The part number **W2TG0-4CA-R2SLASHCE** (often written as **W2TG0-4CA-R2/CE**) refers to a specific configuration of a high-performance **Industrial Fan** manufactured by **Sanyo Denki**, specifically under the **San Ace** brand. These are high-voltage, high-efficiency AC fans used primarily in server racks, industrial control panels, and telecommunications equipment. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Manufacturer** | Sanyo Denki | | **Series** | San Ace (AC Fan) | | **Frame Size** | 120mm x 120mm x 38mm | | **Rated Voltage** | 200V / 230V AC (50/60Hz) | | **Bearing Type** | Dual Ball Bearing | | **Material** | Aluminum Frame / Plastic Impeller (UL 94V-0) | | **Protection** | Burnout protection at locked rotor condition | | **Connection Type** | Lead Wire or Terminal (Variant dependent) | --- ### 2. Breakdown of the Part Characteristics The internal electronic components and design of this fan focus on longevity and thermal management: * **Motor Technology:** It utilizes a shaded-pole or capacitor-run induction motor (depending on the specific R2 sub-revision) designed to operate continuously for over 40,000 to 60,000 hours. * **Dual Ball Bearings:** Unlike sleeve bearings, the dual ball bearing system allows the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting its lifespan. * **Safety Compliance (/CE):** The suffix "CE" indicates that the electronics and insulation meet European safety, health, and environmental protection requirements. * **Thermal Protection:** The windings are impedance protected or thermally protected to prevent the fan from catching fire if the blades are physically obstructed. --- ### 3. Application Use-Cases The electronics in the **W2TG0** series are built for harsh industrial environments: 1. **Power Supplies:** Cooling high-wattage industrial power converters. 2. **Server Cabinets:** Maintaining airflow in 19-inch racks. 3. **Factory Automation:** Cooling PLC enclosures and motor drives where 200V-230V power is readily available. --- ### 4.
