Approvals and Compliances

Typical Applications
- Household washing machines and motor-driven appliances
- Various single-phase household appliances (washers, dryers, refrigerators, air conditioners, kitchen appliances, etc.)
- Any household appliance requiring EMI/RFI suppression to ensure motor stability and reduce interference and noise.
Product Selection Guide
- Rated Current — Select the appropriate range (3–16 A) based on the washing machine's power and starting/running current.
- Operating Voltage — Confirm the mains voltage (e.g., 110 V or 220/250 V AC).
- Filtering Stage — For motor-driven appliances, a high-suppression model is recommended (or consider a two-stage/high-suppression filter).
- Connection/Mounting — Whether plug-in, cable-driven, or screw-mounted is required depends on the equipment's internal space and structure.
- Leakage Current/Safety Requirements — Especially for household appliances, safety standards must be met.
- Certifications — CE/RoHS/UL/IEC, etc., meeting export standards and EMC requirements.
- Customization — For special equipment requirements (size/interface/current/cable length), contact DOREXS for customization.
Installation & Usage Guidance
- Install the filter in series on the power input line, ensuring all motors and electronic control circuits are powered through it.
- Keep wiring simple and short to reduce parasitic inductance and ensure effective filtering.
- For high-humidity environments (near the washing machine compartment), ensure proper grounding and metal shielding.
- Avoid routing the filter in parallel with signal lines or sensitive electronic wires to reduce coupling noise.
- If the device has a high starting current (washing machine motor startup) — it is recommended to choose a filter with a rated current close to or higher than the peak starting current.
FAQ
