Stepless AC Ceiling Fan Speed Control Board

Product number:

Summary Description:

The AC motor speed control board developed by Sounds Electric supports multi-step and stepless speed regulation (up to 100 levels) to ensure smooth and precise motor operation. The board supports multiple control options including infrared remote, 433 MHz / 2.4 GHz wireless and Wi-Fi connectivity, with forward and reverse switching capability. It can also support fan light integration and airflow modes such as natural wind and sleep wind. The design complies with international certifications including UL / ETL, FCC and ICES.

Details Introduction


Stepless AC Ceiling Fan Speed Control Board

Sounds Electric's intelligent AC motor speed control board is designed for precise and stable motor speed regulation. It supports both fixed speed levels and 0–100 levels of continuous speed adjustment and is compatible with a wide range of motor power ratings and load types. With multi-protocol control and integrated protection features, the control board provides a stable and reliable drive solution for fans, ventilation equipment, small appliances, and other general motor applications.

 

Core Technology

Advanced Stepless Speed Control: Supports 0–100 levels of continuous speed adjustment as well as multiple fixed speed modes (3-speed / 5-speed / multi-speed). It ensures smooth speed transitions, stable low-speed operation, and balanced high-speed output for AC motors with different power and load characteristics.

Multiple Control Methods: Supports infrared remote control, 433MHz / 2.4GHz RF wireless control, and Wi-Fi smart control options. Forward and reverse motor direction switching is also supported to meet different market requirements.

Multiple Wind Modes: Provides natural wind, sleep mode, and standard speed settings. It also supports external fan light integration to expand overall product functionality.

 

Industrial Design Advantages

Highly Integrated Design: Integrates control, power supply, and drive modules into a compact structure, making it easier for internal wiring and system integration in various product designs.

Modular Interface Platform: Reserved interfaces for IR, RF, Wi-Fi control, fan light connection, and motor direction switching allow flexible configuration and fast customisation.

Low Noise and EMI Optimisation: Optimised electromagnetic interference control and electrical noise suppression improve silent operation and overall EMC performance.

Wide Motor Compatibility: Compatible with various AC motor specifications and different capacitor start solutions, supporting mainstream motor load characteristics.

 

Manufacturing Value

Comprehensive Quality Control: AOI inspection, functional testing, aging tests, and EMI tests ensure full traceability throughout the production process.

Flexible Customisation Services: Supports feature customisation, protocol integration, UI logic design, and structural adaptation for OEM / ODM cooperation.
