Supply Continuity Notice – Alternative EMC Filters

Due to ongoing challenges in the global supply chain, we are introducing alternative EMC filters from an additional qualified supplier into our product offering. This proactive step allows us to secure product availability and maintain the high reliability standards our customers expect.

The proposed alternative filters have been carefully selected to align with our technical and quality requirements. They are intended to be compatible with existing systems in terms of performance and integration, ensuring minimal impact on your applications. Nevertheless, we recommend verifying suitability based on your specific system requirements.

Please note that, while these filters are functionally suitable and meet our rigorous evaluation criteria, certain specification details may vary slightly. We encourage you to review the technical document provided for more information on these differences.

The table below presents alternative products to the existing EMC filters lineup.

Important Notice about EMC Compliance

Please note that while the alternative EMC filters introduced in this document have been selected and evaluated to meet high technical standards, we strongly recommend that end users perform individual EMC compliance assessments for their specific applications.

Final EMC performance is influenced by multiple factors beyond the filter itself. These include, but are not limited to:

• Correct grounding and bonding practices throughout the installation

• Proper routing and shielding of power and signal cables

• The switching frequency of the drive's IGBTs (PWM frequency)

• Cable lengths between the drive, filter, and motor

• Installation layout and enclosure design

• Presence and arrangement of other electronic equipment nearby

• Load type and operating conditions

• Power line impedance and supply quality

• Use of unshielded cables or improper terminations

It is essential to understand that Variable Frequency Drives (VFDs) are complex electronic systems whose electromagnetic emission behavior is determined by the complete setup. Even minor deviations from recommended installation guidelines can lead to increased EMC emissions or reduced immunity.

Therefore, to ensure reliable and compliant operation, we recommend adhering strictly to EMC best practices and validating system performance through appropriate on-site measurements, particularly in sensitive or regulated environments.
