Product Description

A Filter Module, often referred to as a Line Filter or RFI (Radio Frequency Interference) Filter, is a passive electrical component installed on the power supply line (input) of electrical equipment. Its purpose is twofold:

1. Protect the Grid/Mains: To attenuate (reduce) high-frequency conducted interference (noise) generated by devices like variable speed drives and switched-mode power supplies, preventing this noise from polluting the electrical network.

2. Protect the Equipment: To shield the connected industrial equipment (e.g., drive, PLC power supply) from external noise present on the mains supply.

These filters typically consist of passive components such as inductors (chokes) and capacitors arranged in a specific circuit configuration ($LC$ filter) to suppress both common-mode and differential-mode noise.

Product Parameters

The parameters are specific to the electrical capacity and filtering characteristics:

Product Advantages

• EMC Compliance: Ensures the industrial installation meets mandatory international (e.g., $CE$) and regional electromagnetic compatibility standards, avoiding operational conflicts and regulatory issues.

• System Reliability: By mitigating noise, the filter protects sensitive electronics (PLCs, HMI, communication modules) from voltage spikes and electromagnetic disturbances, enhancing overall system reliability and longevity.

• Reduced Downtime: Prevents communication errors and sporadic malfunctions often caused by high-frequency noise interference, thereby reducing costly, difficult-to-diagnose downtime.

• Optimized Drive Performance: Necessary for many variable frequency drive applications to allow for longer motor cable lengths while still meeting EMC limits.

• Simplified Integration: Designed to be dimensionally and electrically compatible with SIEMENS drive systems (e.g., SINAMICS series), making selection and installation straightforward.

Important Considerations

• Correct Sizing: The filter’s rated current must be equal to or greater than the maximum input current of the connected load (e.g., the drive module). Undersizing will lead to overheating and failure.

• Installation Proximity: The filter must be installed as close as possible to the device it is protecting, and the wiring between the filter and the device should be kept short and unshielded to maximize effectiveness.

• Grounding: Proper, low-impedance connection to the central grounding point of the control cabinet is absolutely critical for the filter’s performance, as common-mode noise suppression relies on this connection.

• Safety: Line filters contain capacitors that can hold a charge even after power is removed. Always observe safe handling procedures and check documentation for required discharge times.

Typical Product Applications

Filter Modules are primarily used wherever high-frequency noise is generated or is a concern:

• Variable Speed Drive (VFD) Systems: Essential components for almost all $AC$ and $DC$ drive installations to suppress the high-frequency switching noise generated by the drive’s power electronics.

• Machine Tools: Protecting the sensitive electronics of $CNC$ controls and servo systems from electrical disturbances on the mains.

• Power Supply Protection: Installing a filter on the incoming line of a large control cabinet to protect the central power supply units from upstream grid noise.

• Automated Production Lines: Ensuring reliable communication and operation of interconnected PLCs and sensors by cleaning the main power distribution.
