VIP5-4AG5-50-S(30004), is a heavy-duty industrial EMC power EMI filter with 50A rated current, engineered to curb conducted electromagnetic interference on power circuits. It supports 380/440VAC working voltage and fits 50/60Hz utility power networks.

This filter achieves outstanding noise attenuation when tested in a standard 50-ohm setup. At 440VAC and 50Hz, its maximum earth leakage current per line caps at 3.2mA. Under 500VDC testing, the insulation resistance between input / output terminals and ground exceeds 200M ohm. It can withstand a one-minute dielectric strength test: 2700VDC between line and ground, and 2250VDC between separate power lines. The operating temperature range covers -25°C to +85°C, making it adaptable to harsh industrial ambient conditions.

This power EMI filter offers two-way noise blocking. It shields sensitive hardware from mains-borne electromagnetic disturbances, and contains high-frequency interference emitted by heavy-duty loads to prevent grid contamination. It assists end products in meeting EMC regulatory requirements and maintains reliable long-run operation.

FAQs

FAQ 1: What is common-mode noise and differential-mode noise?

Common-mode noise refers to interference signals that appear equally on all power lines relative to ground. Differential-mode noise is interference that exists between power lines. EMI filters are built to attenuate both types of noise simultaneously.

FAQ 2: Can I install the EMI filter inside the metal cabinet of my machine?

Yes, installation inside a metal cabinet is common. To retain full filtering performance, mount the filter housing firmly to the cabinet metal plate for good grounding. Keep the input and output cables separated to avoid noise coupling.

FAQ 3: What will happen if the EMI filter works beyond its rated voltage?

Operating above rated voltage will overload the internal capacitors. It may cause capacitor breakdown, permanent filter damage, and even safety hazards such as short circuit. Always use the filter within its specified voltage rating.

FAQ 4: Does an EMI filter need maintenance during normal use?

Industrial EMI filters have no consumable parts and require little routine maintenance. Periodically check terminal screw tightness and inspect for overheating or casing damage. Replace the filter if you find bulging capacitors or burnt marks.

FAQ 5: What is the difference between EMC and EMI?

EMI stands for Electromagnetic Interference, which is the unwanted electromagnetic noise. EMC (Electromagnetic Compatibility) means equipment can work properly in its electromagnetic environment without emitting excessive noise. EMI filters are key components to achieve EMC compliance.
