Schneider Electric ATV320U15N4B Variable Frequency Drive

The Schneider Electric ATV320U15N4B Altivar 320 1.5 kW variable frequency drive delivers precise speed and torque control for three-phase motors in industrial automation, including packaging lines, conveyors, material handling systems, and textile machinery. It operates from 380–500 V AC three-phase, delivers 4.1 A continuous, and covers a broad 0.1–599 Hz frequency range, with control modes that include V/F control and sensorless vector control. Safety is built in with Safe Torque Off (STO) and SIL3 capability, and communications include Modbus and CANopen with expandable Ethernet options, all housed in an IP20, fan-cooled, panel-mount (book format) enclosure. Often chosen for retrofit or replacement in complex machine environments, the ATV320U15N4B aligns with common replacements like ATV320U15N4C.
