DAA2-line single phase EMI filters are designed for use in electronic equipment and power systems to suppress electromagnetic interference (EMI). There are two installation methods (power cord link and plug-in installation). This series of single phase line filters are usually composed of capacitors, inductors and resistors, with the same rated voltage of 220V and rated current of 1A-10A. We also provide customized models with a maximum current of up to 50A.

Features 

  • The DAA2 line EMI filter effectively suppresses electromagnetic interference in power lines.
  • The DAA2 line EMI filter effectively filters out harmonic signals in power lines.
  • Excellent differential-mode and common-mode interference suppression.
  • Overvoltage protection.
  • Compact design, easy installation.
  • Multiple installation options available, including cable connection or standard 6.3×0.8mm pin connector.
  • Customization supported (cable length, connector type, parameters, etc.).
  • Free samples available.

Approvals and Compliances 

Approvals and Compliances 
The DAA2-Line series of single-phase EMI noise filters comply with IEC/EN 60939, UL, CE, and RoHS electromagnetic interference suppression filter standards. A medical-grade version compliant with IEC 60601 equipment leakage current standards is also available. 

Applications

  • Lighting equipment
  • LED drivers
  • Industrial and architectural lighting
  • Consumer appliances.
This product is particularly suitable for applications requiring small size, good interference suppression, and flexible installation.

Installation Instructions

  • Connect the DAA2-Line filter in series with the power line to ensure effective filtering of high-frequency noise.
  • If using a cable connection, keep the cable as short as possible to reduce additional parasitic inductance.
  • Pin-mount (6.3 × 0.8 mm) filters should be installed using the correct type of socket or pad.
  • Ensure good grounding — good grounding is critical for suppressing common-mode interference.
  • Avoid running the filter cable parallel to high-frequency sensitive signal lines to prevent interference coupling.
