Outdated Product
Single-phase wall-mounted thyristor voltage stabilizer with increased power, capable of providing comprehensive protection for household and professional equipment in an urban apartment, small cottage, and small office (6-10 workstations). The declared total power of the device is 10,000 VA, which corresponds to a nominal active power of 7 kW. These characteristics are sufficient for fully servicing a household with refrigerators, washing machines, air conditioners, televisions, circulation and submersible pumps, gas and solid fuel boilers, and telecommunications equipment. It can also be used in small retail outlets or cafes to protect retail and cash equipment, including POS terminals, DVR/NVR video recorders, and surveillance cameras. The single-phase stabilizer Luxeon EWR-10000 employs...a step-switching principle of the autotransformer windings. However, unlike budget relay models, this device has no mechanical moving parts, and the functions of the switches are performed by powerful semiconductor keys - thyristors. When the network voltage deviates from the norm, the microprocessor control system instantly calculates which of the autotransformer windings to switch the load to, in order to compensate for the deviation, and sends a signal to the corresponding thyristor key in less than 20 ms. Electronic switching ensures silence, high reaction speed, and impressive durability.

Model overview based on user reviews  
The Luxeon EWR-5000 is a modern triac-based voltage stabilizer designed for reliable performance with a power capacity of 5 kVA. It operates silently under normal conditions and features a digital voltmeter for easy monitoring. The stabilizer offers a wide input voltage range of 90-270 V, though optimal performance starts at around 120 V. It provides effective protection against short circuits, overloads, and over/under voltage, making it suitable for environments with fluctuating power supply. The device is wall-mountable and passively cooled, with dimensions of 435x310x198 mm and a weight of 17.3 kg. While the instructions could be more comprehensive, the Luxeon EWR-5000 is a solid choice for maintaining stable voltage in homes with inconsistent power, ensuring the safety and functionality of household appliances.

Perfect solution for a small house
27 May 2017 
Our country house is already about twenty years old and for a long time everything was fine with the power supply. Well, it happened that the voltage dropped to 190 volts, but this did not affect the operation of household appliances and the heating gas boiler. But three years ago, five more houses were built on our street, and the former neighbors were replaced by more energetic young people. In short, with tension, a complete tryndets began. Above two hundred volts on a voltmeter can only be seen in the early morning, and in the evenings the voltage hangs around 160-170 volts. Of course, home technology did not like it. I had to buy a stabilizer.
This is a modern triac model, not some relay nonsense. In normal mode, it works completely silently, and only with force majeure it starts to squeak disgustingly. The stabilizer is powerful, designed for a constant load of up to 7 kW. I didn’t load it clearly to the maximum, but for a long time at a load of 5.7 kW it worked without problems. The stabilization quality is good, the deviation is more than 5-7 volts up and 10 volts down. It has two visual luminous digital indicators. And a whole host of defenses. The upper voltage limit is about 270 volts, the protection is triggered higher, which is logical.
It is stated that it can operate with an input voltage of 90 volts. This is not entirely true, more or less normal operation starts at 120 volts. At lower values, it disables the output with an error message. However, in my house it has not yet come to such a tin and I hope that it never will. Instructions are incomplete and in need of improvement.
Never buy, think twice, and never buy again

Does not work correctly. It does not equalize during a sudden voltage surge. Also, after turning off the light, when the voltage is applied, the machine often cuts out, which added a thousand inconveniences in the current conditions.
Nothing
Does not perform its functions
