Product Brief

VIP5-4AG5-50-S(30004), is a high-performance EMC power EMI filter built to suppress conducted electromagnetic interference on power lines. It carries a rated current of 50A RMS and a rated working voltage of 380/440VAC, compatible with 50/60Hz power systems.

This filter delivers reliable insertion loss performance measured under a standard 50-ohm test environment. At 440VAC and 50Hz, its maximum line-to-ground leakage current is limited to 3.2mA. When tested at 500VDC, the insulation resistance between input/output terminals and ground exceeds 200M ohm. It passes the 1-minute hipot withstand test: 2700VDC for line to ground and 2250VDC for line to line. The operating temperature covers -25°C to +85°C.

The unit effectively attenuates electromagnetic noise on power circuits. It protects sensitive equipment from external EMI disturbance and stops noise generated by high-power loads from flowing back into the mains grid, assisting end products to meet EMC compliance requirements.

New 5 General FAQs for EMI Filters

FAQ 1: What is insertion loss for EMI filter?

Insertion loss is the core index to evaluate noise filtering capability. It refers to the noise attenuation level (in dB) after installing the EMI filter. Higher dB value means better noise suppression effect. The test is usually carried out under a 50-ohm system.

FAQ 2: What is the difference between line-to-ground and line-to-line hipot test?

Line-to-ground hipot test checks insulation strength between power lines and the filter housing/earth. Line-to-line hipot test verifies insulation between different power conductors. Both tests confirm the filter can resist high voltage without breakdown for safe operation.

FAQ 3: What factors should I consider when selecting an EMI filter?

Key selection parameters include rated voltage, rated current, working frequency, leakage current, insertion loss, operating temperature range and installation space. It is also necessary to match the EMC test requirements of your end device.

FAQ 4: Can EMI filter eliminate all electromagnetic interference?

No. EMI filters mainly suppress conducted interference transmitted through power cables. Radiated electromagnetic noise transmitted through air cannot be fully removed by EMI filter alone. Shielding and proper grounding are also needed together.

FAQ 5: What precautions should be taken during EMI filter installation?

Keep input wires and output wires separated and avoid cross winding. Use short wiring. Ensure reliable grounding with low resistance. Do not install the filter in high-temperature or heavily vibrating areas, to guarantee the designed filtering performance.
