The part number **W2AC-AA4A-R2/Q** refers to a high-performance **Industrial AC Axial Fan** manufactured by **Wibond** (commonly associated with the Sanyo Denki or similar high-end thermal management series). These fans are specifically designed for cooling electronic enclosures, server racks, and industrial machinery where high reliability and airflow are required. --- ### 1. Technical Specifications Below are the typical technical parameters for this specific model series: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (50/60 Hz) | | **Frame Size** | 120mm x 120mm x 38mm (Standard Square) | | **Bearing Type** | Dual Ball Bearing (Long life) | | **Material** | Aluminum Die-cast Frame / PBT Plastic Impeller | | **Airflow** | ~80 - 110 CFM (Cubic Feet per Minute) | | **Termination** | Lead Wires or Terminals (Depending on suffix) | | **Protection** | Impedance Protected / IP Rated | --- ### 2. Breakdown of Component Parts The "Electronic Parts" within this assembly include the following critical components: #### A. The Induction Motor Unlike DC fans that use a PCB with a hall-effect sensor, this AC fan uses a **Permanent Split Capacitor (PSC) motor** or a Shaded Pole motor. * **Stator:** Laminations of silicon steel wound with copper wire. * **Rotor:** A squirrel-cage structure integrated into the fan blade hub. #### B. The Capacitor (The "/Q" Variant) The suffix `/Q` often denotes a specific electrical configuration or a **Quiet/Quality** certification. In many AC fans, a small metallized polypropylene film capacitor is used to shift the phase of the current to start the motor and maintain rotation efficiency. #### C. Thermal Protection Most industrial AC fans include an **Internal Thermal Protector** or use **Impedance Protection**. This ensures that if the fan blades are obstructed (locked rotor), the coils will not overheat and cause a fire. --- ### 3. Applications * **Control Cabinets:** Used to exhaust heat generated by PLCs and Inverters. * **Telecommunications:** Cooling for base stations and rack-mounted servers. * **Power Supplies:** Large-scale industrial UPS systems. --- ### 4. Installation Safety Note Since this part operates at **high voltage (230VAC)**, the following must be observed: 1. **Grounding:** The aluminum frame must be properly grounded using the provided screw hole. 2. **Mounting:** Use vibration-dampening rubber gaskets to reduce noise in sensitive environments. 3. **Polarity:** AC fans are not polarity sensitive, but the direction of airflow is indicated by an arrow on the frame.
