DESCRIPTION: The Volter 9PTTM is a single-phase voltage stabilizer for apartments and homes with a maximum power of 9 kW. It belongs to the Volter PTTM 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 - single phaseEfficiency, % - 98Input range - 130-330 VResponse time, ms - 1Noise level, dB - 34-40, depending on the loadMaximum current, A - 40Maximum power, kW - 9Cooling - forcedMounting method - wall-mounted / floor-standingMax.
