Schneider Electric ATV212HU55N4 Overview

The Schneider Electric ATV212HU55N4 is a variable-speed drive from the Altivar 212 range. It is designed for controlling asynchronous motors in HVAC applications, specifically pumps and fans. The drive has a motor power rating of 5.5 kW or 7.5 hp and operates on a supply voltage range of 323 to 528 VAC. It offers a high degree of flexibility and control for efficient motor operation. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry AC Drives from other manufacturers such as Modicon and ABB.


As part of the Altivar 212 range, the ATV212HU55N4 provides reliable motor control with advanced features. The drive supports various communication protocols, including METASYS N2, LonWorks, BACnet, Modbus, and APOGEE FLN, enabling seamless integration into different building automation systems. It offers an IP21 degree of protection, ensuring its resistance to solid objects and providing a level of protection against moisture.

With an apparent power of 9.1 kVA at 380 V and a continuous output current of 12 A at 380 V, the ATV212HU55N4 delivers the necessary power to drive the connected motor. It also has a maximum transient current of 13.2 A for 60 seconds, allowing for temporary high-demand situations.

The drive supports a speed range of 0.5 to 200 Hz, providing flexibility in motor speed control. It has a speed accuracy of +/- 10% of the nominal slip from 0.2 times the rated motor torque (Tn) to the rated torque (Tn). This level of accuracy ensures precise control over motor speed, allowing for optimal performance in HVAC applications.


The ATV212HU55N4 features local signaling with a red LED indicator that indicates when the DC bus is energized. It provides electrical isolation between the power and control terminals, ensuring safe operation and protection against electrical faults.


For electrical connections, the drive supports various cable types and sizes. It has removable screw terminals for ease of installation and maintenance. The drive includes an internal supply for reference potentiometer and digital inputs, as well as an external supply for digital inputs with overload and short-circuit protection.


The drive offers multiple analog and discrete inputs and outputs for versatile control and monitoring. It includes two analog inputs that can be configured for voltage or current signals and two analog outputs for voltage or current signals. It also provides two discrete inputs and two configurable relay outputs for flexible control options.


With a compact design, the ATV212HU55N4 has a width of 142 mm, a height of 184 mm, and a depth of 150 mm. It weighs 3.35 kg, making it suitable for installation in space-constrained environments.

In terms of motor control profiles, the drive supports voltage/frequency ratio control, flux vector control without a sensor, and energy-saving voltage/frequency ratio control. It includes features such as motor slip compensation and automatic acceleration and deceleration ramps for smooth and efficient motor operation. The drive also offers protection against various faults and abnormalities, including overheating, short circuits, input phase breaks, and overvoltages.

In summary, the Schneider Electric ATV212HU55N4 is a versatile variable-speed drive designed for HVAC applications. With its advanced motor control capabilities, communication options, and comprehensive protection features, it provides efficient and reliable operation for pumps and fans.
