The **W2PV-C2S22-R2/UL** is a high-performance industrial cooling fan assembly manufactured by **Sanyo Denki** (San Ace). This specific model belongs to the **San Ace 200W** series, designed for high airflow and high static pressure in demanding environments. ### Technical Specifications | Parameter | Specification Details | | :--- | :--- | | **Manufacturer** | Sanyo Denki (San Ace) | | **Frame Size** | 200mm x 200mm | | **Thickness** | 70mm | | **Voltage** | 200V / 230V AC (50/60Hz) | | **Power Consumption** | ~50W - 65W (Depending on Hz) | | **Rotation Speed** | ~2,700 - 3,100 RPM | | **Airflow Rate** | ~335 - 395 CFM | | **Static Pressure** | ~170 - 240 Pa | | **Bearing Type** | Dual Ball Bearing | | **Safety Certification** | UL / CSA / CE | --- ### Key Electronic & Mechanical Components #### 1. AC Induction Motor Unlike smaller DC fans, this unit utilizes a rugged **AC induction motor**. It is designed for continuous 24/7 operation. The "W" designation often indicates a "Splash Proof" or highly durable design intended to withstand harsh industrial environments. #### 2. Dual Ball Bearing System The internal rotor is supported by two high-precision ball bearings. This electronic-mechanical integration ensures: * **Long Service Life:** Typically rated for 40,000 to 70,000 hours of continuous use. * **Multi-orientation Mounting:** Can be mounted vertically or horizontally without affecting bearing wear. #### 3. Thermal Protection The motor windings include an internal **thermal protector**. If the fan stalls or the internal temperature exceeds safety thresholds, the circuit will break or limit current to prevent a fire hazard, conforming to UL safety standards. #### 4. Die-cast Aluminum Frame The housing is made of aluminum rather than plastic. This acts as a **heat sink** for the motor windings, dissipating heat generated by the coils during high-speed operation. #### 5. Lead Wire Interface The "R2" suffix typically denotes the specific wiring or connector configuration. Usually, these fans come with UL-certified lead wires (3-wire or 2-wire) designed to handle high-voltage AC input. --- ### Applications * **Server Enclosures:** High-density rack cooling. * **Industrial Control Panels:** Heat dissipation for high-power inverters and PLCs. * **Telecommunications:** Cooling for outdoor base stations. * **Medical Equipment:** Large-scale imaging or diagnostic machines requiring steady airflow.
