The **W2AP-D25-R/N** is a specific part number typically associated with high-performance **Industrial AC Axial Fans**. These components are widely used in cooling systems for server racks, control cabinets, and industrial machinery. Below is a breakdown of the electronic and mechanical specifications for this part. --- ### 1. Technical Specifications The following table outlines the core electronic and operational parameters for the W2AP-D25-R/N series. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 220V / 230V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | Approximately 20W - 30W (varies by load) | | **Rated Speed** | 2,500 - 3,000 RPM | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Frame Material** | Aluminum Die-cast | | **Impeller Material** | PBT Thermoplastic (UL 94V-0 Rated) | | **Connection Type** | Lead Wire (N) or Terminal (R) | --- ### 2. Internal Electronic Components The device consists of several key electronic sub-assemblies: * **Shaded Pole or Capacitor-Run Motor:** The motor utilizes an electromagnetic induction process to rotate the impeller without the need for brushes, reducing electronic noise and wear. * **Thermal Protector:** Most models include an internal thermal fuse or impedance protection to prevent the coils from burning out if the motor stalls. * **Stator Windings:** Copper windings insulated with high-temperature resin to withstand continuous industrial operation. ### 3. Model Suffix Deciphering The suffix **-R/N** usually indicates the wiring configuration: 1. **"R" (Terminal Type):** Features metal pins/terminals on the frame for quick-connect plugs. 2. **"N" (Lead Wire Type):** Features standard insulated copper wires for direct soldering or wire-nut connections. --- ### 4. Implementation Example If you are integrating this fan into a control system using an Arduino or PLC, you would typically use a Relay or a Solid State Relay (SSR) because it operates on AC mains voltage. ```cpp // Example: Using a Relay to control the AC Fan int relayPin = 8; void setup() { pinMode(relayPin, OUTPUT); } void loop() { // Turn fan ON digitalWrite(relayPin, HIGH); delay(60000); // Run for 1 minute // Turn fan OFF digitalWrite(relayPin, LOW); delay(60000); } ```
