Product Description

A SIEMENS Filter Module is an electrical component designed to suppress electromagnetic interference (EMI) and condition power signals within a system. These modules are specifically engineered to ensure compliance with electromagnetic compatibility (EMC) standards by attenuating conducted noise both into and out of electronic equipment. They typically contain passive components such as inductors and capacitors, forming a low-pass filter that effectively blocks high-frequency noise while allowing the low-frequency operating current to pass through unimpeded. This is crucial for maintaining the reliable operation of sensitive devices and preventing equipment from polluting the power supply network.

Product Specifications

Product Advantages

• EMC Compliance: Helps systems achieve necessary international and regional EMC certifications, reducing the risk of regulatory issues.

• System Reliability: Protects sensitive electronic components from voltage transients and high-frequency noise, leading to more stable and reliable operation.

• Noise Reduction: Significantly reduces conducted emissions from the equipment, preventing interference with other devices on the same power line.

• Component Protection: Extends the lifespan of electrical components by providing clean, stable power.

• Robust Design: Built with high-quality components for long service life, even in harsh industrial environments.

Precautions for Use

• Grounding Connection: A low-impedance and secure connection to earth (ground) is absolutely essential for the filter to function correctly. The filter’s performance is directly dependent on the quality of its ground connection.

• Current Rating: Never exceed the module’s specified rated current, as this can lead to overheating and potential component failure.

• Installation Location: Install the filter as close as possible to the point where the power line enters the equipment enclosure (the source of the noise) for maximum effectiveness.

• Cabling Separation: Keep the input (dirty) and output (clean) wiring physically separated to prevent noise from coupling back across the filter.

• Leakage Current Awareness: Be mindful of the filter’s leakage current, which can be significant in larger filters. Ensure protective earthing measures comply with safety regulations.

Product Applications

SIEMENS Filter Modules are widely used in applications where electromagnetic noise is a concern or where strict EMC standards must be met:

• Industrial Drives and Motor Control: Used with Variable Frequency Drives (VFDs) and inverters to suppress the high-frequency switching noise generated by power electronics.

• Power Supplies: Integrated into switching mode power supplies to clean the incoming line and suppress generated noise.

• Automation and Control Systems: Protects Programmable Logic Controllers (PLCs) and sensitive control electronics from industrial noise.

• Medical Equipment: Essential for maintaining signal integrity and safety in environments with stringent noise requirements.

• Data Processing Equipment: Installed in IT hardware and servers to ensure stable operation and meet conducted emission standards.
