SGDR-COBCA01AB YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are specialized electrical components designed to mitigate electromagnetic interference (EMI), radio frequency interference (RFI), and harmonic distortions generated by high-frequency switching power electronics. Primarily paired with Yaskawa’s AC drives (VFDs) and servo systems, these modules ensure compliance with international EMC directives and safeguard neighboring sensitive control equipment from electrical noise transmitted through power lines.

Product Parameters

The technical parameters of Yaskawa Filter Modules vary by application, ranging from line filters to regenerative noise suppression units:

• Rated Voltage: Supports single-phase 200V AC up to three-phase 400V–480V AC power systems.

• Rated Current: Designed to accommodate various motor drive capacities, with models ranging from 5A for small servo packs to over 400A for heavy industrial drives.

• Insertion Loss: Provides excellent noise attenuation, typically reducing EMI/RFI noise emissions by 20 decibels to 40 decibels across a broad frequency spectrum (150kHz to 30MHz).

• Leakage Current: Engineered with low-capacitance topologies to keep ground leakage current within safe thresholds, typically under 3.5mA or up to 30mA for industrial-grade models.

• Ambient Operating Temperature: Rated for reliable performance between -10°C and 50°C without derating.

• Insulation Resistance: Offers robust safety insulation, commonly rated at 500V DC with a minimum resistance of 100 Megohms.

Product Advantages

Yaskawa Filter Modules provide critical electrical stabilization and compliance benefits for automated machinery:

• Strict Compliance: Ensures that power conversion installations easily meet strict global standards such as CE, UL, and EN 61800-3 electromagnetic compatibility requirements.

• Protection for Sensitive Electronics: By filtering out high-frequency noise spikes, these modules prevent logic errors and erratic behavior in nearby PLCs, sensors, and communication networks.

• Drive Lifespan Extension: Reduces common-mode currents and voltage reflection (dv/dt effects), which protects motor wind insulation and prevents premature bearing pitting.

• Compact Footprint: Many Yaskawa filter variants feature a "footprint" or "bookcase" design, allowing them to be mounted directly underneath or adjacent to the drive to maximize panel space.

• Low Heat Generation: Built with high-quality magnetic cores and low-loss capacitors, minimizing power dissipation and thermal load inside the control enclosure.

Product Applications

These modules are integrated into systems where power quality and signal integrity are paramount:

• Precision Robotics: Suppressing servo-generated noise to maintain clean feedback signals for high-resolution encoders.

• Facility Infrastructure: Installed alongside HVAC drives in hospitals, commercial buildings, and laboratories to prevent harmonic noise from disrupting sensitive diagnostic equipment.

• Machine Tooling: Used in high-speed CNC milling and turning centers to protect weak analog control signals from the high-power spindle drive.

• Semiconductor Cleanrooms: Safeguarding high-purity environment sensors and automated wafer handling systems from power line disturbances.

• Printing and Packaging: Protecting high-speed communication networks from the EMI produced by multiple synchronized servo drives.

Important Precautions

To guarantee effective noise suppression and prevent safety hazards, installation must follow these guidelines:

• Short Wiring Lengths: Keep the cable connecting the filter module to the input of the drive as short as possible. Long wires act as antennas and can re-radiate electromagnetic noise.

• Proper Grounding: The filter module must have a solid, low-impedance electrical connection to the cabinet backplane. Scrape away paint from the mounting surface to ensure clean metal-to-metal contact.

• Separation of Input and Output Lines: Never route the input lines (clean power) and output lines (noisy power) of the filter module in the same conduit or bundle. Doing so can cause cross-talk, bypassing the filter entirely.

• Leakage Current Warning: Because filters utilize capacitors connected to ground, they naturally generate leakage current. Ensure the main system enclosure is securely grounded to prevent electric shock hazards.

• Voltage Rating Verification: Double-check that the line voltage matches the filter's specifications. Applying a voltage higher than the rated limit can puncture the internal capacitors and cause module failure or smoke.
