DESCRIPTION: The Parus-7 is a single-phase voltage stabilizer for an apartment or home with a maximum power of 7 kW. It belongs to the Volter Parus series and is designed to provide stabilized voltage to all types of electrical consumers when powered from a grid with poor voltage quality. This is a double-conversion device without energy storage. Advantages: Low noiseIncreased noise immunityHigh speedOperation at sub-zero temperatures and high humidityIncreased fire safetyMaximum number of protectionsConvenient connectionDoes not distort the sine waveResistance to mechanical stress Characteristics: Type - inverterPhase - single phaseEfficiency, % - 98Input range - 110-330 VResponse time, ms - 1Noise level, dB - 34-40, depending on the loadMaximum current, A - 16Maximum power, kW - 3.5Mounting method - wall-mountedCooling - forcedMax.
