DESCRIPTION: The Volter 27 PTTM is a three-phase voltage stabilizer for apartments and homes with a maximum power of 27 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 - three phasesEfficiency, % - 98Disconnection in transit - 260±5 VResponse time, ms - 1Noise level, dB - 34-40, depending on the loadInput range - 130-330 V (per phase)Maximum current, A - 40Maximum power, kW - 27Mounting method - wall-mounted / floor-standingCooling - forcedOutput voltage - 220 V (per phase)Stabilization accuracy - ±0.5%Max.
