Schneider Electric ATV18U18N4 Variable Frequency Drive

Schneider Electric’s ATV18U18N4 Variable Frequency Drive, an AC speed drive in the Altivar 18 family (Square D / Telemecanique), provides precise speed and torque control for three-phase asynchronous motors. It accepts 380–460 V AC three-phase input and delivers 380–460 V AC three-phase output, with a 0.75 kW (1 HP) motor rating and 2.1 A output current, and a 0.5–320 Hz output frequency on a 50/60 Hz input. The IP20, panel-mount drive is designed for industrial motor speed control in conveyors, centrifugal pumps, ventilation equipment, compressors, material handling systems, and packaging machinery where reliable acceleration and energy efficiency are important. It is commonly used for equipment replacement, retrofits, energy efficiency upgrades, and new industrial motor control installations in manufacturing environments.
