TheDEA5 EMI filter is a heavy-duty single-phase power line filter with a rated current of 20 A to 30 A, suitable for AC 115/250 V (standard 220 V) systems. It features a two-section/double filter circuit design, providing excellent suppression of common-mode and differential-mode interference in the 10 kHz–30 MHz frequency range.
It supports various connection methods (cable/screw terminals/quick-connect terminals), and parameters can be customized according to customer requirements. Sample testing is also available.  It holds international certifications such as UL, CE, and RoHS, making it ideal for industrial, medical, commercial, and high-power applications.

Key Features

  • Two-stage filter design – effectively suppresses common-mode and differential-mode noise.
  • Rated current 20 A–30 A, suitable for medium to high-power systems.
  • Low leakage current.
  • Wide frequency suppression range of 10 kHz–30 MHz, covering common EMI interference from power lines and switching equipment.
  • Multiple connection/mounting options: cable/bolt terminals/quick-connect terminals (6.3×0.8 mm) – for easy and quick installation.
  • Excellent insulation and voltage withstand characteristics: line-to-line 1500 VDC, line-to-ground 2150 VAC, insulation resistance > 50 MΩ@500VDC.
  • Robust structure, suitable for heavy-duty and harsh environments – ideal for industrial equipment, automation, medical devices, high-power equipment, etc.
  • Customization (connection methods/parameters) and sample evaluation available – suitable for OEM/ODM customers.

Selection Guide

When selecting a DEA5 EMI filter, please consider the following factors:
  1. Rated Current — Choose the 20 A or 30 A model based on the maximum load of your equipment.
  2. Connection/Mounting Method — Select cable, bolt terminals, or quick-connect terminals based on your equipment design and ease of installation.
  3. Required Noise Suppression Strength and EMI Environment Complexity — For environments with severe EMI, a two-stage design provides stronger suppression.
  4. Interference Frequency Range — Particularly suitable for systems that generate or are exposed to noise in the 10 kHz–30 MHz range (such as motors and switching power supplies).
  5. Voltage and Insulation Requirements — Supports 115/250 VAC, with a line-to-ground withstand voltage of 2150 VAC and high insulation resistance, suitable for equipment with high safety requirements.
  6. Customization/Sample Testing — If specific connection methods or parameters are required, please contact us for customization and sample evaluation.

Installation Instructions

  • Connect the DEA5 filter in series with the AC power line (live wire + neutral wire) for optimal filtering performance.
  • Select the appropriate connection method (cable/screw terminals/quick-connect terminals) according to the equipment design.
  • Keep the connecting wires as short as possible to reduce parasitic inductance and improve filtering attenuation.
  • Ensure reliable grounding when necessary, especially in equipment with high EMC requirements.
  • Avoid routing sensitive signal lines parallel to the power line filter to reduce coupling interference.
