Frequently Asked Questions
How do I install the EAC-06-472 EMI filter?
Installing the EAC-06-472 EMI filter: Mounting: Use M4 threaded studs for panel mounting; Mount to metal chassis for grounding; Ensure good electrical contact; Torque nuts to 1.5-2.0 Nm. Wiring: Connect input (LINE/NEUTRAL) to power source; Connect output (LOAD) to power supply input; Use 6.3mm quick connect terminals; Keep wiring as short as possible. Grounding: Connect ground terminal to chassis ground; Use short, wide ground wire; Ensure low impedance ground path. Layout: Mount close to power supply input; Separate input and output wiring; Keep filtered wiring away from unfiltered. Testing: Verify continuity after installation; Check ground connection; Measure leakage current if required. Contact our FAE team for installation guidance.
Mount to chassis with M4 studs. Connect input to source, output to supply. Contact us for installation.
What attenuation does the EAC-06-472 provide?
The EAC-06-472 provides frequency-dependent attenuation: Typical attenuation: 40dB at 1MHz (typical measurement point); Frequency range: 150kHz to 30MHz (conducted emissions range); Common mode: 35-50dB depending on frequency; Differential mode: 30-45dB depending on frequency. Attenuation curves: Highest attenuation in 1-10MHz range; Lower attenuation at band edges; Varies with source and load impedance. For EMC compliance: 40dB typically sufficient for Class B; May need additional filtering for severe cases; System layout affects actual performance. Measurement: Use spectrum analyzer with LISN; Measure common mode and differential mode separately; Compare to EMC limits with margin. Contact our FAE team for attenuation requirements.
40dB typical attenuation. Sufficient for most Class B applications. Contact us for requirements.
Can the EAC-06-472 be used with non-Cosel power supplies?
The EAC-06-472 can be used with other power supplies with considerations: Current rating: 6A rating must match supply input current; Check supply datasheet for input current; Include margin for inrush current. Voltage rating: 250VAC rating must exceed supply input; Suitable for universal input supplies; Check for DC applications (different filter needed). Attenuation: 40dB may or may not be sufficient; Depends on supply noise characteristics; May need higher attenuation filter. Compatibility: Filter impedance affects performance; Best matched to Cosel supply designs; May need different filter for other brands. Recommendations: Check supply manufacturer recommendations; Measure conducted emissions with filter; Verify compliance with applicable standards. Cosel filters optimized for Cosel supplies. Contact our FAE team for compatibility assessment.

What is the leakage current of the EAC-06-472?
The EAC-06-472 has low leakage current: Leakage current: <0.5mA at 250VAC, 60Hz; Measured line to ground and neutral to ground; Includes Y capacitor leakage. Safety standards: IEC limits: 3.5mA for portable, 5mA for stationary; UL limits: 3.5mA for most applications; Medical: <100µA for patient contact (use medical filters). For high leakage concerns: Use medical-grade filters for low leakage; Calculate total system leakage; Consider isolation transformers. Measurement: Use true RMS meter; Measure at rated voltage and frequency; Include all parallel paths. The EAC-06-472 leakage is well below standard limits. For medical or sensitive applications, consider medical-grade filters. Contact our FAE team for leakage analysis.
<0.5mA leakage, well below standard limits. Use medical filters for patient contact. Contact us for analysis.
How do I troubleshoot EMI issues with the EAC-06-472?
Troubleshooting EMI issues with EAC-06-472: Verify installation: Check filter mounted close to supply; Verify good ground connection; Ensure input/output wiring separated; Confirm correct wiring (not reversed). Check filter: Measure DC resistance (should be <1Ω); Check for physical damage; Verify terminals tight; Test with replacement filter. System issues: Long unfiltered input wiring; Poor system grounding; Other noise sources in system; Inadequate shielding. Improvements: Add second stage filter if needed; Improve system grounding; Add shielding to cables; Separate noisy and sensitive circuits. Measurement: Use spectrum analyzer with LISN; Identify frequency ranges failing limits; Determine if common or differential mode; Compare with and without filter.
