The **W2TG0-3C2-R2/CE** is a high-performance industrial AC axial fan manufactured by **Sanyo Denki** (San Ace series). It is specifically designed for thermal management in heavy-duty environments like server rooms, industrial cabinets, and power supplies. --- ### ## Technical Specifications Below are the core electronic and mechanical parameters for this specific model: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Sanyo Denki | | **Input Voltage** | 230V AC (Single Phase) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | 0.08 / 0.07 A | | **Rated Power** | 15 / 13 Watts | | **Rated Speed** | 2,750 / 3,150 RPM | | **Airflow Capacity** | 35.3 / 42.4 CFM | | **Noise Level** | 35 / 40 dB(A) | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Lead Wires | --- ### ## Key Electronic Components & Features #### 1. Induction Motor Design The unit utilizes a **Shaded Pole Induction Motor**. This is common in AC fans because it is brushless and highly reliable. It uses an electromagnetic coil to create a rotating magnetic field, eliminating the need for complex commutation electronics required by DC fans. #### 2. Thermal Protection (Impedance Protection) The "R2" suffix often denotes specific protection ratings. This fan is **Impedance Protected**, meaning that even if the fan blades are physically locked (stalled), the impedance of the motor windings is high enough to prevent the current from rising to a level that would cause a fire or permanent coil damage. #### 3. Bearing System It features a **Dual Ball Bearing** system. From an electronic/mechanical perspective, this ensures: * **Longevity:** Rated for approximately 40,000 to 70,000 hours of continuous use. * **Heat Resistance:** Better stability at higher operating temperatures compared to sleeve bearings. #### 4. Dielectric Strength Being an AC-powered component, it is built with high insulation standards. It typically withstands **1500V AC for 1 minute** between the lead wires and the frame, ensuring safety against electrical leakage. --- ### ## Application Context The **/CE** suffix indicates that the part complies with European safety standards (Conformité Européenne), confirming its EMC (Electromagnetic Compatibility) and low voltage safety for the European market. This part is primarily used in: * Control panels. * Uninterruptible Power Supplies (UPS). * Laboratory equipment. ---
