The **W2TG0-2C3-R** is a specific part number typically associated with high-performance cooling fans, specifically those manufactured by **Sanyo Denki** under the **San Ace** brand. These fans are commonly used in industrial computing, servers, and power supplies. Below is a detailed breakdown of the electronic and mechanical specifications for this component. --- ### 1. General Specifications The W2TG0-2C3-R belongs to a series of high-reliability AC or DC fans (depending on the specific sub-series, though most W-series are high-airflow AC fans). | Feature | Description | | :--- | :--- | | **Manufacturer** | Sanyo Denki | | **Series** | San Ace (Long Life / High Airflow) | | **Type** | Axial Cooling Fan | | **Material** | Aluminum Frame, Plastic Impeller (UL 94V-0) | | **Bearing Type** | Dual Ball Bearing | ### 2. Electronic Characteristics The "2C3" and suffix "R" indicate specific electrical configurations and protection features. * **Input Voltage:** Typically operates on AC power (often 200V-230V range for the 2C series), though it is essential to verify the specific voltage label as variations exist. * **Safety Protection:** * **Burnout Protection:** The motor is designed to withstand a locked-rotor condition without catching fire or sustaining internal damage. * **Reverse Polarity Protection:** Integrated into the internal circuitry (for DC variants). * **Termination:** Usually features lead wires (Red/Black or Brown/Blue) or specialized connectors depending on the "R" suffix customization. ### 3. Mechanical and Environmental Performance These fans are engineered for 24/7 operation in demanding environments. | Metric | Estimated Value | | :--- | :--- | | **Life Expectancy** | 40,000 to 100,000 hours (at 40°C) | | **Operating Temperature** | -10°C to +70°C | | **Speed Control** | Fixed speed (Standard) | | **Noise Level** | Designed for optimized airflow-to-noise ratio | ### 4. Key Components and Materials 1. **Motor:** A brushless permanent magnet motor or AC induction motor designed for low vibration. 2. **Bearings:** High-precision dual ball bearings are used to ensure the fan can be mounted in any orientation (horizontal or vertical) without losing its lifespan. 3. **Circuitry:** Features an internal PCB for motor commutation and thermal protection. --- ### Common Applications * **Server Racks:** To exhaust heat from dense CPU environments. * **Inverters/UPS:** To cool power electronics that generate significant heat during conversion. * **Industrial Machinery:** Used in control panels to prevent overheating of PLCs and drives.
