Voltage stabilizer MV LCD "ENERGY" (220 V, 3.0 kW)

The single-phase voltage stabilizer CH-LCD “ENERGY” is designed to provide power to various consumers in conditions of large voltage deviations in 220 V networks. For three-phase networks, it is possible to use three voltage stabilizers connected in a star configuration. Advantages of high-speed stabilizers CH-LCD “Energy” Recently, ultra-cheap voltage stabilizers made in China, Wusley, SOLBY, SASSIN, etc., have become widespread (many domestic manufacturers also produce something similar). Why are they so cheap? This is not a normal high-speed stabilizer with many triacs or relays, but simply put, a “latr with a motor.” As the main advantage, a high accuracy of setting the output voltage of 220 + -3% is declared. But such accuracy is usually not needed (all devices, in accordance with GOST, are required to operate in the range of 185 - 245 V, i.e. + -10-15%). But as a result of the fact that the motor cannot quickly adjust to a power surge, the devices can burn out. The voltage adjustment time is 0.5 seconds for every 20 V. That is. if there was a surge in the network to 300 V, at the output of the stabilizer, at first there will also be 300 V, and only after 2 seconds 220 V will be established. And during these seconds, some equipment may burn out... If such voltage stabilizers make sense to be used anywhere , then, for example, in networks where the voltage is constantly very high (for example, 260 V). Consider, for example, the following situation. The voltage is constantly low, let's say 170 V (outside Moscow, a quite common phenomenon, due to bad wires and/or large industrial enterprises). Let's say in the evening (when the enterprises finished work), the voltage jumped to 240 V (and this could be sharp). The latr was adjusted to increase the voltage by a factor of 1.3. That is, when the input voltage jumps (and, by the way, does not exceed 250 V, i.e. it will definitely be missed), the output voltage will be 240 * 1.3 = 313 V. And only after 2.5 seconds will it return to 220 V. Similar things can be caused by elevators, welding equipment, etc. There may be other reasons for a sharp increase in voltage even up to 380V. We encountered the following: short circuit of the second phase to neutral (for reasons such as confusion by an electrician, a fire in a panel or a neighboring house, even with a fall of an electric pole). All of the above problems are eliminated by the use of high-speed stabilizers CH-LCD “Energy”. Features of CH-LCD “Energy” stabilizers: • Extended range of input voltages while maintaining output voltage in accordance with GOST requirements. • Increased speed and accuracy. • Withstand overload for 5 seconds. • Double current protection (electronic fast-acting and fuse) • Noise filtering (varistor and capacitor surge suppressor). • Lightning protection (if there is a high-quality grounding line) - eliminates induction high-voltage pulses that occur in wires during a lightning strike. • When starting up, the stabilizer connects consumers only after self-checking and monitoring the supply network. • The control circuit is implemented on a microcontroller, providing “soft” switching, a high degree of protection against various network and load failures, and increased reliability of the product as a whole. • No maintenance required. • Certificate of Conformity No. ROSS RU.ME68.B00795. Most of the office equipment used in Russia is imported. It is not always designed to our standards. For example, you often find equipment designed to operate at a nominal voltage of 230 V and designed for a voltage tolerance of 10%. Such equipment has the right not to work under conditions that are quite standard in our country. For such cases, the CH-LCD "ENERGY" provides a switch that allows you to select which stabilized voltage will be at the output - 220 or 230 V. Technical characteristics of voltage stabilizers.
