Frequency inverter ATV212 3-phase 380/480VAC 50/60Hz 37kW 79A IP21 ATV212HD37N4

Frequency inverters for drive control

This Schneider Electric Altivar 212 frequency inverter is a reliable solution for precise control of asynchronous motors. Designed for HVAC applications such as pumps, fans and compressors, it offers efficient and easy-to-use speed regulation. The device is adapted to operate in power networks with a voltage of 380V to 480V AC and a frequency of 50/60Hz. Its compact dimensions – 240 mm width, 550 mm height and 244 mm depth – facilitate mounting even in limited space. The IP21 protection class provides protection against touch and ingress of solid objects.

Functionality and Communication

The ATV212 inverter offers a wide range of communication possibilities, making it an ideal choice for both simple applications and advanced automation systems. It has three digital inputs, one analog output and two analog inputs, allowing flexible adaptation to different control needs. It supports the Modbus protocol, as well as other communication protocols, ensuring integration with building management systems (BMS) and industrial automation platforms. Additionally, it has a PC connection for easy configuration and diagnostics. The presence of an RS-485 port allows for serial communication.

Application and Performance

This inverter is designed for both industrial applications and in residential and commercial buildings. The maximum power output is 37 kW with a rated current of 79A. The ability to operate with an output frequency of up to 200 Hz allows for optimization of the motor's operation in various applications. The relative tolerance of the network voltage is 10%, and the network frequency – 5%, which ensures stable operation even in the event of voltage fluctuations. This makes the device resistant to interference and ensures reliable operation for a long time. Integrated diagnostic functions facilitate the identification of any problems and minimize system downtime.
