R16CPU MITSUBISHI Filter Modules

Product  Description：

Mitsubishi Electric Filter Modules are specialized electromagnetic compatibility (EMC) and noise suppression components designed to work in tandem with power converters, inverters, and servo drives. These modules are engineered to mitigate the high-frequency electromagnetic interference (EMI) and radio frequency interference (RFI) generated by high-speed switching semiconductors, ensuring compliance with international EMC standards.

Product Parameters

The performance of a Mitsubishi Filter Module is defined by its ability to attenuate electrical noise while maintaining high power efficiency:

• Rated Current: Ranges from small-scale 5A units for micro-drives to high-capacity versions exceeding 600A for industrial power systems.

• Rated Voltage: Typically supports three-phase AC 200V to 480V or DC link voltages up to 800V, depending on the specific series.

• Attenuation Frequency: Optimized for the 150 kHz to 30 MHz range, which is the critical spectrum for conducted emissions testing.

• Leakage Current: Low-leakage designs (often below 5mA to 10mA) to prevent nuisance tripping of Earth Leakage Circuit Breakers (ELCB).

• Insertion Loss: High insertion loss characteristics (measured in decibels) across a wide frequency band to effectively dampen common-mode and differential-mode noise.

• Case Material: High-grade metallic or resin-filled enclosures designed for maximum thermal conductivity and shielding effectiveness.

Product Advantages

Mitsubishi Filter Modules offer several engineering benefits for complex electrical environments:

• Seamless System Integration: Specifically tuned to the switching frequencies of Mitsubishi’s MELSERVO and FR-series inverters, ensuring maximum noise reduction without compatibility issues.

• Enhanced Equipment Reliability: By filtering out harmonic distortions and voltage spikes, these modules protect sensitive sensors and communication lines from malfunction or data corruption.

• Global Compliance: Facilitates the certification of machinery for CE, UL, and localized EMC regulations, reducing the need for extensive external shielding.

• Thermal Efficiency: Designed with low-loss magnetic cores and high-conductivity windings to minimize heat generation during continuous high-load operation.

• Compact Footprint: High-density winding techniques allow for a significant reduction in size compared to generic passive filters, saving valuable space in control cabinets.

Product Applications

These modules are indispensable in environments where electrical cleanliness is a priority:

• Precision Manufacturing: Used in CNC machines and robotic cells to prevent motor noise from interfering with delicate feedback encoders and control logic.

• Medical Facilities: Employed in hospital power systems to ensure that high-power HVAC or elevator inverters do not disrupt sensitive diagnostic equipment.

• Data Centers: Integrated into cooling system inverters to maintain the integrity of high-speed data transmission lines.

• Renewable Energy Stations: Filtering the output of solar and wind inverters before the power is fed into the public utility grid.

• Building Automation: Reducing audible noise and electrical interference in commercial elevator systems and large-scale air handling units.

Important Precautions

To achieve effective noise suppression, the following installation and handling guidelines must be observed:

• Proximity to Source: The filter module should be installed as close as possible to the noise source (the inverter) to prevent the cables between them from acting as antennas.

• Grounding Connection: A low-impedance ground connection is vital. Use thick, short grounding straps or wires rather than long, thin cables to ensure effective common-mode noise diversion.

• Input and Output Separation: Never bundle or route the filter's input (line) cables and output (load) cables together. Crossing these lines will cause "noise re-coupling," effectively bypassing the filter.

• Cable Shielding: For maximum effectiveness, use shielded cables for the output side and ensure the shield is properly bonded to the metal backplate of the cabinet.

• Voltage Discharge: Like inverters, filter modules contain internal capacitors. Wait for the specified discharge time (usually several minutes) after disconnecting power before touching the terminals to avoid electrical shock.
