F9GT-40FMB MITSUBISHI Filter Modules

Product  Description：

Mitsubishi Electric Filter Modules are specialized electromagnetic compatibility (EMC) and noise suppression components designed to protect sensitive control electronics and improve power quality. These modules are primarily used in conjunction with variable frequency drives (VFDs), servo amplifiers, and power supplies to mitigate the effects of high-frequency electrical noise and harmonic distortion generated by high-speed switching transistors.

Product Parameters

The technical profile of a Mitsubishi Filter Module is defined by its attenuation capabilities and electrical ratings:

• Rated Current: Ranges from small capacity (5A) for control circuits to high capacity (up to 1000A or more) for large industrial inverter systems.

• Rated Voltage: Supports standard industrial voltages including 200V-240V AC and 380V-480V AC, available in both single-phase and three-phase configurations.

• Frequency Range: Designed to suppress noise in the radio frequency range, typically focusing on the 150kHz to 30MHz band.

• Leakage Current: Specifically engineered to keep leakage current within safe limits (often below 30mA or 100mA) to prevent nuisance tripping of Earth Leakage Circuit Breakers (ELCB).

• Insertion Loss: Provides high attenuation levels, often exceeding 40dB to 60dB in critical frequency ranges to ensure compliance with global EMC standards.

• Terminal Type: Features screw terminals or high-current busbar connections for secure, low-resistance electrical contact.

Product Advantages

Mitsubishi Filter Modules offer significant performance benefits for modern automated environments:

• EMC Compliance: Enables machinery to meet strict international electromagnetic compatibility standards (such as CE, UL, and high-level industrial EMC directives) by reducing conducted emissions.

• System Longevity: By smoothing out voltage spikes and reducing high-frequency harmonics, these filters protect motor windings and sensitive semiconductor components from premature insulation breakdown.

• Signal Integrity: Prevents electrical "noise" from interfering with nearby low-voltage signals, such as sensor feedback, communication lines, and analog control loops.

• Optimized Thermal Design: Built with high-quality magnetic cores and low-loss capacitors to ensure that the filter remains cool even during continuous full-load operation.

• Space-Saving Form Factor: Many Mitsubishi filters are designed with a "footprint" shape, allowing the drive or inverter to be mounted directly on top of the filter to save cabinet space.

Product Applications

These modules are essential in environments where electrical precision and noise control are paramount:

• Variable Frequency Drives (VFDs): Installed on the input side of inverters to prevent noise from feeding back into the factory power grid.

• Servo Systems: Used in high-precision motion control for robotics and CNC machines to ensure that switching noise does not corrupt encoder feedback.

• Medical Equipment: Ensuring that power-intensive imaging or diagnostic tools do not interfere with sensitive monitoring electronics.

• Telecommunications: Protecting data centers and communication hubs from electrical interference generated by large-scale cooling and power backup systems.

• Cleanroom Environments: Maintaining low electromagnetic interference levels to prevent disruption of delicate semiconductor manufacturing processes.

Important Precautions

To ensure effective noise suppression and safety, the following guidelines are critical:

• Correct Grounding: The filter's metal housing must be securely bonded to the control panel's common ground plate with a short, thick wire or conductive strap to provide a low-impedance path for noise.

• Wiring Separation: Never bundle the input (line) cables and output (load) cables of the filter together. This "cross-talk" can allow noise to bypass the filter entirely, rendering it ineffective.

• Proximity to Source: For maximum effectiveness, the filter should be installed as close as possible to the noise-generating device (such as the inverter or servo amplifier).

• Residual Charge: High-capacity capacitors inside the filter can store electricity after power is disconnected. Always wait at least five minutes before touching terminals to avoid electric shock.

• Leakage Current Consideration: Be aware that adding multiple filters to a single system increases total leakage current. Ensure that your upstream ground-fault protection devices are rated accordingly to avoid accidental trips.
