Schneider Electric ATV320U15N4B Variable Frequency Drive

The Schneider Electric ATV320U15N4B Altivar 320 AC Drive is a 1.5 kW (2 HP) variable frequency drive designed to precisely regulate speed and torque for three-phase motors in industrial motor control systems. Operating from 380–500 V AC three-phase input, it provides a continuous output of 4.1 A with a frequency range of 0.1 to 599 Hz, and supports V/F control, sensorless vector control, and synchronous motor control. This Altivar 320 unit includes integrated Modbus and CANopen communications, Safe Torque Off (STO) with SIL 3 safety, and an EMC filter Class C2, all housed in an IP20, fan-cooled, book-style panel-mount enclosure suited to indoor control cabinets. Designed for 50/60 Hz operation, it is commonly used in conveyors, packaging machines, material handling systems, and automated production equipment to drive asynchronous or synchronous motors with high performance in a compact installation. It integrates readily into PLC-based systems for seamless retrofit, replacement, or system expansion in industrial networks.
