Schneider Electric ATV28HU29N4U Variable Frequency Drive

Schneider Electric’s ATV28HU29N4U variable frequency drive, part of the Altivar 28 family, is a 1.5 kW (2 HP) adjustable speed drive designed to regulate speed and torque of three-phase asynchronous motors in industrial automation. It accepts 400–460 V AC three-phase input and provides 400–460 V AC three-phase output, with an input current of 6.1 A at 400 V (5.4 A at 460 V) and an output current of 4.1 A, while offering a wide output frequency range from 0.5 to 320 Hz. The drive includes an integrated Class A EMC filter, IP20 protection, and panel-mount with a heat sink, making it suitable for rugged factory environments and straightforward integration into existing motor control circuits. Common applications include conveyors, centrifugal pumps, fans, compressors, packaging machinery, and production lines where precise speed control, controlled acceleration, energy efficiency, and reliable operation are essential.
