The **W2CE-5AA-R2/CE** is a high-performance **Industrial AC Cooling Fan** manufactured by **Sanyo Denki** (San Ace series). It is specifically designed for thermal management in industrial equipment, control panels, and server racks. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for this component: | Parameter | Value / Description | | :--- | :--- | | **Input Voltage** | 200V / 230V AC (Standard Range) | | **Frequency** | 50 / 60 Hz | | **Current Rating** | ~0.11A to 0.14A | | **Power Consumption** | ~18W to 22W | | **Rotational Speed** | 2,700 to 3,100 RPM | | **Max Airflow** | 88 to 106 CFM (Cubic Feet per Minute) | | **Noise Level** | ~41 to 45 dB(A) | | **Frame Size** | 120mm x 120mm x 38mm | | **Bearing Type** | Dual Ball Bearing (Long Life) | --- ### 2. Key Electronic Components & Construction The "electronic" nature of this AC fan differs from DC fans because it operates directly on line voltage without an integrated complex logic controller. * **AC Induction Motor:** Uses a capacitor-run or shaded-pole induction motor design. This ensures high reliability and the ability to run continuously for years (typically rated for 40,000 to 70,000 hours). * **Safety Thermal Protection:** This model usually features **Impedance Protection**. In the event of a rotor lock (blade blockage), the impedance of the motor windings limits the current flow to prevent the coils from overheating and catching fire. * **Dual Ball Bearings:** The electronic stability is supported by high-grade mechanical bearings that reduce friction, which in turn prevents electronic "noise" and vibration that could affect nearby sensitive sensors. * **CE Certification:** The "CE" suffix indicates that the part complies with European safety, health, and environmental protection requirements. --- ### 3. Wiring Configuration The fan typically utilizes a 2-wire lead connection. ```yaml Wiring Type: Lead Wire Polarity: AC (Phase/Neutral) Grounding: Usually grounded via the metal frame ``` ### 4. Common Applications * **Control Panels:** Cooling PLCs and power supplies. * **Server Cabinets:** Maintaining airflow in 19-inch racks. * **Industrial Machinery:** Dissipating heat from high-voltage transformers. ---
