The **W2CE-12D-R/CE** is a high-performance **AC Axial Fan** manufactured by **WIDAL** (commonly associated with San Ace or NMB style industrial cooling solutions). This specific model is designed for thermal management in industrial equipment, server racks, and power supplies. --- ### ## Technical Specifications Below are the core electronic and mechanical parameters for the W2CE-12D-R/CE: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V / 240V AC | | **Frequency** | 50 / 60 Hz | | **Rated Current** | 0.12A - 0.14A (approx.) | | **Power Consumption** | ~18W - 22W | | **Bearing Type** | Dual Ball Bearing | | **Speed (RPM)** | ~2,600 - 3,000 RPM | | **Airflow Capacity** | ~90 - 105 CFM | | **Noise Level** | ~40 - 45 dB(A) | | **Frame Material** | Die-cast Aluminum | --- ### ### Key Electronic Components & Features 1. **Shaded Pole Motor / Capacitor Run Motor:** The internal motor utilizes AC induction technology. It is designed for high reliability and continuous operation (24/7) without the need for brushes that wear out. 2. **Impedance Protection:** The "CE" and "R" designations often indicate built-in **impedance protection**. This prevents the motor from burning out if the fan blades are obstructed (locked rotor) by limiting the current flow. 3. **Dual Ball Bearing System:** Unlike sleeve bearings, the dual ball bearing system allows the fan to be mounted in any orientation (horizontal, vertical, or angled) while maintaining a long service life (typically >50,000 hours). 4. **Terminals vs. Lead Wires:** * **"R" suffix:** Often denotes specific lead-wire configurations or specialized connectors. * **"CE" suffix:** Indicates compliance with European safety standards (Conformité Européenne), ensuring electromagnetic interference (EMI) and safety requirements are met. --- ### ### Wiring Diagram Logic The fan typically operates on a simple two-wire system for AC power: ```markdown [ AC L ] ----------- ( Black / Brown Wire ) | [ FAN ] | [ AC N ] ----------- ( Blue / White Wire ) ``` *Note: Some industrial versions include a third Green/Yellow wire for Earth Grounding to the aluminum frame.* --- ### ### Applications * **Server Cabinets:** Removing heat from dense computing hardware. * **Industrial Control Panels:** Preventing overheating of PLCs and Inverters. * **Medical Equipment:** Quiet but reliable cooling for sensitive electronics.
