The article discusses one of the possible solutions to the problem with not very high-quality voltage produced by many household generators.

Many who faced the need to use gas or diesel generators during a power outage probably noticed that some devices do not work from electricity generated by the generator.

We received a letter from our regular reader on our site, here is a quote from this letter: ....... "Household generators are mainly brush-mounted, therefore the quality of the generated electricity, to put it mildly, does not correspond to the powered devices. In particular, computer UPSA, when switching to autonomous power, begins to "swear." Are there any filters that make the sine wave more digestible? "" .......

The most rational, in terms of economy, is the use of a UPS uninterruptible power supply, where the battery is used as the energy source.

Today in the Uninterruptible Power Supply-UPS market, there are 3 main types of devices - on-line, off-line and line-interactive UPS. In this short article we will try to figure out what is the difference between these devices, which one is better, the advantages and disadvantages of each of the devices.

Before we begin to analyze the advantages and disadvantages of the UPS, you must determine the degree and importance of the equipment that will power the UPS. In order to determine which device you need, answer a few questions that will facilitate the further selection of the UPS ...

Description of the scheme and principle of operation of a simple emergency lamp based on an energy-saving lamp.

There are situations when during a power outage it is necessary that some area remains lit. For example, it can be a corridor, utility room, or just a workplace. In this situation, an emergency lamp made on the basis of a conventional energy-saving lamp with a power of not more than 9 - 11 watts will greatly help.

When the mains voltage is normal, the lamp works directly from the mains. In the event of a power failure, the lamp switches to battery power. In normal operation, the battery is recharged from the network, thereby maintaining the constant performance of the lamp ...

Modern switches, sockets and dimmers are not only very multifunctional, but also have a diverse design, so everyone can choose the right wiring accessories for their apartment.

In the modern interior, everything matters: the color scheme, the furniture, and some decorative objects. And even properly selected sockets and switches will help give the room a complete look. In addition, wiring accessories are sold today that are not only beautiful in appearance, but also capable of making the life of a modern person more comfortable and safe ...

The article describes a simple and reliable control circuit for an electric pump. Despite the extreme simplicity of the circuit, the device can operate in two modes: water lifting and drainage.

At the cottage or in the farm without water it is simply impossible to do. As a rule, there is no centralized water supply in such remote places, so there are not so many ways to extract water. This is a well, well or open water.If there is electricity in the summer cottage, then the problem of water supply is best solved with the help of an electric pump.

In this case, the pump can operate either in the mode of filling the tank, or in the drainage mode - pumping water from the tank, well or well. In the first case, overflow is possible over the edge of the tank, and in the second case, the pump runs dry ...

The problem with electricity in our homes has become, unfortunately, already commonplace. They can turn off electricity quite unexpectedly, without any warning. And imagine such a situation ... Winter. On the street, frost is under - 20, you go home, the snow crunches under your feet ... Come home, and there ... it's dark, the house is cool, uncomfortable ...

In this short article, we will try to figure out how to avoid situations, so as not to be left without heat, so that your boiler functions at five plus.

If you are the lucky owners of a private house, to ensure uninterrupted power to the heating system, you can between the UPS on batteries and the gas or diesel generator. You decide. Consider the advantages and disadvantages of these alternative sources of electrical energy for autonomous power supply at home.Let's start with Uninterruptible Power Supply (UPS) ...

The article gives a brief description of the properties and methods of using activated water. The description of the device of two devices for its preparation is given.

Activated water is obtained by electrolysis of ordinary tap water. From the point of view of chemistry, living water has alkaline properties that have a healing effect, and dead water has acidic properties, so it has disinfecting properties. Passing through ordinary water, an electric current changes its internal structure and contributes to the erasure of harmful environmental information.

After treatment with electricity, water is divided into two fractions that have healing properties. In the treatment of the disease, live and dead water are taken in various combinations ...

An article on how to replace a mechanical temperature regulator of an oil heating radiator.

Quite often in everyday life you have to use oil radiators for heating. The heating temperature for such radiators is set using an electromechanical regulator, the basis of which is a bimetallic plate - it controls the operation of the mechanical contact.

When such a regulator becomes unusable, it cannot be repaired in almost a hundred percent of cases. It becomes impossible to use a radiator without a temperature controller: either you need to manually turn it on periodically - turn it off, or sit and wait for a fire to happen. The semiconductor temperature controller described in this article will help get rid of this situation ...
