The Schneider Electric ATV320U07N4B is a 0.75 kW variable frequency drive (VFD) from the Altivar Machine ATV320 series, designed for complex machine applications on three-phase 380...500 V supplies. Supplied in book format for enclosure mounting, it includes an integrated Class C2 EMC filter and a built-in braking resistor. Standard communication covers Modbus serial and CANopen, with optional expansion modules for additional fieldbuses.
