Schneider Electric ATV312HU55M3 AC Drive: Optimized Motor Control for Industrial Applications

Overview
The Schneider Electric ATV312HU55M3 AC Drive is engineered for reliable and efficient motor control, specifically tailored for light to medium-duty industrial applications. This drive is part of the ATV312 series, recognized for its versatility and ease of integration into various operational environments. It excels in managing the speed and torque of asynchronous motors, making it a prime choice for applications such as conveyors, pumps, fans, and material handling equipment.

Power and Voltage Characteristics
Designed to operate on a three-phase power supply, the ATV312HU55M3 accommodates a voltage range of 200 to 240 V with a tolerance of -15% to +10%. This adaptability ensures stable performance across diverse global power conditions, making it suitable for installations in regions with fluctuating supply voltages. With a line current rating of 32 A at 240 V and 36.8 A at 200 V, this drive is capable of handling substantial loads while maintaining energy efficiency, which is critical for reducing operational costs in industrial settings.

Efficient Heat Management and Speed Control
The ATV312HU55M3 features an advanced heat sink assembly that effectively dissipates up to 292 W of power at nominal load, preventing overheating and enhancing the drive's reliability and lifespan. Its capability to control motor speeds within a range of 1 to 50 Hz allows for precise adjustments, making it particularly advantageous in applications requiring variable speed operations. This flexibility is essential for optimizing processes such as material transport and fluid movement, where speed modulation can lead to improved efficiency and reduced wear on equipment.

Compact Design and Component Integration
The compact and robust design of the ATV312HU55M3 facilitates seamless integration into existing control panels or enclosures, minimizing the footprint required for installation. While the drive does not include an internal EMC filter, it is engineered to perform reliably in standard environments. For applications with stringent electromagnetic compatibility requirements, an external filter can be employed to ensure compliance with industry standards, thus addressing potential engineering challenges related to electromagnetic interference.

Power and Safety Ratings
With a rated apparent power of 12.8 kVA, the ATV312HU55M3 is adept at driving medium-sized motors and managing moderate workloads effectively. This capacity is particularly beneficial in automation and light industrial processes, where consistent performance is critical. The drive also boasts a short-circuit current rating of 22 kA, providing robust protection
