Three-Phase Four-Wire Power Filter Inverter EMI Servo Purifier CW12C-3A-S Bolt-Mounted

1.Product Description

CW12C-3A-S is a three-phase four wire power filter purifier designed for complex industrial environments using bolt fastening installation. It can effectively suppress electromagnetic interference and radio frequency interference in the power grid, while purifying the harmonics generated by servo drives, frequency converters, inverters and other equipment during operation, ensuring the stable operation of precision equipment, and ensuring that the entire power system meets strict electromagnetic compatibility standards. Its sturdy bolt connection method provides high current flow capacity and high reliability connection, making it an ideal choice for improving power quality and system anti-interference ability in automated production lines, power electronics, and servo systems.

1. Applications of Frequency Converters and Inverters

Scenarios: Variable frequency drive systems for factory equipment such as fans, pumps, and compressors; grid-connected inverters and energy storage converters in photovoltaic power stations.

Function: Effectively filters high-frequency harmonics and intense electromagnetic interference generated during the switching process of VFDs/inverters, preventing interference with other sensitive equipment on the same grid. Simultaneously ensures the equipment itself meets electromagnetic compatibility standards and passes testing successfully.

2. Servo Drive System Applications

Scenario: Precision motion control fields such as CNC machine tools, industrial robots, automated assembly lines, and packaging machinery.

Function: Servo drives are highly sensitive to grid disturbances and also generate interference themselves. This purifier “cleans” the power supplied to servo drives, preventing positional errors or alarms caused by grid disturbances. It also blocks noise generated by servo drives from polluting the grid, ensuring stable operation of components like encoders and sensors within the system.

3. Industrial Automation Production Lines and Complex Electrical Environments

Scenario: Workshops with numerous mixed electrical devices (e.g., PLCs, HMIs, robots, high-power motors) in automotive manufacturing, semiconductor production lines, food processing, etc.

Function: Serves as an “electrical purification center” for entire workshops or localized areas, resolving grid pollution caused by equipment start/stop cycles and nonlinear load operations. It reduces control system malfunctions, data acquisition anomalies, and unexplained equipment tripping, enhancing overall production line reliability and efficiency.

4. Highly Sensitive Equipment Demanding Exceptional Power Quality

Scenario: Precision measuring instruments, medical imaging equipment (e.g., CT scanners), laboratory apparatus, data center server rooms.

Function: Provides “clean” power to these devices, preventing voltage spikes, harmonic distortion, and high-frequency noise from compromising measurement accuracy, imaging quality, or data processing precision.

In summary, the core application value of the CW12C-3A-S lies in:

Within complex industrial power grids, it acts as a “guardian.” Through its powerful filtering and purification capabilities, it ensures stable, interference-free operation of primary disturbance sources like inverters and servo systems while protecting the grid and other sensitive equipment from contamination. Its bolt-on installation feature guarantees connection reliability and long-term stability in high-current applications.
