The Schneider Electric ATV71HD55N4 is a powerful AC variable speed drive engineered for high-demand industrial applications. As part of the advanced Altivar 71 series, this drive delivers precise motor control, increased energy efficiency, and reliable operation in complex machinery. Rated for 55 kW (75 hp) motors on a three-phase 380–480 V supply, it is ideally suited for equipment in industries such as material handling, process manufacturing, pumping, and HVAC systems.
This model is purpose-built to manage complex, high-power machine operations with enhanced motor dynamics. It supports advanced control algorithms such as Flux Vector Control (FVC) with sensors and Sensorless Flux Vector Control (SFVC), enabling superior torque and speed regulation under all load conditions. The ENA (Energy Adaptation) system dynamically compensates for load imbalances, enhancing operational efficiency and motor longevity in fluctuating environments.
Operating at a nominal output current of 116 A (at 2.5 kHz, 380 V), the ATV71HD55N4 can deliver high torque consistently across a broad operating range. It handles up to 96 A at 460 V and 120 A at 380 V, with a maximum transient current of 174 A for 60 seconds, supporting peak load demands without performance loss. The drive ensures precise control for low and high-speed applications with a switching frequency adjustable between 1 kHz and 16 kHz and a frequency output range from 0.1 to 500 Hz.
Equipped with an integrated EMC filter, the ATV71HD55N4 helps reduce electrical noise and ensures compliance with industrial electromagnetic standards. It supports motor cable lengths of up to 100 meters shielded and 200 meters unshielded, offering flexibility for equipment layout. The unit comes in a heat sink assembly style, providing effective thermal management and reliability during continuous duty cycles. With a prospective line short-circuit current (Isc) of 22 kA, it can operate safely in fault-prone environments.
The ATV71HD55N4 is now available through MRO Electric and Supply, with free shipping and a 2-year warranty. MRO provides expert support and fast delivery, ensuring minimal downtime and maximum operational continuity. Whether upgrading existing systems or commissioning new projects, this drive delivers power, flexibility, and performance across various industrial automation needs.
