Product Description

The Filter Module functions as a passive device containing reactive components (inductors and capacitors) configured as a low-pass filter.

Key functional aspects include:

• Noise Suppression: The primary role is to attenuate (reduce) conducted electromagnetic interference ($text{EMI}$) generated by the switching action of power semiconductors within drives or power supplies.
• EMC Compliance: By limiting the high-frequency interference fed back into the main power supply, the filter module ensures that the entire system complies with strict national and international $text{EMC}$ standards (e.g., $text{EN 61800-3}$ Category $text{C}2$ or $text{C}3$).
• System Protection: By reducing noise levels, the filter module prevents operational disturbances in other sensitive electronic equipment (like communication modules, I/O modules, or central controllers) that share the same power network.
• Line Compatibility: They help to balance the currents and voltages on the supply line, often working in conjunction with line reactors.

Product Parameters

Specific parameters vary significantly based on the application (e.g., drive system, power supply, specific EMC class), but generally include:

• Rated Voltage: The nominal AC voltage of the power line (e.g., $400 text{ V}$ or $690 text{ V}$).
• Rated Current: The maximum continuous current the module can handle without overheating. This must match the current rating of the connected drive or power module.
• Power Rating: The corresponding power output (e.g., $15 text{ kW}$, $55 text{ kW}$) of the drive or power unit it is designed to support.
• EMC Category: The specific emission limits the filter helps the system meet (e.g., Category $text{C}2$ for public networks or Category $text{C}3$ for industrial networks, as defined by $text{EN 61800-3}$).
• Construction/Mounting: Enclosure type (e.g., $text{IP}20$), dimensions, and mounting method (e.g., cabinet installation, booksize format).
• Leakage Current: The amount of earth leakage current produced by the filter’s capacitors, which is a critical safety consideration.

Product Advantages

Integrating a Siemens Filter Module offers several key benefits:

• Regulatory Assurance: Guarantees that the automation system meets mandatory $text{EMC}$ requirements, avoiding potential legal or operational issues.
• System Reliability: Significantly reduces electromagnetic noise, leading to more reliable operation of all networked components, especially high-speed communication lines.
• Optimized Performance: The filter modules are precisely matched and coordinated with the specific Siemens drive or power module, ensuring maximum suppression efficiency.
• Component Longevity: Minimizes harmonic distortion and transients on the power line, which can contribute to the longer service life of other electrical equipment.
• Simplified Installation: Designed for easy integration and connection within the modular system framework (e.g., SINAMICS drive system).

Precautions and Notes

Due to their electrical nature, specific safety and operational precautions must be followed:

• High Leakage Current: Filter modules often generate high earth leakage current. Safety procedures must ensure that the installation meets requirements for permanent earthing and protective conductor cross-section to handle this current.
• Residual Voltage: Capacitors within the module may store energy. Users must observe sufficient waiting time after power-off before touching live parts to avoid electric shock.
• Correct Sizing: The filter module must be correctly sized to match the power rating and $text{EMC}$ requirements of the connected drive or power supply; using an incorrect module can lead to non-compliance or module damage.
• Cable Routing: $text{EMC}$ effectiveness depends heavily on proper installation. Input and output power cables must be separated, and shielding integrity must be maintained.
• Grounding: The mounting surface must ensure a low-impedance connection to the cabinet ground to maximize filter performance.

Product Applications

Filter Modules are used wherever high-power electronics generate significant electrical noise:

• Variable Speed Drive Systems (VSDs): Essential for frequency converters controlling motors in machine tools, pumps, fans, and conveyor systems to ensure $text{EMC}$ compliance.
• Regenerative Power Modules: Used with systems that feed energy back into the grid, ensuring the quality of the power returned is compliant.
• Industrial Power Supplies: Used with large, high-power $text{DC}$ power supplies to limit noise conducted back to the main AC line.
• Sensitive Environments: Applications in facilities (e.g., hospitals, research labs) where low electromagnetic emissions are critical to protect highly sensitive instrumentation.
• Global Export: Used when machines must be certified and shipped to regions with stringent $text{EMC}$ standards.
