DESCRIPTION: The Smart-27 is a three-phase voltage stabilizer for an apartment or home with a maximum power of 9 kW per phase. It belongs to the Volter Smart 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 speedCan be used at sub-zero temperatures and high humidityIncreased fire safetyMaximum number of protectionsConvenient connectionDoes not distort the sine waveResistance to mechanical stress Characteristics: Type - inverterPhase - three phasesEfficiency, % - 98Input range - 110-380 V (per phase)Response time, ms - 1Noise level, dB - 34-40, depending on the loadMaximum current, A - 40Maximum power, kW - 27Mounting method - wall-mountedCooling - forcedInput voltage - 220 V (per phase)Max.
