The **MEH56ZAG-R** is a specific model of an **AC Axial Fan**, typically manufactured by companies like **Fulltech Electric**. These fans are engineered for industrial cooling, ventilation, and heat dissipation in electronic enclosures. --- ### 1. Technical Specifications Below are the primary electronic and mechanical specifications for this component: | Feature | Specification | | :--- | :--- | | **Motor Type** | External Rotor Capacitor-Run Induction Motor | | **Rated Voltage** | 230V AC (Single Phase) | | **Frequency** | 50 / 60 Hz | | **Input Power** | ~40W to 60W (Varies by load) | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Die-cast Aluminum | | **Impeller Material** | Plastic (PBT) or Metal (depending on sub-version) | | **Termination** | Lead Wires or Terminals | --- ### 2. Key Electronic Components & Features The "MEH" series utilizes several critical internal components to ensure efficiency and safety: * **Capacitor-Run Motor:** Unlike simple shaded-pole motors, this fan uses a run capacitor to create a phase shift in the windings. This results in higher torque and better energy efficiency. * **Thermal Protection:** Most units in this series include an **Impedance Protected** or **Thermal Cut-off** mechanism to prevent the motor from burning out if the blades are obstructed (locked rotor). * **Insulation Class:** Typically rated as **Class B or F**, allowing the internal wiring to withstand temperatures between 130°C and 155°C. * **Dual Ball Bearings:** These are used to ensure a long lifespan (typically 50,000+ hours) and allow the fan to be mounted in any orientation (horizontal or vertical). --- ### 3. Wiring Configuration The fan usually operates on a simple 2-wire or 3-wire (including ground) configuration for AC power. ```yaml Wiring Guide: - Black/Brown: Line (L) - Blue: Neutral (N) - Green/Yellow: Ground (GND) ``` --- ### 4. Applications The MEH56ZAG-R is commonly found in: 1. **Server Racks:** High-volume air displacement for cooling blades. 2. **Industrial Control Panels:** Preventing overheating of PLCs and Inverters. 3. **Power Supplies:** Large-scale AC/DC converters. 4. **HVAC Equipment:** Small-scale ventilation in air handling units.
