The **MAH24FAX-R** is a specific model of an AC axial fan, typically manufactured by companies like **Fulltech Electric**. These fans are designed for industrial cooling applications where high airflow and reliability are required. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications The "MAH24FAX-R" designation usually refers to a 240mm class high-performance fan. | Parameter | Typical Value | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (PBT) or Metal | | **Termination** | Lead Wires or Terminal Blocks | | **Protection** | Impedance Protected or Thermal Protected | --- ### 2. Key Electronic Components The fan operates using an **AC Induction Motor** (External Rotor Motor). Here are the core electronic aspects: * **Stator Windings:** Copper coils treated with Class B or Class F insulation to withstand high operating temperatures. * **Capacitor-Run Motor:** Many fans in this size category use a permanent split capacitor (PSC) motor to improve electrical efficiency and starting torque. * **Thermal Protection:** Includes an internal thermal cutout (auto-reset) that disconnects power if the motor temperature exceeds safe limits (usually around 110°C - 130°C). * **EMI Filtering:** Often includes basic shielding or internal design considerations to minimize electromagnetic interference with surrounding industrial equipment. --- ### 3. Performance Characteristics | Feature | Description | | :--- | :--- | | **Airflow Direction** | Exhaust (Over struts) or Intake | | **Speed Control** | Generally fixed speed, though can be controlled via AC voltage regulators (Triac-based). | | **Durability** | Rated for 50,000+ hours of continuous operation at 25°C. | | **IP Rating** | Typically IP44 or IP54 (Dust and splash resistance). | --- ### 4. Wiring Diagram (Standard AC) Most models utilize a simple two-wire or three-wire (including Ground) setup: ```markdown L (Line) -----> [ Black Wire ] N (Neutral) -----> [ Blue/White Wire ] G (Ground) -----> [ Green/Yellow Wire ] ``` ---
