Schneider Electric VSDs, often branded as Altivar, are electronic devices that control the speed of electric motors.By adjusting the frequency of the power supplied to the motor, VSDs can precisely regulate motor speed,
torque, and power. This provides numerous benefits in industrial automation and energy efficiency.
Key Features and Benefits
Energy Efficiency:VSDs significantly reduce energy consumption by matching motor speed to the load, eliminating the need for constant full-speed operation.
Precise Speed Control: Achieve accurate speed control for a wide range of applications, from simple pumps to complex conveyor systems.
Torque Control: VSDs enable precise torque control, improving process control and product quality.
Soft Start and Stop: Reduce mechanical stress on equipment and extend its lifespan by providing smooth start and stop operations.
Increased Motor Protection: Built-in protection features safeguard the motor from overloads, under-voltage, and other potential damage.
Enhanced Process Control: VSDs offer advanced control features for optimizing process efficiency and productivity.
Remote Monitoring and Control: Integrate VSDs into industrial automation systems for remote monitoring and control.
Typical Product Parameters
VSD parameters can vary widely depending on the specific model and application. Common parameters include:
Power Rating: The maximum output power of the VSD.
Voltage: The input voltage required for operation.
Frequency Range: The range of output frequencies that can be generated.
Motor Type: Compatibility with different types of motors (e.g., induction, synchronous).
Control Modes: Available control modes (e.g., V/f, vector).
Communication Protocols: Supported communication protocols for integration with other devices.
Applications
Schneider Electric VSDs are used in a wide range of industries and applications, including:
Pumping Systems: Control flow rates in water and wastewater treatment, HVAC systems, and industrial processes.
