The **W2AC-A4CY-R** is a specific part number typically associated with professional-grade cooling solutions, most commonly high-performance AC axial fans (often manufactured by companies like **Winstar** or similar industrial thermal providers). Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | AC Axial Cooling Fan | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Bearing Type** | Dual Ball Bearing (indicated by 'B' or 'C' in certain series) | | **Frame Material** | Die-cast Aluminum (Anti-corrosion coating) | | **Impeller Material** | Thermoplastic PBT (UL 94V-0 Rated) | | **Termination** | Lead Wires (R-suffix often denotes Lead Wire version) | --- ### 2. Key Electronic Components #### A. Motor Architecture The fan utilizes a **Shaded Pole Motor** or a **Capacitor Run Motor**. These are standard for AC fans because they are reliable and do not require complex drive electronics. * **Impedance Protection:** The windings are designed to resist burning out even if the fan blades are locked (stalled) for a short period. #### B. Bearings and Lifespan The "C" or "B" in the sequence often refers to a **Dual Ball Bearing** system. * **Advantage:** Ball bearings allow the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting the lifespan. * **Life Expectancy:** Typically rated for 50,000 to 70,000 hours at 40°C. #### C. Insulation and Safety * **Insulation Class:** Usually Class B or Class F, allowing for high-temperature operating environments. * **Dielectric Strength:** Designed to withstand 1500V AC for one minute between the frame and the terminals. --- ### 3. Part Number Decoder (Typical) While specific to the manufacturer, the code usually breaks down as follows: | Segment | Meaning | | :--- | :--- | | **W2** | Series identifier (Frame size, usually 120mm x 120mm x 38mm) | | **AC** | Power source (Alternating Current) | | **A4** | Voltage code (A4 usually represents the 220-240V range) | | **C/Y** | Speed and Bearing configuration (High speed / Ball bearing) | | **R** | Specific revision or "RoHS Compliant" / "Lead Wire" indicator | --- ### 4. Implementation Code (Example) If you are integrating this fan into an automated system (e.g., via a relay with an Arduino), the basic logic for a cooling trigger would look like this: ```cpp // Logic for triggering a 220V Fan via a Relay const int tempSensorPin = A0; const int relayPin = 7; const int thresholdTemp = 35; // Celsius void setup() { pinMode(relayPin, OUTPUT); } void loop() { int sensorValue = analogRead(tempSensorPin); float voltage = sensorValue * (5.0 / 1023.0); float temperatureC = (voltage - 0.5) * 100; // Example for TMP36 if (temperatureC > thresholdTemp) { digitalWrite(relayPin, HIGH); // Turn fan ON } else { digitalWrite(relayPin, LOW); // Turn fan OFF } } ``` ---
