CW3-3A-T Plug-In-Single Phase AC CW3-6A/10A/20A-T Power Filters EMI
Power Supply
1.Product Description
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.
