The **W2TG0-3C2-R/N** belongs to a series of industrial-grade AC cooling fans, typically manufactured by brands like **Wintek** or **Wiltopu**. These components are critical for thermal management in server racks, power supplies, and industrial control cabinets. --- ### 1. Technical Specifications The following table outlines the typical electrical and mechanical characteristics of this specific model: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Current Consumption** | ~0.14A - 0.22A (varies by load) | | **Input Power** | ~22W - 30W | | **Rotational Speed** | 2600 - 3000 RPM | | **Airflow Capacity** | ~90 - 110 CFM | | **Bearing Type** | Dual Ball Bearing (Highly Durable) | | **Material** | Aluminum Die-cast Frame / PBT Plastic Impeller | --- ### 2. Key Electronic Components & Features The W2TG0-3C2-R/N is more than just a motor; it integrates several electronic protections and design elements: * **Shaded Pole or Capacitor-Run Motor:** It utilizes an induction motor design optimized for AC power. The "3C2" designation often refers to the internal winding configuration and capacitor requirements for starting torque. * **Impedance Protection:** The motor windings are designed to withstand a "locked rotor" state. If the blades are obstructed, the internal impedance prevents the coils from overheating and catching fire. * **Insulation Class:** Usually rated as **Class B or Class F**, meaning the internal wiring insulation can withstand temperatures up to 130°C or 155°C respectively. * **Terminals vs. Leads:** The "R/N" suffix often indicates the connection type—typically **Terminal lugs** (fast-on connectors) rather than stripped wire leads, allowing for easy replacement in industrial racks. --- ### 3. Usage and Safety To integrate this part into an electronic system, consider the following: 1. **Grounding:** Since the frame is aluminum, it must be properly grounded via the designated grounding screw hole to prevent electric shock. 2. **Directionality:** Ensure the arrow on the frame matches the intended airflow (Exhaust vs. Intake). 3. **EMI/RFI:** As an AC motor, it may generate minor electromagnetic interference. In sensitive audio or medical equipment, shielding may be required. ---
