The **W2CE-1D3-R2/UL** is a specific model of an industrial fan, typically categorized as a compact axial fan used for cooling electrical cabinets, machinery, and electronic enclosures. This model is often associated with manufacturers like **Fulltech Electric**. --- ### Technical Specifications The following table outlines the primary electronic and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Single Phase) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | Approx. 0.20A / 0.18A | | **Power Input** | 20W / 18W | | **Speed (RPM)** | 2600 / 3000 RPM | | **Airflow Capacity** | ~80 / 100 CFM | | **Bearing Type** | Dual Ball Bearing | | **Safety Certification** | UL / cUL / CE | --- ### Electronic Components & Design #### 1. Motor Construction The fan utilizes an **AC Shaded Pole Motor** or a **Permanent Split Capacitor (PSC)** motor design. * **Winding:** The internal coils are wound with high-grade copper wire, insulated to withstand thermal stress (usually Class B or F insulation). * **Impedance Protection:** This model usually features internal impedance protection, meaning that if the rotor is locked (prevented from spinning), the electronic resistance of the windings prevents the motor from overheating or catching fire. #### 2. Bearing System It employs a **Dual Ball Bearing** system. Electronically and mechanically, this is superior to sleeve bearings because: * It can operate in any orientation (horizontal, vertical, or angled). * It has a significantly higher Mean Time Between Failures (MTBF), often exceeding 50,000 hours. #### 3. Housing and Connectivity * **Frame:** Typically made of Die-Cast Aluminum, which acts as a heat sink for the internal motor. * **Terminals:** The "R2" suffix often denotes the connection type. It usually features **lead wires** or **terminal pins** for direct integration into a power circuit. * **Capacitor:** Some versions may include an integrated run-capacitor to shift the phase and provide the necessary starting torque. --- ### Safety and Compliance The **UL** suffix indicates that the part has been tested and certified by *Underwriters Laboratories*. This is critical for industrial applications as it ensures: 1. **Flame Retardancy:** The plastic blades (often PBT thermoplastic) meet UL94V-0 standards. 2. **Dielectric Strength:** The unit can withstand high voltage surges without insulation breakdown. ---
