Telemecanique ATV18D16N4 Variable Frequency Drive

The Telemecanique Altivar ATV18D16N4 Frequency Inverter is an 11 kW (15 HP) panel-mount variable frequency drive that precisely controls speed and torque for three-phase asynchronous motors in industrial automation. It accepts 380–460 V AC three-phase input, provides 380–460 V AC three-phase output up to 22 A with a 33 A transient (60 seconds), and supports an output frequency range of 0.5 to 320 Hz at a 50/60 Hz supply. Widely used in conveyors, pumps, fans, compressors, packaging machinery, and material handling equipment, as well as water and wastewater facilities and HVAC systems, it enables adjustable speed, controlled acceleration, and energy-efficient operation. For retrofit or upgrade projects, common replacements include the Schneider Electric ATV320D11N4B.
