Schneider Electric ATV18U72N4 Frequency Converter

Schneider Electric's Altivar 18 ATV18U72N4 Frequency Converter provides precise, adjustable speed control for 4 kW (5 HP) three-phase asynchronous motors. Operating from a 380–460 V AC three-phase supply (50/60 Hz) with 380–460 V AC three-phase output, it delivers up to 9.2 A and a tunable output frequency of 0.5–320 Hz, housed in a panel-mount, IP20-rated Type 1 enclosure. Used in conveyors, pumps, fans, compressors, packaging machinery, and material handling, it's also commonly applied in water and wastewater treatment, HVAC equipment, and other industrial processes where reliable motor speed control and energy-efficient operation are essential.
