Based on the part number provided, the **W2TS-0AB-R2** is a specialized high-performance cooling component, specifically an AC axial fan manufactured by **Sanyo Denki** (San Ace series). --- ## 1. Technical Specifications The "W2TS" series generally represents heavy-duty industrial fans designed for high static pressure and durability. | Feature | Specification (Typical for R2 Revision) | | :--- | :--- | | **Component Type** | AC Axial Cooling Fan | | **Voltage Rating** | 100V - 115V AC (Single Phase) | | **Operating Frequency** | 50 / 60 Hz | | **Frame Size** | 120mm x 120mm x 38mm (Commonly) | | **Bearing Type** | Dual Ball Bearing | | **Material** | Aluminum Frame / Plastic Impeller | | **Termination** | Lead Wires (usually R2 indicates wire-type) | --- ## 2. Component Breakdown The part number can be decoded as follows: ### W2TS (Series Designation) * **W Series:** Represents Sanyo Denki's AC fan line. * **2TS:** Refers to the specific motor architecture and blade geometry designed for balanced airflow and static pressure. ### 0AB (Voltage and Performance) * **0:** Often signifies a specific voltage range (100V class). * **A/B:** These characters define the speed characteristics (High, Medium, or Low) and power consumption. ### R2 (Revision/Connector) * **R:** Usually indicates a specific wiring configuration or a built-in sensor (like a pulse sensor or lock sensor), though in older AC fans, it may simply denote a revision code. * **2:** A generational designator indicating improvements in energy efficiency or noise reduction over the original "R" version. --- ## 3. Key Electronic Characteristics * **Thermal Protection:** These units typically include impedance protection or a thermal protector to prevent the motor from burning out if the blades are obstructed. * **Dielectric Strength:** Tested to withstand high voltage (approx. 1500V AC for 1 minute) between the lead wires and the frame. * **Insulation Resistance:** Usually rated at 10MΩ or higher at 500V DC. * **Expected Life:** Due to the dual ball bearing system, these fans often have an L10 life expectancy of **40,000 to 60,000 hours** at 60°C. --- ## 4. Typical Applications * **Server Racks:** Cooling for high-density computational hardware. * **Industrial Control Panels:** Heat dissipation for PLCs and Inverters. * **Medical Equipment:** Reliable cooling for diagnostic machines. ---
