Fluctuations in electrical currents in electrical networks badly affect the performance and quality of electrical appliances, various equipment powered by electrical networks. The sources of such failures are often accidents at supplying stations, poor weather conditions, causing high electrical discharges in the atmosphere. All this leads to the failure of electrical appliances, often such devices can no longer be reanimated. In contrast to this negativity, a system of protection against power surges in the form of stabilizers was created.
Domestic protection
The market for electrical appliances for protecting electrical networks is replete with representatives of this equipment. It has long been noted that domestic devices are not inferior to anything, and sometimes even surpass foreign analogues. A striking example of the protective products of electric networks are voltage stabilizers "Calm".
Stabilizers of the same name company are issued from the date of its foundation. Full cycle production was organized in 1994 at the company's own facilities. The plant is located in the city of Tula, the products are of high quality, it is certified and meets all the norms and standards of GOST.
The plant’s products are ordered by such large organizations as the RF Ministry of Defense, domestic television and radio companies, and federal security services. But the prices of "Shtil" voltage stabilizers are quite affordable for the ordinary buyer and vary from 4,000 to 18,000 rubles, depending on the models.
Some models of stabilizers have been specially made to protect gas boilers, which maximize the safe operation of boiler devices.
Right choice
The company "Calm" produces a wide range of profile products, which are present and electronic stabilizers, and apparatus for boiler rooms, and uninterruptible power supplies. All manufactured equipment at the highest level is adapted to the needs of domestic electric networks. After installing the stabilizers, all output parameters clearly comply with the European standard.
When choosing the "Calm" voltage stabilizers, it is necessary to take into account such factors as the power of the device, data of the incoming voltage and the final output range.
Judging by consumer reviews, the products of the company "Calm" proved to be the best, it has a high reputation among users not only in Russia but also in Moldova, Belarus and several other neighboring countries. This is due to constant monitoring at the factory over the quality of the finished product. Control is carried out at all stages, from design to equipment testing.
Area of use
The voltage stabilizers "Calm" are used in almost all areas of life and activity where electricity is used. The device finds its place in work offices, residential buildings and apartments, in computer rooms, as well as in industrial organizations. A stabilizer is needed to protect measuring equipment, copy machines, refrigeration equipment and televisions. The device copes well with protection against power surges in power grids of both domestic use and large-scale industrial use. Many security networks cannot do without stabilizers.
The voltage normalization device is connected to the network after the electric meter or distribution block. The stabilizer is equipped with terminals - phase and zero, to which the corresponding voltage wires are connected. When connecting the output lines, it is also necessary to observe the polarity so as not to provoke a short circuit.
General characteristics
The company "Calm" produces three-and single-phase voltage stabilizers. Many varieties of devices by the manufacturer were combined in several series. Many stabilizers have the function of filtering industrial and atmospheric interference, which often occur in electrical networks.
The main stabilizer assembly is an autotransformer. The quality of work of all equipment directly depends on the amount of winding. Switching through the autotransformer windings and voltage control is carried out using a control microprocessor. The adjustment is characterized as electronic step.
The “Stihl” voltage stabilizer housing is made of sheet steel up to 1.2 mm thick. To monitor the operation of the device and display modes on the front wall are LED indicators, and in some models, digital display panels. Devices with low power are equipped with Euro outlets, more powerful instances are equipped with terminal blocks.
Some models come with a bracket for mounting the unit on the wall, which greatly expands the mounting area.
Models of stabilizers "Calm"
Calm electronic voltage stabilizers are divided into several series. The lineup is represented by such devices:
- R series (Standard);
- P series;
- T series (Thermo);
- ST series (Thermo-Sim);
- SP series.
All models have high performance, long service life, subject to proper operation.
The best models for residential applications are the R, T and ST series. The first two types of the series cope well with network protection for household appliances, computer equipment.
The voltage stabilizers "Calm" for boilers should be selected from a series of T and ST.
R Series Stabilizers
The line of these devices is the largest of the entire family. In its composition it contains 15 single-phase and 11 three-phase devices with a capacity of up to 100 kVA. The voltage stabilization accuracy level in this category is about 5%.
The R series includes reliable models, such as:
- "Calm" R400 T. Cope with the protection of heating equipment, the total capacity of which does not exceed 400 kVA. There is the possibility of mounting on the wall. When a significant excess voltage is automatically turned off.
- Calm R400 ST. In the device, instead of a relay, semiconductor triac keys. As a result, the stabilizer works silently and the response level is an order of magnitude higher, and the error is reduced to 3%.
- "Calm" R600 T. The device with relay keys. Outside the unit there are two Euro sockets, which is convenient for connecting additional equipment that needs protection. There is a filter that removes electromechanical interference. The total protection power is not more than 600 kVA, there is an indicator warning of the operation of the device. The ST model stabilizer of the same power is more silent, automatically shuts off when overvoltage, can be mounted on the wall.
The most powerful models of the R series
Also in this series there are other models with a wide range of operating voltage.
- "Calm" R800 T - a single-phase stabilizer is designed for serial connection of various boiler equipment. The input voltage is stepwise switched.
- "Calm" R 1200 SPT - a popular model with a wide range of input voltage, silent operation, minimal error of the output voltage. The device uses triac microchips. Suitable for use in boiler rooms.
- "Calm" R2000 SPT and R3000 SPT - characterized by a high level of performance, safety. The latter is due to the double insulation of the case. Auto protection, powerful output voltage, line filters. The total power of the connected equipment is 2 and 3 kVA, respectively. The "calm" 3000 can equalize the voltage at a very low input, up to 140 V.
Popular Model - Calm R6000
The Shtil R6000 voltage stabilizer is intended for joint functioning with very powerful equipment, for example, heating devices, photocopiers, technological and trade refrigerators.
The stabilizer looks like a monolithic block of floor placement. On the front side there is an indicator panel and a key to turn off the device.
For this device, the operating range ranges from 135 V to 275 V, it is equipped with automatic overvoltage protection at an input of more than 300 V. After the normal voltage in the external network returns, the device reconnects to operation.
It has connectors in the form of terminal blocks, equipped with forced cooling through a programmable fan. There is an output line filter, the transformer winding consists of copper, an electronic stabilizer with thyristor power switches. Reviews confirm that the devices are reliable and do their job 100%.
