ATV31HD11N4

The ATV31HD11N4 variable frequency drive from Schneider Electric is designed to provide precise machine control. It operates with a three-phase input voltage range of 380–500 V ±5% while managing a frequency range of 50–60 Hz ±5%. This drive suits applications requiring up to 11 kW (15 HP) of motor power at a nominal frequency of 4 kHz.

It incorporates an integrated heat sink that supports its thermal management. Additionally, the internal EMC filter ensures compliance with relevant standards for electromagnetic compatibility. The output frequency of this device ranges from a low 0.0005 kHz to a maximum of 0.5 kHz, addressing different operational demands.

This drive utilizes a sensorless flux vector control strategy offering constant torque to maintain efficiency across various workloads. It is capable of variable switching frequencies, ranging from 2 kHz to 16 kHz, allowing for optimization according to the application requirements. With an overload capacity of 150 to 170% transient overtorque, it can handle brief peak demands. Protection features include safeguards against overvoltage, undervoltage, overcurrent, and short-circuit conditions to enhance reliability.

Operating under conditions ranging from -10°C to 50°C, the ATV31HD11N4 can maintain performance without derating. The unit is rated IP20 without a cover but achieves IP21 protection at the terminals, safeguarding the internal components from solid foreign objects and moisture ingress. This makes the ATV31HD11N4 versatile for a range of industrial applications needing dependable motor control.
