The **W2CE-51D-R2/N** is a specific model within a series of industrial-grade **AC Axial Fans**, typically manufactured by brands like **Wizone** or associated with high-performance cooling solutions for electronic cabinets and machinery. --- ### 1. Technical Specifications Overview Based on the standard nomenclature for the W2CE series, here are the primary electronic and mechanical characteristics: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 110V - 120V AC (50/60Hz) | | **Power Consumption** | Approx. 18W - 22W | | **Current Rating** | ~0.20A | | **Rotation Speed** | 2,700 - 3,000 RPM | | **Airflow Capacity** | 85 - 105 CFM (Cubic Feet per Minute) | | **Bearing Type** | Dual Ball Bearing (indicated by "2") | | **Frame Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (PBT) UL94V-0 | --- ### 2. Breakdown of the Model Code The part number can be decoded to understand its electronic configuration: * **W2CE**: The series designation (Standard AC Axial Fan, typically 120mm x 120mm x 38mm). * **51**: Represents the voltage class (typically 115V AC). * **D**: Indicates the motor type or specific airflow performance (High Speed). * **R2**: Refers to the **Dual Ball Bearing** system, which increases the lifespan of the electronic component compared to sleeve bearings. * **N**: Often signifies compliance or a specific termination type (e.g., Lead wires or RoHS compliance). --- ### 3. Electronic Components and Protection The internal circuitry of the W2CE-51D-R2/N includes several critical electronic safety features: * **Shaded Pole Motor:** A simple, robust AC motor design that uses a copper ring (shading coil) to create a rotating magnetic field. * **Impedance Protection:** The motor windings are designed to limit current flow even if the fan blade is physically stalled. This prevents the coils from overheating and catching fire. * **Insulation Class:** Usually **Class B or F**, rated to withstand temperatures up to 130°C–155°C. * **Connection Type:** Typically features two lead wires for direct connection to an AC power source. --- ### 4. Typical Applications These fans are used in environments where high-reliability cooling is required: 1. **Server Racks:** Removing heat from power supplies and processors. 2. **Industrial Control Panels:** Preventing overheating in PLCs and Inverters. 3. **Medical Equipment:** Cooling high-precision electronic diagnostic tools. 4. **Vending Machines:** Air circulation for internal electronics.
