Product Introduction
When upgrading older, inefficient drives or designing new high-power systems, the Schneider ATV71HD75N4 variable speed drive stands out for its robust performance and advanced control features. Part of the Altivar 71 series, this drive is engineered for complex, high-power machines requiring precise motor regulation. With an integrated EMC filter and a nominal switching frequency of 2.5 kHz, it minimizes electrical interference and ensures smooth operation in demanding industrial environments.
Technical Specifications Breakdown
The Schneider ATV71HD75N4 operates on a three-phase supply of 380 to 480 VAC and delivers a motor power of 75 kW (100 HP). Key parameters include:
- Input voltage: 380…480 VAC -15…10%
- Input frequency: 50/60 Hz
- Nominal output current: 124 A at 2.5 kHz (460 V) and 160 A at 2.5 kHz (380 V)
- Maximum transient current: 240 A for 60 s or 264 A for 2 s
- Output frequency range: 0.1…500 Hz
- Switching frequency: adjustable 1…16 kHz (2.5…16 kHz with derating)
- Overload capacity: 170% for 60 s every 10 minutes, 220% for 2 s
The drive includes a heat sink assembly for effective thermal management and operates at altitudes up to 1000 m without derating. Its IP20 enclosure protects against solid objects larger than 12 mm.
Industry Applications
The Schneider ATV71HD75N4 is ideal for demanding applications such as conveyor systems, pumps, fans, and compressors that require variable speed control and energy savings. In a materials handling upgrade, this drive replaces aging fixed-speed starters, reducing mechanical stress and energy consumption by matching motor speed to load. The integrated EMC filter simplifies compliance with electromagnetic compatibility standards, while Modbus and CANopen communication ports enable seamless integration into existing automation networks.
Compatibility & Integration
This drive supports Modbus (via RJ45 on front face and terminal) and CANopen (via male SUB-D 9 on RJ45) communication protocols. It can be expanded with optional communication cards for DeviceNet, EtherNet/IP, Profibus DP, and more. The Schneider ATV71HD75N4 also accepts I/O extension cards, encoder interface cards, and controller-inside programmable cards, making it adaptable for custom automation solutions.
Selection Guide & Purchasing Advice
Before purchasing the Schneider ATV71HD75N4, verify that your supply voltage matches its 380…480 VAC range and that your motor rating is 75 kW or 100 HP. Ensure the installation environment stays within -10 to 50 °C and at altitudes below 1000 m (or derate accordingly). For shielded motor cables, keep lengths under 100 m (328 ft).
