Schneider Electric ATV18D16N4 Frequency Inverter

The Schneider Electric Square D/Telemecanique ATV18D16N4 frequency inverter (Altivar 18 family) provides adjustable speed and torque control for three‑phase asynchronous motors up to 11 kW (15 HP). It accepts 380–460 V AC three‑phase input and delivers 380–460 V AC three‑phase output with a rated current of 22 A and a maximum transient current of 33 A for up to 60 seconds. The drive supports an output frequency range of 0.5–320 Hz on a 50/60 Hz supply and is designed for panel mounting in industrial motor speed control systems. Typical applications include conveyors, pumps, fans, compressors, packaging machinery, water and wastewater treatment, HVAC equipment, and material handling where precise speed control and energy efficiency are required.
