ATV32HU11N4

Schneider Electric’s part number ATV32HU11N4 belongs to the Altivar 32 series and functions as a variable speed drive. This device is designed to provide flexible control for motors rated at 1.1 kW, making it suitable for a variety of applications requiring precise speed management. It operates efficiently within a supply voltage range of 380 to 500 volts AC and can handle up to 1.5 horsepower.

The device is designed to work on a supply frequency that ranges from 50 to 60 Hz, while the network frequency varies from 47.5 to 63 Hz. It features a nominal output current of 3 A and can accommodate maximum transient currents up to 4.5 A for a duration of 60 seconds, providing additional flexibility during startup or overload conditions. The drive allows an output frequency adjustment from as low as 0.0005 kHz up to 0.599 kHz, with a nominal switching frequency set at 4 kHz.

For applications with variable load requirements, the switching frequency is adjustable between 2 kHz and 16 kHz to optimize performance. In open-loop mode for asynchronous motors, this drive offers a speed range spanning from 1 to 100, ensuring that users can achieve the desired operational velocity. The accuracy of speed control is rated at ±10% of the nominal slip while torque performance is maintained with an accuracy of ±15%. Additionally, transient over torque capabilities range from 170% to 200%, accommodating increased starting demands effectively. Overall, the ATV32HU11N4 is engineered to deliver reliable performance in variable speed applications.
