3 Phase Line Filter Products Wholesale - VIIP Filter

Product Overview

- 3 Phase Line Filter (VIIP / VIP3 series) — an EMI/RFI power line filter family made in Shenzhen with production bases in Huizhou and Bozhou. Available in multiple formats (IEC socket, PCB, surface-mount and other installations) and a broad current range across the product line (models from ~1 A up to several hundred or more A depending on series). Typical rated voltages 380/440 V and designed for 50/60 Hz systems. Certified to CE, RoHS and TUV.

Product Features

- Low-pass EMI filter with nominal center frequency ~10 kHz–30 MHz and high insertion loss (typically 60–90 dB).

- Input impedance 50 Ω, line-to-line dielectric 1450 VDC, line-to-ground 500 VDC, and low leakage current (max ~3 mA at 480 VAC/60 Hz).

- Multiple package and mounting options (including surface mount), metal housing for durability, and customizable designs to meet customer specifications.

- Production and supply flexibility: negotiable MOQ/price, typical lead times from days to a few weeks, weekly supply capacity reported.

Product Value

- Provides strong suppression of common- and differential-mode interference to protect sensitive electronics and ensure clean, stable power.

- Reduces malfunction, data errors and downtime caused by EMI in industrial, medical and communication equipment.

- Helps equipment meet EMC requirements and regulatory standards, simplifying product certification and field reliability.

Product Advantages

- High broadband attenuation (60–90 dB) for effective suppression across a wide frequency band.

- Flexible product range and mounting options to suit diverse system architectures and retrofits.

- Custom design capability and certified quality (CE/RoHS/TUV) backed by large-scale manufacturing capacity for competitive lead times and reliable supply.

- Robust construction for industrial use and low leakage for safety-sensitive applications.

Application Scenarios

- Industrial machinery and factory automation (PLCs, drives, inverters, CNC).

- Medical devices and hospital equipment requiring low-noise power.

- Telecommunications and IT infrastructure (servers, base stations, UPS).

- Renewable energy and power conversion systems (solar inverters, energy storage, EV charging).

- Any power system or electronics installation where EMI/RFI mitigation and reliable, clean power are required.
