A voltage stabilizer is considered to be of good quality if it manages to correct the voltage in time, has a wide adjustment range (that is, it is capable of, for example, turning 150 Volts into 220 Volts without loss of power) and it is important that such a stabilizer lasts a long time, that is, it has a guarantee of 2-3 years. Today we have prepared a photo review of the operation of the voltage stabilizer SUNTEK servomotor type, with a power of 1000 VA. A photo of the stabilizer and an overview of its technical parameters are below.
Power is not very important for us today, because we will check what output voltage this voltage regulator will give us. To do this, we will take the variac transformer SUNTEK RED series 1000VA , and we will use it to change the input voltage for the stabilizer. In the end, this is what we ended up with.
Well let's go down. I must say that the stabilizer gently reacts to changes in the input voltage and manages to quickly correct it. So we did not go down to 174 volts. The stabilizer gives out stable voltage.
Not everyone in the house has 158 volts, but the stabilizer is able to equalize such voltages. As we can see, no indicators turn on, which means that the stabilizer is operating normally.
It's time to test the incredibly low voltage, 140 volts. The output voltage dropped a little to 211 volts, but still it meets the power supply standards. The result seems to be good.
Let's look at the top. If your house is located close to the transformer, then often you do not get low voltage, but rather high voltage. So the first step.
Well, straight up. 275 volts. Dangerous voltage. The stabilizer corrects and outputs 241 volts at the output. Almost the upper limit of the allowed voltage (242 is the allowed upper limit), so we have moved from a dangerous voltage to a safe one. The stabilizer and here was able to do its job.
Our opinion is pretty good. The stabilizer did all its work as stated in the manual.
Where would such a voltage stabilizer with a power of 1000 watts fit.
Such a voltage stabilizer will perfectly protect your computer with all its peripherals (printers, scanners, plotters, etc.) even at a professional level. If you have a TV, such a voltage stabilizer will be an additional protection for it and all its equipment. Gas boiler - yes! Refrigerator yes! (but you just need to check first, there are refrigerators with a lot of power) Musical equipment - yes! Let's go out of town, to a cottage - take it with you, your equipment will be happy with a stable voltage.
