million, equipped with an ultra-modern “smart home” system, you involuntarily grunt: we would have his money - if the house were even “smarter”. And if you think about it, then our home is gradually acquiring elements of intelligence.

It’s rare that anyone controls a TV manually today - there is a remote control that takes care of all the setup tasks. Keychain motorists habitually lock cars. Modern refrigerators with programming operating modes, washing machines with dozens of washing programs - electronics imperceptibly, but surely enters into our everyday life.

And only lighting until recently has been deprived of attention. The emergence of a series of devices that allow you to remotely control the lighting of apartments by transmitting commands over the air, marked the end of the era of archaic keyboard switches ...

When mounting electrical cabinets, sometimes you have to mount rather massive components on the mounting panel that cannot be fastened tightly, because they need to be removed from time to time for various reasons - for replacement, for maintenance, etc., for example, electricity meters (meters ), frequency drives, etc. Usually they are fixed with screws.

For this, it is necessary to provide threaded holes in the mounting panel so that when they are removed, the entire panel in the mounted cabinet must not be removed in order to get the fixing nuts from the back of the panel.

With their small diameters, a panel made of a thin sheet is enough to bulge and cut the M3, M4 thread into them, but for greater bearing capacity with the M5, M6 threads this way you can’t do, because you cannot make such a thread in a thin sheet of a panel. It is necessary to put threaded bushings in these places. At the next trip, the store in the fastener department, I came across threaded rivets ...

Network interference as they arise. Network filter device, the purpose of its elements. Features of network filters.

Alternating current in a household network is sinusoidal. This means that changes in voltage, and, consequently, in current, occur along a sinusoid, that is, along a smooth arc that oscillates symmetrically around the time axis. In one second, the voltage in the outlet changes its value from +310 to -310 volts fifty times. So, in theory, an AC network of 220 volts 50 hertz works.

However, if we look at the voltage waveform in our outlet, we will see that it is far from ideal. What is there a sinusoid !? Continuous peaks, impulses, shape distortions, amplitude changes, throws and jumps - this is what we will see. All this very spoils the picture and is able to disable household appliances ...
