The CW3-3A-T Series Plug-in Single-Phase AC Power Filter is a highly efficient power purification device specifically designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). This series covers multiple rated current levels including 3A, 6A, 10A, and 20A, featuring a compact plug-in structure for easy installation and integration. It effectively filters high-frequency noise conducted between the power grid and electronic equipment, ensuring sensitive devices—such as communication systems, industrial controllers, medical instruments, and laboratory power supplies—receive clean, stable power. Simultaneously, it helps equipment meet stringent electromagnetic compatibility (EMC) regulations, enhancing overall system reliability and interference resistance.
1. Industrial Robot Control Cabinet
Installed at the power inlet of the control cabinet, it supplies power to servo drives and PLCs. It effectively suppresses high-frequency noise generated during motor operation, preventing interference with sensitive controllers and ensuring precise, error-free robot movements.
2. Medical Monitoring Equipment
Serves as an internal power module for patient monitors, electrocardiographs, and similar devices. Filters out interference from grid fluctuations to ensure clear and stable acquisition and display of vital signs, preventing false alarms.
3. Communication Base Station Power Supply
Installed at the input end of the base station power module. Blocks sudden noise surges in the grid that could disrupt signal transmission while preventing noise pollution from the base station's power components from entering the grid, thereby enhancing communication quality.
4. Laboratory Precision Test Instruments
Supplies power to high-precision oscilloscopes or spectrum analyzers. Purifies background noise from the power grid, providing instruments with a “clean” power environment to ensure measurement data accuracy and reliability.
5. Electric Vehicle Charging Stations
Used in the power section of AC charging station control boards. Suppresses electromagnetic interference generated by switching power supply circuits, ensuring stable and reliable charging operations while aiding the entire unit in passing electromagnetic compatibility (EMC) certification.
