The **W2TG0-4D1-R2/N** is a specialized electronic component primarily associated with industrial cooling solutions, specifically high-performance AC axial fans. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Overview This part belongs to a series of high-efficiency axial fans designed for thermal management in telecommunications, server enclosures, and industrial control cabinets. The suffix **"/N"** usually denotes a specific variation in bearing type or environmental protection (such as moisture resistance). ### 2. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Operating Voltage** | 115V AC (standard for the W2T series) | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | Approximately 20W - 24W | | **Airflow Capacity** | ~100 - 115 m³/h (depending on frequency) | | **Bearing Type** | Dual Ball Bearing (Standard for R2/N models) | | **Motor Protection** | Impedance Protected | --- ### 3. Electronic Design Features #### A. Motor Architecture The fan utilizes a **shaded-pole motor** or a **permanent split capacitor motor** (depending on the exact revision). These are brushless AC motors, which are electronically simpler and highly reliable for long-term continuous operation. #### B. Electronic Protection * **Impedance Protection:** The motor windings are designed so that if the fan blade is stalled (locked rotor), the internal resistance (impedance) prevents the current from rising to a level that would cause the coils to catch fire or melt. * **Insulation Class:** Typically Class B or F, allowing the electronic components to withstand internal temperatures up to 130°C–155°C. #### C. Connection Interface The **"R2"** designation often refers to the termination style: * **Lead Wires:** Usually features two color-coded UL-recognized lead wires (typically black/black or blue/brown) for direct AC input. * **Grounding:** Some variants include a specific grounding lug on the metal housing to prevent Electrostatic Discharge (ESD) or EMI issues. --- ### 4. Mechanical & Material Composition * **Housing:** Die-cast aluminum (acts as a heat sink for the motor electronics). * **Impeller:** Reinforced plastic (PBT) or metal, balanced to reduce electronic noise and vibration. * **Environment:** The "/N" variant is often ruggedized for higher humidity or dust environments. ---
