Schneider Electric ATV320U40N4C Altivar Machine Variable Speed Drive – 4kW, 5HP, 380–500V 3-Phase
Schneider Electric ATV320U40N4C Altivar Machine 4kW / 5HP VFD with 380–500V 3-phase input, 9.5A continuous output, integrated Class C2 EMC filter, Modbus/CANopen communication and advanced safety functions.
Description
The Schneider Electric ATV320U40N4C is an Altivar Machine ATV320 variable speed drive (VFD/VSD) designed for complex industrial machines and motor-control applications. It provides 4kW / 5HP heavy-duty motor power from a 380–500V AC, 3-phase supply, with a compact wall-mount design for efficient installation inside machine frames and control panels.
The drive supports both asynchronous and synchronous motors, including advanced motor-control methods such as sensorless flux-vector control and V/f control. It delivers a continuous output current of 9.5A at 4kHz for heavy-duty operation and supports output frequencies from 0.1 to 599Hz, making it suitable for applications requiring accurate speed and torque control.
The ATV320U40N4C includes an integrated Class C2 EMC filter, Modbus and CANopen communication, and embedded safety functions including Safe Torque Off (STO), Safe Stop 1 (SS1), Safely Limited Speed (SLS), and Safe Maximum Speed (SMS). It also features an integrated braking chopper and supports multiple optional communication modules for industrial networking.
With its compact 140mm × 184mm × 158mm enclosure, IP20 protection and broad I/O capabilities, the Schneider ATV320U40N4C VFD is well suited to OEM machinery, conveyors, material handling, pumps, fans, packaging equipment and other industrial automation systems.
