Schneider Electric ATV28HD23N4 Variable Frequency Drive

Schneider Electric ATV28HD23N4 is an Altivar 28 variable frequency drive with an integrated heat sink, delivering 15 kW (about 20 HP) of output to three-phase induction motors powered from 380–500 V. The drive is rated for 33 A on a 380–460 V supply and 30.4 A at 500 V, and its enclosure measures 245 × 330 × 195 mm with a weight of 9.6 kg. It includes a Class A EMC filter for electromagnetic compatibility and is designed to provide adjustable speed and torque control in industrial automation systems that rely on legacy Schneider Electric equipment. As part of the Altivar 28 family, ATV28HD23N4 is configured for three-phase operation at 380–500 V, enabling reliable motor control in compact installations where space is at a premium. The HD suffix signals the heat-sink option, offering improved thermal performance in cabinet-mounted environments. Typical applications include speed control for machines and equipment that require stable torque and smooth ramping in mid-power automation tasks.
