SGMSH-20DCA6F-O YASKAWA Filter Modules

Product  Description：

Yaskawa Filter Modules are essential peripheral components designed to work in conjunction with AC drives (VFDs) and servo amplifiers. These modules are specifically engineered to mitigate electromagnetic interference (EMI) and high-frequency noise generated by the high-speed switching of power semiconductors. By purifying the electrical signal both on the input (line) side and the output (load) side, these filters ensure that the automation system complies with international EMC standards and protects sensitive electronic equipment from harmonic distortion.

Product Parameters

The technical profile of Yaskawa Filter Modules focuses on electrical suppression and current handling capabilities:

• Rated Voltage: Available for single-phase 200V-240V and three-phase 200V-480V AC systems, with specialized versions for 600V class industrial grids.

• Current Ratings: Ranges from low-current versions (5A-10A) for small servo units to high-capacity models exceeding 1000A for large industrial inverters.

• Attenuation Frequency: Optimized to suppress noise across a broad spectrum, typically from 150kHz to 30MHz, covering the most common EMI bands.

• Leakage Current: Designed with low-leakage capacitor configurations to prevent nuisance tripping of residual current devices (RCDs) and ground fault circuit interrupters (GFCIs).

• Insertion Loss: High attenuation performance, often exceeding 60dB in the critical interference frequency ranges.

• Enclosure Rating: Usually offered in IP00 for cabinet mounting or IP20 for touch-safe operation, utilizing robust metal housings for superior shielding.

Product Advantages

Yaskawa Filter Modules provide a critical layer of protection and compliance for industrial networks:

• Global EMC Compliance: Enables machinery to meet strict CE, UL, and high-level electromagnetic compatibility standards required for global export.

• Protection of Sensitive Electronics: Prevents high-frequency noise from traveling back into the power grid, which could otherwise cause malfunctions in nearby sensors, PLCs, or medical equipment.

• Motor Longevity: Output-side filters (such as dV/dt filters or sine wave filters) reduce the voltage stress on motor windings and bearings, significantly extending the life of the motor.

• Reduction of Heat and Vibration: By smoothing the current waveform and reducing harmonics, these filters help decrease audible motor noise and excess heat generated by eddy currents.

• Seamless Mechanical Integration: Many Yaskawa filters are designed with a "footprint" shape, allowing the inverter to be mounted directly on top of the filter to save precious space inside the control panel.

Product Applications

These modules are deployed in environments where electrical "cleanliness" and system reliability are paramount:

• Precision Manufacturing: Essential in semiconductor and laboratory environments where even minor electrical noise can interfere with sensitive measurement instruments.

• Long-Distance Cable Runs: Used when the distance between the drive and the motor exceeds 20-50 meters to counteract the "reflected wave" phenomenon that can damage motor insulation.

• Public and Commercial Buildings: Ensuring that HVAC systems and elevators do not interfere with building telecommunications, Wi-Fi networks, or office equipment.

• Renewable Energy Systems: Filtering the output of power converters in solar and wind applications to maintain power quality at the grid connection point.

• High-Speed Automation: Stabilizing the feedback signals from encoders and sensors in high-speed bottling and packaging lines by maintaining a quiet electrical environment.

Important Precautions

To ensure the effectiveness of the filter and the safety of the system, the following installation rules must be followed:

• Proper Grounding: The filter housing must have a low-impedance connection to the system's common ground. Remove any paint from the mounting plate to ensure a "metal-to-metal" contact for effective noise shunting.

• Wiring Separation: Never bundle the input (clean) wires and output (noisy) wires of the filter together. Cross-talk between these lines will bypass the filter entirely and render it ineffective.

• Short Cable Lengths: The distance between the filter and the drive should be kept as short as possible. Long leads act as antennas and can re-radiate the noise that the filter is trying to suppress.

• Thermal Considerations: Filters can become hot during continuous high-load operation. Ensure there is adequate space for airflow around the module and do not mount it near heat-sensitive plastic components.

• Correct Selection: Always match the filter’s rated current to the maximum input current of the drive, not the motor. An undersized filter will saturate and overheat, leading to potential fire hazards or system failure.
