Product Description

A SIEMENS Filter Module is an essential auxiliary component primarily used in industrial power electronics systems, such as drive technology (e.g., inverters and power modules). Its main function is to limit and suppress Conducted Interference (Electromagnetic Interference – EMI) generated by the switching operations of the drive components (like Power Modules).

These modules are typically installed on the line (input) side of the Power or Line Modules. They act as a sophisticated passive filter network to ensure that the electromagnetic emissions of the system comply with required international and local Electromagnetic Compatibility (EMC) standards and regulations (e.g., categories like C2 for environment 1 or C3 for environment 2, based on the standard EN 61800-3).

Product Parameters

General technical parameters for Siemens Filter Modules typically include:

Product Advantages

1. EMC Compliance: The primary advantage is ensuring that the entire system complies with stringent international and national EMC standards, preventing undesirable interaction with other sensitive electronic equipment.
2. Interference Suppression: They effectively reduce conducted electrical noise and harmonics generated by the power switching, leading to a “cleaner” electrical supply.
3. System Reliability: By mitigating electromagnetic noise, filter modules help prevent potential disruptions or damage to sensitive control electronics and communication systems, thereby improving overall system reliability.
4. Integration: Designed for seamless electrical and mechanical integration with corresponding Siemens drive systems (e.g., SINAMICS series).
5. Enhanced Performance: Allows for operation in environments where low interference levels are mandatory (e.g., residential or mixed environments).

Precautions

1. Safe Handling (ESD): Electronic components within the module can be sensitive to Electrostatic Discharge (ESD). Always observe ESD precautions (e.g., grounding straps, conductive surfaces) when handling the product.
2. Electrical Safety (Voltage/Discharge): Even after the power supply is switched off, dangerous residual voltages may remain in the system’s intermediate DC link or on the filter components. Observe the specified discharge time on warning labels and verify a zero-voltage state before touching any connections.
3. Thermal Management: Filter modules, especially line filters, can generate heat. Ensure that the permissible ambient temperature is adhered to and allow for proper heat dissipation to avoid the risk of burns or component damage.
4. Grounding: Proper and robust protective conductor (PE) connection and grounding of cable shields are crucial for both safety (electric shock) and effective EMC performance.
5. Installation Environment: The module must only be used for the applications described in the official Siemens technical documentation, and compliance with all installation, connection, and operating conditions is mandatory.

Product Applications

Siemens Filter Modules are primarily used in applications where frequency converters and power supplies generate high-frequency interference. Key application areas include:

1. Industrial Drive Systems: Used with AC drives (like SINAMICS) in machine tools, pumps, fans, compressors, and general machinery to ensure compliance with EMC regulations.
2. Automation Technology: Integrated into complex automation and control cabinets where multiple electronic devices operate in close proximity and communication integrity is paramount.
3. Sensitive Environments: Necessary when the system is installed in environment 1 (public or residential networks, C2 category) where lower levels of conducted emissions are required.
4. Power Quality: Used in systems to improve overall power quality and reduce harmonic distortion on the main electrical supply.
5. Motor and Motion Control: Essential in high-performance motion control applications to protect control signals from electrical noise.
