The **W2TG0-4D2-R** is a high-performance, industrial-grade AC axial fan manufactured by **Sanyo Denki** (SanAce series). It is specifically designed for high-density cooling in environments requiring significant airflow and durability. --- ### 1. Key Technical Specifications The following table outlines the electronic and mechanical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Input Type** | AC (Alternating Current) | | **Rated Voltage** | 200V / 230V | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | ~0.14A / 0.12A | | **Power Consumption** | ~24W / 21W | | **Rated Speed** | 2,750 / 3,150 RPM | | **Max Airflow** | 120 / 141 CFM | | **Noise Level** | 46 / 51 dB(A) | | **Bearing Type** | Dual Ball Bearing | --- ### 2. Electronic Components & Design The "W2TG0-4D2-R" architecture consists of several critical sub-components that manage power and motion: #### A. The Motor Structure * **Shaded Pole or Capacitor-Run Motor:** Typical for this series, it utilizes a brushless AC design to minimize wear. * **Winding Insulation:** Class B insulation is standard, protecting the copper windings from heat-induced failure up to 130°C. #### B. Thermal Protection * **Impedance Protection:** The motor is electronically designed so that if the rotor is locked (stalled), the internal resistance of the windings prevents the current from rising to a level that would cause a fire or melt the components. #### C. Connectivity (The "R" Suffix) * **Termination:** The "R" usually indicates the lead wire configuration or specific RoHS compliance standards. * **Wiring:** Standard 2-wire setup (Line and Neutral) for power delivery. --- ### 3. Mechanical & Material Construction To support the electronic operation, the physical housing is built for industrial stress: * **Frame:** Die-cast aluminum (acts as a heat sink for the motor). * **Impeller:** Flame-retardant plastic (UL 94V-0 rated). * **Environmental Protection:** Designed to operate in temperatures ranging from -30°C to +70°C. --- ### 4. Applications Due to its high voltage rating and CFM (Cubic Feet per Minute) output, it is commonly found in: 1. **Server Racks:** Cooling high-density computing hardware. 2. **Industrial Control Panels:** Preventing heat buildup in PLC and inverter cabinets. 3. **Medical Equipment:** High-reliability cooling for imaging or lab machinery.
