Motor Power and Voltage Flexibility

With a motor power rating of 18.5 kW (equivalent to 25 hp), the ATV71HD18N4 AC drive can efficiently handle large loads and intensive applications. Its power supply voltage range of 380 to 480 V, with a tolerance of -15% to +10%, allows it to be used confidently across various industrial environments. The unit’s broad voltage compatibility ensures stable operation, even when power supplies fluctuate. This feature is invaluable for facilities with heavy machinery, where a steady, high-power drive is crucial for smooth performance and uninterrupted workflows.

Current Ratings and Energy Efficiency

The ATV71HD18N4 offers high efficiency in managing the current load. It has a line current rating of 37.5 A at 480 V and 45.5 A at 380 V, giving it adaptability across multiple voltage environments. For output, the drive has a nominal current rating of 34 A at 460 V and 41 A at 380 V, designed to support heavy-duty applications while maintaining efficient power consumption. The drive also features a prospective line Isc of 22 kA in a three-phase configuration, which makes it suitable for high-current demands without compromising safety. With a nominal switching frequency of 4 kHz, the drive optimizes energy usage, which also helps to reduce operational noise.

Frequency and Transient Current Capacity

The ATV71HD18N4 stands out with its wide output frequency range, which extends from 0.1 Hz to 599 Hz, allowing for a high degree of control over motor speed. This flexibility in frequency management makes it suitable for various applications, from precise speed adjustments to high-power operations. Additionally, the drive’s transient current capacity ensures it can handle the brief surge in power demand. It supports a maximum transient current of 61.5 A for up to 60 seconds and 67.7 A for up to 2 seconds, which is particularly useful for applications that experience high load fluctuations.

Durable Design with Heat Sink Assembly

The ATV71HD18N4 is built with durability in mind. It features a heat sink that helps manage heat dissipation during high-load operations. This design enables the drive to perform reliably in demanding environments, reducing the likelihood of overheating and minimizing downtime. The heat sink assembly makes the drive more straightforward to install in compact spaces, as it can handle continuous operation without additional cooling components.
