3. Main Circuit Functional Modules

3.1 Stable AC-DC Conversion Circuit

Built-in isolated transformer conversion module converts mains alternating current into steady 12V direct current for exhaust fan operation. Matched with multi-group capacitor and inductor filter components to reduce current ripples, maintaining consistent fan running speed.

3.2 Specialized DC Motor Drive Circuit

Optimized drive circuit layout tailored to the power demand of small exhaust fan DC motors. It ensures smooth fan rotation and stable exhaust air volume under continuous long-hour operation.

3.3 Complete EMC Filter Structure

Multiple filter resistors, capacitors and inductors are reserved on the PCB to suppress electromagnetic interference generated during fan operation, assisting finished exhaust fans in passing standard EMC certification tests.

3.4 Multi-Layer Safety Protection Circuit

Integrated over-current, over-voltage, short-circuit and overload protection circuits. When abnormal current or voltage occurs, the circuit will cut off output automatically to lower potential safety hazards for ventilation equipment.

3.5 Standardized Terminal Interface Design

Multiple unified plug terminals are preset on the board, facilitating wiring connection during exhaust fan assembly and adapting to automated factory production workflows.

4. Solution Core Advantages

4.1 Targeted Design for DC Exhaust Fans

The circuit layout and PCB size are customized to fit the internal installation space of mainstream wall-mounted DC exhaust fans. No large-scale mold modification is needed for most existing exhaust fan production lines.

4.2 Integrated All-in-One Circuit Structure

Single PCB integrates power conversion and fan drive functions, eliminating the need for separate power adapter modules. It simplifies the internal structure of finished exhaust fans, reduces accessory procurement categories and cuts assembly labor costs.

4.3 Mature Mass-Production Verified Circuit Scheme

All electronic components adopt standardized matching combinations validated by batch manufacturing. The circuit maintains reliable performance under long-term continuous working conditions, effectively reducing the after-sales failure rate of finished exhaust fans.

4.4 Universal 12W Power Matching Compatibility

The 12VDC 1A, 12W rated specification is compatible with most small household DC exhaust fan motor configurations, supporting direct assembly without secondary circuit adjustment for mainstream ventilation fan products.

4.5 Flexible Bulk Supply & OEM Support

The finished HSH-SF04-010 model supports stable mass order delivery. Minor circuit parameter adjustments can be carried out according to customized functional requirements from exhaust fan manufacturers.

5. Application Scope

This control board is exclusive matching electronic spare parts for DC exhaust fans. Applicable scenarios include core control hardware for new DC exhaust fan development, replacement maintenance circuit boards for finished ventilation fans, and supporting PCB accessories for home appliance OEM & ODM factories. It is suitable for indoor exhaust fans used in bathrooms, kitchens, storage rooms and small enclosed spaces.

6. Commercial Value for Ventilation Equipment Manufacturers

  1. Ready-made mature circuit board saves independent circuit R&D investment and shortens the launch cycle of new exhaust fan products.
  2. Integrated power supply and drive design reduces the quantity of assembly parts, lowering overall production and material costs.
  3. Built-in full filtering and protection circuits simplify the certification process of finished exhaust fans for various regional markets.
  4. Standardized terminal layout and fixed PCB outline match existing automated assembly lines to improve factory production efficiency.
