## W2CE-1D3-R/UL: Product Overview The **W2CE-1D3-R/UL** is a high-performance, industrial-grade AC cooling fan manufactured by **Sanyo Denki** under their "San Ace" brand. These fans are designed for thermal management in enclosures, server racks, and industrial machinery. --- ### Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 100 / 115 VAC (50/60 Hz) | | **Frame Size** | 120mm x 120mm | | **Thickness** | 38mm | | **Bearing Type** | Dual Ball Bearing | | **Material (Frame)** | Aluminum Die-cast | | **Material (Impeller)** | Plastics (UL 94V-0) | | **Safety Certification** | UL / CSA recognized | | **Termination** | Lead Wires (R-Type suffix) | --- ### Detailed Electronic & Mechanical Breakdown #### 1. Motor Technology The "W" series typically utilizes a **Shaded Pole Motor** or a **Capacitor Run Induction Motor** (depending on the specific sub-series). * **Reliability:** These motors are brushless, reducing mechanical wear and electromagnetic interference (EMI). * **Protection:** It features **Burnout Protection** (impedance protected). If the fan blades are restricted or locked, the motor is designed to resist overheating and prevent fires. #### 2. Dual Ball Bearing System The use of dual ball bearings provides several advantages over sleeve bearings: * **Longevity:** Rated for approximately 40,000 to 60,000 hours of continuous operation. * **Mounting Orientation:** Can be mounted horizontally, vertically, or at any angle without affecting life expectancy. * **Heat Resistance:** Better performance in high-ambient temperature environments. #### 3. Airflow and Static Pressure * **Airflow:** Designed for high-volume air displacement to cool dense electronic components. * **Blade Design:** Optimized to minimize noise (dB) while maximizing static pressure, allowing the fan to push air through filters or cramped internal spaces. #### 4. The "UL" Suffix Importance The **UL** suffix indicates the part has passed rigorous safety testing for the North American market, specifically regarding: * **Flame Retardancy:** The plastic components will self-extinguish. * **Electrical Insulation:** High dielectric strength to prevent electrical leakage to the aluminum frame. --- ### Common Applications * **Control Panels:** Removing heat from PLCs and Power Supplies. * **Server Racks:** Maintaining ambient temperatures for networking gear. * **Medical Devices:** Reliable cooling for sensitive diagnostic equipment.
