The **W2TG0-124-R2/UL** is a high-performance **AC Axial Fan** manufactured by **ebm-papst**. This specific model belongs to the S-Series and is designed for industrial cooling applications requiring reliability and high airflow in a compact form factor. --- ### ## Technical Specifications Below are the primary electronic and mechanical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Nominal Voltage** | 115 VAC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | 22 W (at 60Hz) / 24 W (at 50Hz) | | **Speed (RPM)** | 2700 - 3050 RPM | | **Airflow** | ~100 CFM (170 m³/h) | | **Bearing Type** | Ball Bearing | | **Noise Level** | 44 - 48 dB(A) | | **Termination** | 2-Terminals (Plug-in) | | **Weight** | 0.8 kg (Approx.) | --- ### ## Key Electronic Components & Features #### 1. Motor Technology The unit utilizes a **shaded-pole motor**. These motors are rugged and reliable for AC applications because they do not require start capacitors, reducing the number of failure points in the circuit. It is impedance-protected against overloading. #### 2. Environmental Protection The "UL" suffix indicates that the part is **Underwriters Laboratories (UL) recognized**. The insulation system is typically Class B or F, allowing it to operate in temperatures up to 70°C without electronic failure. #### 3. Housing and Impeller * **Housing:** Die-cast aluminum, providing excellent heat dissipation for the internal motor windings and grounding for EMI reduction. * **Impeller:** Sheet steel, directly welded onto the rotor (external rotor motor design), which allows for a very compact axial depth. --- ### ## Connection Schematic (Typical) While the device uses a standard AC plug-in terminal, the internal wiring logic follows this standard structure: ```mermaid graph LR A[AC Line - 115V] --> B[Terminal 1] C[AC Neutral] --> D[Terminal 2] E[Metal Frame] --> F[Earth Ground] ``` *Note: Always ensure the metal frame is grounded to the chassis to prevent electrostatic buildup or shock hazards.* ---
