A high-performance single-phase EMI noise filter designed for 220 V power systems, the DAA1 series from DOREXS delivers superior suppression of conducted and radiated electromagnetic interference. Engineered for industrial equipment, automation systems and noise-sensitive applications, it ensures robust EMC compliance and stable operation.

Features

  • Excellent attenuation of both common-mode and differential-mode noise over a wide frequency band (150 kHz to 30 MHz)
  • Rated current range from 1 A to 10 A at 220 V AC — ideal for small to medium load systems
  • Compact chassis mount design for space-saving installation
  • Low leakage current version available for use in safety-critical and medical applications
  • Meets international standards including IEC/EN 60939, UL 1283 and RoHS compliance
  • Customization available: special mounting, enhanced insulation, tailored leakage current, specific insertion-loss targets

Approvals and Compliances 

Approvals and Compliances 
The DAA1 series single-phase EMI noise filters comply with IEC/EN 60939, UL, CE, and RoHS electromagnetic interference suppression filter standards. A medical-grade version is available that complies with IEC 60601 equipment leakage current standards.

Applications

  • Lighting equipment
  • LED drivers
  • Industrial and architectural lighting
  • Consumer appliances.

Technical Advantages

  • Up to 60 dB attenuation at 150 KHz-10 MHz (depending on configuration) — effectively prevents noise from reaching other equipment
  • Optimized filter circuit design reduces harmonic distortion and improves overall power signal integrity
  • Built for harsh industrial environments with stable performance across –25 °C to +85 °C operating temperature
  • Single-phase 220 V compatibility makes it an easy upgrade for global systems

FAQ

1. Product Selection Guide

When selecting the right filter from the DAA1 series, please consider:
  1. Your system’s rated current (choose 1A, 2A, 3A … up to 10A)
  2. Whether low leakage current is required (e.g., for medical or safety equipment)
  3. Mounting style (chassis mount, snap-in, PCB mount)
  4. Environmental conditions (ambient temperature, vibration, humidity)
  5. EMC test target level / required insertion loss

2. Installation Instructions

  1. Connect the filter in series with the power line (line to filter input, filter output to load)
  2. Keep wiring between filter and load as short as possible to minimise parasitic inductance
  3. Ground the filter housing firmly, ensuring proper protective earth
  4. Avoid routing the filter output cables parallel to noise-sensitive signal wiring
