Single‑Phase Two‑Stage EMI RFI Power Line Filter VIP4‑2B‑20(B042Q0707),20A 115/250VAC 50‑60Hz High Insulation Resistance Conducted Noise Reduction Filter for EMC Compliance Testing

Product Overview

VIP4‑2B‑20 (B042Q0707) is a VIIP single-phase two-stage AC EMI filter rated 20A RMS, operating at 115/250VAC, 50/60Hz. This chassis mount filter cleans up power line disturbances, cuts down common-mode and differential-mode high-frequency noise from AC mains. It stabilizes input power quality for power conversion systems and prevents equipment-generated noise from leaking back to the utility grid. It meets global environmental standards and delivers consistent filtering performance for continuous power applications.

Product Highlights

Dual-stage LC topology for balanced attenuation of common-mode and differential-mode EMI noise
20A RMS continuous current rating for single-phase AC mains input
Optimized low leakage current to satisfy IEC safety requirements for end equipment
Reinforced insulation structure, high insulation resistance and strong dielectric withstand capability
Heavy-duty metal shield casing prevents electromagnetic noise leakage
Stable performance across wide operating temperature range: -25℃ ~ +100℃
Screw terminal connections for secure, high-reliability wiring

Applications

Safety-certified industrial control panels
Non-life-support medical auxiliary electronics
Building automation and smart control systems
Commercial lighting control equipment
Security monitoring systems and fire alarm devices
Electronic devices with strict electrical safety requirements

Frequently Asked Questions

What is your MOQ for VIP4-series power filters?

For standard off-the-shelf VIP4 series models, low MOQ is acceptable. Stock items support small-batch trial orders; for bulk mass production orders, MOQ will be based on production arrangement. Contact our sales team for detailed MOQ information.

Can I get samples of VIP4-series filters for my internal EMC performance pre-test?

Yes, sample service is available. Standard VIP4 models can be supplied as samples for your lab EMC validation and performance verification. Sample freight will be borne by the buyer.

What are the rated voltage, rated current and operating frequency for VIP4-series power filters?

VIP4 series single-phase filters are rated at 115/250VAC, operating frequency 50/60Hz. Different part numbers support different rated current from 1A-10A (for example VIP4-2B-10 is 10A model). Please refer to the product approval sheet for exact parameter of each model.

Can you provide insertion-loss curves including common-mode and differential-mode performance for VIP4-series filters?

Yes. Insertion-loss data under 50Ω standard test system is included in each model's approval sheet. We can provide test curves for common-mode and differential-mode noise attenuation for your circuit simulation and EMC evaluation.

What is the hip-pot (high-potential) test standard for VIP4-series power filters?

Every finished VIP4 filter undergoes hip-pot withstand voltage test for 1 minute as per specification, together with insulation resistance test (≥100MΩ @500VDC input/output to ground). Full test specification is shown on the approval sheet.

If my product fails during EMC testing after using VIP4 filters, can you provide technical support?

Yes, our in-house EMC engineering team can offer technical support. Please share your test report, application condition and circuit information, we will analyze and give suggestions for improvement or model adjustment.

Could you help select proper VIP-series filter model for my specific application such as inverter, servo drive or control cabinet?

Sure. Please provide key information including working voltage, rated current, equipment type, main noise frequency and installation condition. Our team will help you pick the most suitable filter solution for your system.
