The **W2AC-A23D-R/N** belongs to the **W2 series** of industrial fan controllers and AC axial fan assemblies, typically manufactured by brands like **Oriental Motor**. This specific model refers to a high-performance cooling solution designed for industrial equipment cabinets and machinery. --- ## Technical Specifications The following table outlines the primary electronic and mechanical characteristics of the W2AC-A23D-R/N: | Feature | Specification | | :--- | :--- | | **Voltage** | Single-Phase 230V AC | | **Frequency** | 50 / 60 Hz | | **Power Input** | ~14W to 16W (varies by load) | | **Current Rating** | ~0.10A to 0.12A | | **Speed (RPM)** | 2700 - 3200 RPM | | **Airflow Capacity** | Approx. 35 - 42 CFM | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Lead Wires (R/N suffix often indicates specific wiring/plug types) | --- ## Key Electronic Components ### 1. Shaded Pole Motor The heart of this unit is a shaded pole induction motor. These are favored in industrial fans for their: * **Reliability:** No brushes to wear out. * **Simplicity:** Does not require a starting capacitor (though some high-torque variants do). * **Stall Protection:** Impedance protected, meaning it won't catch fire if the blades are physically obstructed. ### 2. Insulation and Protection * **Class B Insulation:** Rated to handle internal temperatures up to 130°C. * **Impedance Protection:** The motor is designed so that the resistance of the windings limits the current flow even if the motor is stalled, preventing electronic failure. ### 3. Integrated Circuitry (Alarm Models) If this specific variant includes the **"R/N" Low-Speed Alarm** feature: * It contains an internal sensor (Hall Effect or Inductive) that monitors the rotation. * If the RPM drops below a factory-set threshold, the "R/N" circuit triggers an output signal to alert the PLC or system controller of a cooling failure. --- ## Wiring Logic The unit typically uses a 2-wire or 3-wire configuration depending on the alarm feature: ```markdown L (Line) -----> [ Brown or Black ] N (Neutral) -----> [ Blue or White ] G (Ground) -----> [ Green/Yellow ] (Usually on the metal frame) ``` ### Environmental Durability The electronic parts are encased in a die-cast aluminum frame to act as a heat sink, while the blades are usually made of polybutylene terephthalate (PBT) resin, which is non-conductive and flame-retardant.
