SCHNEIDER Inverter ATV71HC11N4 110kW
We sell original quality SCHNEIDER Inverter ATV71HC11N4 110kW products at competitive prices. We are the solution to your needs ,The Schneider Electric Altivar 71 (ATV71HC11N4) is a high-performance frequency inverter designed for constant torque applications and heavy-duty industrial processes. This specific model is a high-power unit, typically used in demanding environments like mining, oil and gas, and water treatment.
Technical Specifications
Power Rating: 110 kW (150 HP)
Mains Voltage: 3-phase AC 380V to 480V (50/60 Hz)
Continuous Output Current: 215 A (at 400V)
Max Transient Current: 322 A for 60 seconds (150% overload)
Protection Class: IP20 (intended for cabinet installation)
EMC Filter: Integrated Class A EMC filter
Key Performance Features
Advanced Control Algorithms: Supports Sensorless Flux Vector Control (SFVC) and Voltage/Frequency (V/f) ratios (2 or 5 points), providing high torque at very low speeds.
Constant Torque: Specially engineered for “heavy-duty” tasks where the load remains constant across different speeds.
Safety Functions: Includes the “Power Removal” safety function (equivalent to STO – Safe Torque Off) to prevent accidental motor starting.
Braking Torque: Capable of high braking torque with an external braking resistor, suitable for high-inertia loads.
Communication & Expansion
The ATV71 is highly modular and fits easily into complex automation architectures:
Onboard Ports: Integrated Modbus and CANopen.
Expansion Slots: Can accommodate optional cards for PROFIBUS DP, PROFINET, DeviceNet, EtherNet/IP, and Modbus TCP.
I/O Extension: Supports additional I/O cards if the standard onboard terminals are insufficient for the application.
Typical Heavy-Duty Applications
Given its high power and high torque capabilities, the ATV71HC11N4 is commonly used for:
Hoisting & Cranes: Precise movement and high starting torque for heavy lifting.
Conveyors: Managing high friction and heavy material flow.
Crushers & Shredders: Handling sudden load spikes in recycling or mining.
Mixers & Agitators: Maintaining constant speed in high-viscosity fluids.
Maintenance and Interface
Graphic Display Terminal: Usually paired with a removable graphic keypad that supports multiple languages and provides diagnostic charts.
SoMove Software: Compatible with Schneider’s SoMove setup software for easy parameter backup and commissioning.
As the Altivar 71 series is now in its “Legacy” or “End of Life” phase (succeeded by the Altivar Process ATV900 series), this unit is primarily sought after for maintenance replacements in existing plants or for critical spare parts inventory.
