VMV21L3TWUNV1 EATON Filter Modules

Product  Description：

EATON manufactures a variety of filter modules, ranging from power line filters for equipment protection to specialized signal filters for control systems. These modules integrate various electronic components (capacitors, inductors, resistors) to form filtering networks that attenuate unwanted noise and transients entering or leaving a system. By suppressing noise, these modules help systems comply with electromagnetic compatibility (EMC) standards and improve overall operational uptime.

Product Parameters (Typical)

Parameters vary significantly depending on whether the module is a power line filter (EMI/RFI) or a signal filter.

• For Power Line Filters (EMI/RFI):

  • Rated Voltage: The maximum continuous voltage (e.g., 120V AC, 250V AC, 480V AC).

  • Rated Current: The maximum continuous current the filter can handle (e.g., 1A to 2000A).

  • Frequency: Operating frequency (e.g., 50/60 Hz).

  • Attenuation: The level of noise reduction achieved, typically specified in dB across a frequency range (e.g., 150 kHz to 30 MHz).

  • Filter Stages: Single-stage, two-stage, or multi-stage filtering.

  • Connection Type: Terminal block, bolt, or stud connections.

  • Leakage Current: The small amount of current that flows to ground, critical for medical applications.

• For Signal/Control System Filters:

  • Number of Lines: The number of signal conductors filtered (e.g., 1, 2, 4 pairs).

  • Cut-off Frequency: The point at which filtering begins (e.g., for low-pass filters).

  • Data Rate: Maximum data rate supported (important for communication line filters).

  • Impedance: Designed to match the characteristic impedance of the line (e.g., 50 Ohm, 100 Ohm).

Product Advantages

• High Reliability: Ensures the continuous and accurate operation of sensitive electronic devices by providing clean power and signals.

• EMC Compliance: Helps industrial equipment and machinery meet stringent international electromagnetic compatibility standards (e.g., CE, UL, CSA, MIL-STD).

• Equipment Protection: Protects expensive control systems, PLCs, VFDs, and power supplies from damaging voltage spikes and electrical noise.

• Improved System Performance: Reduces data errors, false tripping, and communication failures caused by interference.

• Versatile Range: EATON offers a broad portfolio catering to single-phase, three-phase, DC, and signal line applications.

• Ease of Installation: Often designed in compact formats for DIN rail mounting or bulkhead installation, simplifying integration into control cabinets.

Precautions

• Grounding: Proper grounding is absolutely essential for the filter to work effectively. The filter housing must be connected to a low-impedance ground plane.

• Current Rating: Never exceed the rated current of the filter module; overloading can cause overheating and failure.

• Voltage Rating: Ensure the line voltage is within the specified voltage range of the filter.

• Installation Location: Filters should be installed as close as possible to the protected equipment or at the point of cable entry into the enclosure to maximize effectiveness.

• Leakage Current: When using power filters, be aware of the leakage current, especially in residential, medical, or high-sensitivity ground fault areas, and choose an appropriate model.

• Temperature: Operate within the specified ambient temperature range to maintain performance and lifespan.

Product Applications

EATON filter modules are utilized wherever electrical noise poses a threat to system performance or compliance.

• Industrial Automation: Protecting PLCs, HMIs, servo drives, and industrial PCs from noise generated by motor controls (VFDs) and heavy machinery.

• Power Quality: Suppressing line-conducted noise in power distribution systems and protecting mission-critical equipment like servers and data centers.

• Medical Equipment: Ensuring low leakage current and high noise immunity in sensitive medical devices (e.g., MRI, X-ray machines).

• Renewable Energy: Filtering power inverters and converters used in solar and wind power generation systems.

• Telecommunications: Protecting communication equipment and infrastructure from line noise and surges.

• Military and Aerospace: Providing robust filtering solutions for demanding, high-reliability applications.
