## Electronic Specifications for W2AC-A42B-R/N The **W2AC-A42B-R/N** typically refers to a high-performance **AC Axial Fan** often used in industrial cooling and ventilation. These fans are engineered for high-pressure environments and continuous operation. --- ### 1. Key Technical Specifications Below is a breakdown of the primary electronic and mechanical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Rated Current** | Approx. 0.20A - 0.25A | | **Power Consumption** | 35W - 45W | | **Speed (RPM)** | 2,600 - 3,000 RPM | | **Airflow Capacity** | ~180 - 210 CFM | | **Noise Level** | 50 - 60 dB(A) | | **Bearing Type** | Dual Ball Bearing | --- ### 2. Electronic Components & Design The internal circuitry and electrical construction are designed for reliability and longevity: * **Motor Type:** Shaded-pole or Capacitor-run induction motor. These are brushless designs, reducing electrical noise and physical wear. * **Insulation Class:** Usually **Class B or F**, meaning the internal wiring can withstand temperatures up to 130°C - 155°C without insulation failure. * **Protection Features:** * **Impedance Protected:** The motor is designed so that if the fan is stalled, the internal resistance prevents the coils from burning out immediately. * **Thermal Protection:** Many models include an internal thermal cutout that shuts the motor down if it exceeds safe operating temperatures. * **Termination:** The "R/N" designation often refers to the lead wire or terminal configuration (e.g., Lead wires vs. Spade terminals). --- ### 3. Connection Diagram (General) Most AC fans in this series utilize a simple two-wire or three-wire connection: ```yaml Standard AC Wiring: - Brown/Black: Line (L) - 230V AC - Blue/White: Neutral (N) - Green/Yellow: Ground (GND) - Safety Chassis Ground ``` --- ### 4. Typical Applications Due to its electronic robust nature, this part is found in: 1. **Server Racks:** Heat dissipation for high-density computing. 2. **Industrial Cabinets:** Cooling for PLC and VFD electronics. 3. **HVAC Systems:** Small-scale ventilation and exhaust.
