The **W2AC-A1CA-R2/Q** is a specific technical configuration for an industrial cooling solution, primarily associated with the **W2AC series** of high-performance AC axial fans. These are typically used in server racks, power supplies, and industrial control cabinets. ### 1. Part Number Breakdown Understanding the electronic and mechanical characteristics through the nomenclature: | Component | Code | Description | | :--- | :--- | :--- | | **Series** | W2AC | Compact AC Axial Fan series | | **Voltage** | A1 | Typically indicates 110V - 115V AC input | | **Material** | C | Aluminum die-cast housing / Plastic impeller | | **Bearing** | A | Precision Ball Bearing system | | **Revision/Spec** | R2/Q | Specific internal revision for RoHS compliance and Quiet/Quality testing | --- ### 2. Key Electronic Specifications The internal electronics are designed for continuous operation (24/7) in harsh environments. * **Motor Type:** Shaded-pole motor or Capacitor-run induction motor (depending on specific wattage). These motors are brushless and have no electronic commutators to wear out. * **Operating Voltage:** 115V AC (standard for A1 designation). * **Frequency:** Compatible with both 50Hz and 60Hz. * **Insulation Class:** Class B or Class F (Rated for temperatures up to 130°C - 155°C). * **Protection:** * **Impedance Protected:** The motor electronics are designed to limit current so the windings won't burn out even if the fan blade is physically locked. * **Thermal Protection:** Often includes an internal thermal cutoff. --- ### 3. Mechanical & Environmental Characteristics The electronics are housed within a rugged frame to ensure EMI (Electromagnetic Interference) shielding. | Feature | Specification | | :--- | :--- | | **Housing Material** | Die-cast Aluminum (acts as a heat sink for the motor) | | **Bearing System** | Dual Ball Bearings (provides ~50,000+ hour lifespan) | | **Connection** | Lead wires or Terminal lugs (depending on the R2 suffix) | | **Termination** | UL1007 AWG 22-24 wires (typical) | --- ### 4. Typical Applications Because of the high-reliability AC motor, this part is commonly found in: 1. **Industrial Enclosures:** Cooling for PLCs and VFDs. 2. **Medical Equipment:** High-reliability cooling for imaging or lab hardware. 3. **Telecommunications:** 19-inch rack cooling units. ---
