The **W2AC-A32D-R2** is a specific model of an AC-powered **Compact Axial Fan**, typically manufactured by brands like Sanyo Denki (San Ace). These fans are designed for high-reliability cooling in industrial cabinets, servers, and power supplies. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Model Number** | W2AC-A32D-R2 | | **Input Voltage** | 230V AC (Standard Range: 200V - 240V) | | **Frequency** | 50/60 Hz | | **Current Type** | Alternating Current (AC) | | **Bearing Type** | Dual Ball Bearing (High Durability) | | **Housing Material** | Aluminum Die-cast | | **Impeller Material** | Plastic (UL 94V-0 Rated) | | **Termination** | Lead Wires (R2 often denotes specific wire length or connector) | --- ### 2. Key Electronic Components & Design The internal electronics of this unit are specialized for converting AC wall power into mechanical rotation: #### A. Shaded Pole or Capacitor-Run Motor Most AC fans of this series use a **Shaded Pole induction motor** or a **Permanent Split Capacitor (PSC)** motor. These do not require complex driver boards like DC fans, making them highly resistant to electromagnetic interference (EMI). #### B. Dual Ball Bearing System The "Electronic" longevity of the fan is supported by its mechanical bearings. Dual ball bearings allow the fan to operate at high temperatures (up to 70°C) without the lubricant drying out as quickly as in sleeve bearing models. #### C. Thermal Protection The motor windings usually include an **Impedance Protection** or a **Thermal Cutoff**. This prevents the electronics from catching fire if the fan blades are physically obstructed (locked rotor condition). #### D. Dielectric Strength The insulation is designed to handle high-voltage spikes, typically tested at 1500V AC for one minute between the lead wires and the frame. --- ### 3. Wiring Configuration | Wire Color | Function | Description | | :--- | :--- | :--- | | **Black** | Line (L) | Connects to the AC Live phase. | | **Black (or White)** | Neutral (N) | Connects to the AC Neutral. | | **Green/Yellow** | Ground (G) | Attached to the aluminum frame for safety (if applicable). | --- ### 4. Application Areas * **Control Panels:** Heat dissipation for PLCs and Inverters. * **Network Racks:** Cooling for switches and routers. * **Medical Equipment:** Reliable airflow for power supplies.
