EPC38790FDB3 EATON Filter Modules

Product  Description：

EATON offers various types of filter modules, including surge suppressors, EMI/RFI filters, and line filters, tailored for different applications such as protecting automation equipment, improving power supply quality, or meeting specific machine safety requirements. They typically use passive electronic components like capacitors, inductors, and resistors arranged in specific configurations to attenuate unwanted frequencies or divert transient voltages.

Key Functions

• Noise Attenuation: Significantly reduces conducted and radiated electromagnetic noise (EMI/RFI) on power and signal lines.

• Surge Protection: Protects sensitive electronics from transient voltage spikes (surges) caused by lightning or switching operations.

• EMC Compliance: Helps machinery and control panels meet stringent international electromagnetic compatibility directives and standards.

• System Reliability: Prevents erratic operation, data corruption, and premature failure of sensitive electronic devices like PLCs, drives, and sensors.

Product Parameters (Typical)

Parameters depend heavily on the specific filter module type (e.g., single-phase, three-phase, signal line filter).

• Rated Voltage (V): The maximum continuous operating voltage (e.g., 120 VAC, 230 VAC, 480 VAC, 600 VAC).

• Rated Current (A): The maximum continuous current the filter can safely handle (e.g., 3 A to 200 A+).

• Insertion Loss (dB): The measure of the filter's effectiveness in attenuating noise at specific frequencies (e.g., typically 10 kHz to 30 MHz).

• Filter Type: Single-stage, two-stage, or multi-stage; delta or star connection (for three-phase).

• Frequency Range (Hz): The intended operating line frequency (e.g., 50/60 Hz).

• Surge Rating: For surge suppression filters, this includes the maximum discharge current (kA) and clamping voltage.

• Terminal Type: Screw terminals, studs, or wire leads.

• Approvals: Compliance with standards such as UL, CSA, CE, and RoHS.

Product Advantages

• Superior Protection: Provides robust defense against electrical disturbances, extending the lifespan and ensuring the stable operation of control components and electronic loads.

• Regulatory Compliance: Facilitates compliance with international EMC standards, which is often mandatory for market access.

• Optimized Performance: Improves the performance of equipment like Variable Frequency Drives (VFDs) by suppressing harmful transients and harmonics.

• Broad Portfolio: EATON offers a wide selection of filters to match specific power requirements, current ratings, and application environments.

• Easy Integration: Designed for straightforward panel mounting and wiring into existing electrical enclosures and control panels.

Precautions

• Grounding: Proper, low-impedance grounding is absolutely essential for the filter module to function effectively and safely. The filter case must be securely connected to the panel's ground plane.

• Current Rating: Never exceed the specified continuous rated current of the filter, as this can lead to overheating and failure.

• Isolation: Input and output wiring should be physically separated and shielded where possible to prevent noise bypass or coupling.

• Voltage Selection: Ensure the filter's rated voltage is appropriate for the line voltage of the application.

• Load Matching: The filter must be installed as close as possible to the source of the noise or the protected equipment, depending on the application.

Product Applications

EATON filter modules are critical components used wherever power quality and electromagnetic interference are concerns, across various industries.

• Industrial Automation and Control Panels: Protecting PLCs, HMIs, servo drives, and industrial PCs from line noise and surges.

• Variable Frequency Drives (VFDs): Used as line side filters to prevent drive-generated noise from propagating back into the power system, or as load side filters to protect motor windings.

• Medical Equipment: Ensuring the clean and reliable power supply required for sensitive diagnostic and life-support devices.

• Telecommunications: Filtering power lines to maintain high data integrity and reliability in communication systems.

• Power Supplies: Installed at the input of sensitive power supplies to meet demanding EMC requirements.

• Machine Tools: Protecting the complex electronic controls of CNC machines and robotics.
