Expanding the list of household appliances with engineering equipment inevitably increases the requirements for the load on the power grid. Along with this, the risk of failure of the device during power surges increases. Therefore, owners of homes with expensive home appliances are advised to purchase equipment that stabilizes the network. Especially for domestic use, compact and easy-to-operate devices are produced that minimize the likelihood of such changes. A traditional solution is an electromechanical stabilizer with basic functionality and a familiar interface.
What is the peculiarity of electromechanical models?
Today's market offers mainly relay and electronic models of stabilizers, which have many of their own advantages. For example, electronic devices demonstrate a combination of high accuracy, reliability and ergonomics, although they are more expensive than their competitors and usually have large sizes. Most often, there is a choice between affordable stabilizer models. Relay or electromechanical - which one is preferable? The first option is characterized by low accuracy of adjustment, noise operation and at the same time the lowest cost. In turn, electromechanical devices are able to provide sufficient accuracy for home use and resistance to overloads. They are also sensitive to temperature fluctuations and lose to their counterparts in stabilization rate.
The pros and cons of electromechanics are determined by the principle of operation. An automatic converter is introduced into the circuit of such models, which is located in the initial winding of the main boost transformer. Direct adjustment is made by manipulating the graphite brush contact associated with the servo drive. Therefore, the electromechanical stabilizer requires more time for the reaction, sometimes it makes noise at high loads, but it allows you to more accurately adjust the network parameters.
Single or two phase?
One of the basic divisions of stabilizing equipment, which will determine the possibilities for its operation. For home use, single-phase devices are more often recommended, since they are designed to service a 220 V. network. It is obvious that most household appliances are powered by the same sources. Three-phase stabilizers operate with a 380 V network and are oriented mainly at operation in production conditions, in construction and industry. But at home they may be needed, albeit not in regular use. For example, to protect against overloading of electric furnaces, welding equipment or powerful pumps. One more thing to consider. The fact is that single-phase electromechanical stabilizers for 220 V can be network (standard models) and trunk. The first devices are habitually connected to the network, and the main ones are introduced into the central electromechanical wiring and thus serve all the devices and equipment that are used at the target facility.
Key Features
The primary characteristic of stabilizers is directly related to their function. This is the value of active power, which in the case of household models can be on average 5-7 kW. Of course, if you want, you can find devices for 9, 22 and more kW. The choice depends on which devices a particular electromechanical stabilizer should work with and in what quantity. The total load of all serviced devices is calculated, the same active power is derived from it. At the same time, experts recommend adding another 20-25% to the calculated indicator for safety reasons.
The next characteristic is the stabilization range. This is the spectrum in which the equipment will be able to control the magnitude of the voltage, ensuring the safety of the devices. In particular, the best electromechanical voltage stabilizers cover the range from 130 to 280 V. Inexpensive budget models work in the corridors of the order of 140-260 V. Such characteristics as accuracy and stabilization speed are also important. In terms of accuracy, such devices can show deviations in the range from 1.5 to 3%, and the reaction rate is small - 5-10 V / s.
Reviews about stabilizers ORTEA Vega
The Italian manufacturer, which is considered one of the leaders in the segment, but does not abandon traditional solutions. In the Vega family of stabilizers, models of various types of power from 2 to 15 kW are presented - this is a line for domestic use and cottages. The owners of these devices note the high quality of constructional performance, which is manifested in the coordinated work of mechanisms with graphite rollers and the durability of the filling. In addition, if a typical electromechanical stabilizer is associated with small delays in response to network fluctuations, then Vega devices instantly respond to voltage changes. At the same time, high accuracy and a wide range of coverage of operating quantities are retained. Some models work with limits from 123 to 314 V. However, for such advantages it is necessary to pay a considerable amount - an average of 20-25 thousand rubles.
RUCELF SDWII-6000-L Reviews
Another good option from the category of electromechanical models of stabilizers. First of all, the device deserves attention due to the convenient mounting system - as users note, it is enough to install it once on the wall and do not return to the installation topic anymore. It does not take up much space, does not overheat and practically does not make noise. As for the working qualities, the electromechanical voltage stabilizer in the SDWII-6000-L modification is highly appreciated for its high speed of adjustment, accuracy and a wide range of options, including the possibility of delayed start and bypass.
Reviews on the model "Resanta ACH-5000/1-EM"
You can not ignore the products of the most popular domestic manufacturer of stabilizers. The model under consideration is also characterized by rather attractive indicators of the accuracy of adjustment and, as practice shows, maintains productivity even in conditions of frequent voltage drops. The only negative is the restrictions on wide voltage ranges. This electromechanical stabilizer is not recommended just for regular drops in large spectra, since the alignment speed of the circuit parameters is only 10 V / sec.
What else to consider in choosing?
If the stabilizer suits the main electrical parameters, then you can go to the ergonomic qualities of the device. This applies, in particular, to the implementation of the interface through which the user interacts with the technology. The modern electromechanical stabilizer is equipped with an information display in many versions. This panel displays all the necessary network parameters, including voltage, load indicator, etc.
It is also worth considering compatibility with the target equipment. Not all devices and technical equipment are really protected if a voltage stabilizer is connected to them. An electromechanical voltage regulation device, for example, is ineffective in working with heating equipment equipped with a heating element. The same applies to equipment with increased inrush currents, for which voltage drops are a natural condition for operation.
Conclusion
In choosing the right stabilizer you need to consider a lot of different aspects. And perhaps the most critical decision will be the initial determination of the type of device. Which stabilizer is better - relay or electromechanical? If we are talking about domestic use, then electromechanics is more profitable because of resistance to loads and accuracy of adjustment. As for the relay models, they show themselves well in cases where you need to adjust the network parameters in unpredictable conditions. This applies to differences in wide ranges, and external influences, and other factors that may affect the operation of the device.
