Calm IS1000

Advantages: + Response time real 0 ms + Huge operating voltage range at the input. Incredible. From 90 to 310 volts! + It is guaranteed always, in general, always at the output the required voltage (I mean that there are models for 220,230 and even 240! V, depending on which equipment you connect, do not make a mistake when buying) + No clicks, hums, etc. , only quiet, soft rustle of cooling fans + There is a backlit display + Mounted on a wall or other surfaces + Keeps power in case of micro-drops of electricity for 200 ms + Pleasant assembly and manufacturing of parts, many manufacturers, even eminent ones, sin with crooked and oblique moments

Disadvantages: - The power cord is short - Still, there is active cooling, and there is weak, but the noise will obviously suck the dust inward - Not cheap (but cheaper than similar devices and not) - It may be better that the L-shaped plugs of consumers stuck into it look with their tails up and down, and not back and forth (if it hangs on the wall, then an absolutely impossible option)

Comment: In the house, power surges are frequent, a primitive stabilizer like POWERCOM TCA-2000 turned out to be absolutely useless. In the new boiler, on the very first day of launch, the transformer burned out. The realization of the need for really effective protection has come. And only Calm can now offer a line of devices of this type. Not bulky, not noisy, not super-expensive, but very modern, and providing guaranteed 220V output. Without any but in the form of ranges, milliseconds, tolerances and deviations, etc. Excellent machine. It happens both completely white and silver, like mine.

Advantages: Good build quality. Good informational support of the manufacturer (promptly answer questions by e-mail). Pure sine wave output. Stable output voltage with an accuracy of one volt. Backlit LCD display. The ability to view the voltage at the input and output of the stabilizer, as well as the power consumption of the load.

Disadvantages: Maybe not a lot of noise from the forced cooling fan.

Comment: It is used to provide stabilized voltage to a 49 '' TV, soundbar, router and Sony PS4 Pro. For these tasks, this stabilizer is enough with a margin.

Advantages: Declared operating voltage range at the input Response time, in reality nothing happens during voltage surges in the operation of the equipment The output is a stable sinusoid, in my case 220V Display High-quality assembly Honest guarantee Convenient wall mount included

Disadvantages: The price is high, but the quality is not cheap

Comment: As they say, when you buy and immediately after opening the package you like a thing - it means you bought what you need. When starting heating in a country house, a prerequisite for a guarantee for a pellet boiler and a heating system was the presence of a voltage stabilizer. The installers suggested Cyber ​​Power CSP-600E, but read reviews on its work with TP boilers and did not dare, somehow cheaper Chinese ones also did not risk - a pure sinusoid was needed. In our work, we use server UPS produced by Shtil for about 2 years, the period is probably not long, but there are no complaints about work and maintenance so far, and this fact, as well as the positive reviews that I found on the internet for this manufacturer, played in favor of my choice. may not have touched on this before, but was delighted that they also have household UPSs. I stopped the choice on IS1000, probably it would have been better for IS1500 in terms of power, but it was really biting on money ... What can I say, I do not regret a single drop of money spent. It has been working for almost 2 months, there are no complaints, at the input there are jumps, as probably in all the Moscow region, the voltage is from 210V to 244V, mainly 240 and higher, at the output there are stable 220V. A couple of times the boiler automatics recorded even a short-term lack of voltage in the network, but the boiler did not stop, which pleases, it probably was all the same milliseconds .. but it did not stop. In terms of power at the time of start-up, it works similarly to the maximum (judging by the load scale), but has never complained about overload, it works out normally. The fan is noisy, of course, but in the boiler room the airflow is much louder, and the supply of pellets to the boiler is noisy .. so you can't really hear it against the general background. In general, I am satisfied with the device and calm about the technique that he defends.

Advantages: - Ideal 230V and sine output. No artifacts in case of sharp jumps and drawdowns. - Informative display: input / output U, current load, temperature. - Metal body, nice design, solid performance. - Reliable circuitry, no magnetic fields. - Doesn't click like relay switches.

Disadvantages: - Expensive, but nothing like this is cheaper in our market. - There is a little noise from the fan, but this is more of a nitpick.

Comment: The money spent is not a pity. Used to protect expensive industrial sewing equipment. Highly recommended for protecting high-precision machines with motors. For consumer electronics, this is redundant protection in my opinion.

Advantages: Nice device of the international level. smooth voltage regulation. No surges as in electronic devices. Possibility of visual observation of load changes. I use it to power an audio system. Very good.

Disadvantages: One drawback, if placed at the table: -noise. I'm thinking of taking it to the garage. I hope He won't be cold there.

Comment: The best gimbal for everyday use. I recommend it to everyone.

Advantages: Stabilizes! Nice appearance. Acceptable fan noise, noticeable only when switched on and under heavy load.

Disadvantages: Price

Comment: An excellent power stabilizer, it performs its function. I do not have special equipment to test the perfect sine wave and no delays in damping voltage surges, but my equipment that is sensitive to the quality of the power supply now works without interruption.

Advantages: I bought a single-phase AC voltage stabilizer Shtil InStab IS1000, factory # 1905.ShP455.1.055 for a floor-standing gas boiler BOSCH, and the second, the first, with a service life of 10 years, served faithfully for 17 years without complaints and repairs. voltage and Chinese stabilizers are out of order, and our "Calm" at least that! Therefore, when it was necessary to replace it with a new one, there were no doubts, only "Calm".

Disadvantages: They just don't exist!

Comment: compact, noiseless, you can put and hang on the wall, and the design is nice, and for such sensitive gas boilers as BOSCH and BUDERUS it is ideal - it will not let you down. I recommend Calm to everyone!

Advantages: Ease of installation. Small size. Excellent technical characteristics. Convenient indication - you can see the current load on the display. Two outlet sockets.

Disadvantages: Slight noise from the cooling fan, but this is not critical. it is installed in the boiler room of the house.

Comment: The stabilizer was bought to provide the boiler room with a stable voltage. All circulation pumps with expensive automation and boilers are connected to it.

Advantages: Solid appearance. Long cable to connect to the network. Russian assembly. The presence of not only an indication, but an informative LCD display. Excellent performance. Instant surge protection.

Disadvantages: Only two sockets for connecting the load. Slight cooling fan noise.

Comment: Acquired for connecting household appliances demanding power supply indicators (TV, etc.). I connected a TV, router and photo frame. For such tasks, I think this voltage stabilizer is enough. Brief characteristics are indicated on the packaging.

Advantages: Stable work, informative display

Disadvantages: When connecting a gas boiler, it is important to observe the phase, it would be great if the device helps to determine where the phase is, otherwise you have to take a tester. Therefore, the only drawback: it is difficult to pierce the socket with a screwdriver tester to determine the phase

Comment: The stabilizer provides a stabilized voltage of 220 V in the uninterruptible power supply system of the Ferroli gas boiler, which heats a private house in the Moscow region and provides hot water supply. Teplokom-1000 was used as an uninterruptible power supply. The input voltage in the house often exceeds 250 V (the photo shows that at the time of filming it is 247 V!), The stabilizer makes it possible to work reliably for the UPS and the boiler, stabilizing the voltage up to 220 V. The indicator is very informative, allowing you to control all the necessary parameters in the boiler power supply: input / output voltage, power.
