The **MA14FAG-R** is a specific electronic component typically associated with **Mecatronics** (a fan manufacturer) or similar thermal management solutions. Specifically, it refers to an **Axial Cooling Fan**. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Feature | Description | | :--- | :--- | | **Component Type** | AC Axial Cooling Fan | | **Frame Size** | 120mm x 120mm x 38mm (Standard Industrial Size) | | **Bearing Type** | Ball Bearing (indicated by 'B' or 'G' series variants) | | **Material** | Aluminum Die-Cast Frame; PBT Thermoplastic Impeller | | **Termination** | Terminals (indicated by the 'R' or 'T' suffix) or Lead Wires | ### 2. Electrical Characteristics The "MA" series generally operates on Alternating Current (AC). * **Operating Voltage:** 115V AC (Standard for the 1-series prefix). * **Frequency:** 50/60 Hz. * **Input Power:** Typically ranges between 15W to 20W depending on the specific frequency. * **Protection:** Impedance protected to prevent burnout if the motor is stalled. ### 3. Part Number Breakdown While manufacturer codes vary slightly, the string **MA14FAG-R** generally decodes as follows: | Code Segment | Meaning | | :--- | :--- | | **MA** | Series Designation (AC Fan) | | **1** | Voltage Code (1 = 115V) | | **4** | Size Code (4 = 120mm) | | **F** | Thickness / Performance High-flow variant | | **A** | Bearing Type (Usually Ball Bearing) | | **G** | Speed Grade (G = High Speed) | | **-R** | Termination / Protection (e.g., Terminal connection or RoHS compliant) | ### 4. Key Electronic Features * **Shaded Pole Motor:** This is a simple, robust induction motor used in these fans, requiring no capacitors for starting. * **Dielectric Strength:** Usually rated for 1500 VAC for 1 minute between the frame and terminals. * **Insulation Resistance:** Minimum 100M Ohm at 500 VDC. * **Thermal Protection:** Built-in impedance protection ensures the coils do not catch fire even if the fan blades are obstructed. --- ### 5. Application Areas Because of its high airflow and AC power input, this part is commonly found in: 1. **Server Racks:** To exhaust heat from high-density computing. 2. **Industrial Control Panels:** Cooling PLCs and power supplies. 3. **Power Inverters:** Managing heat generated by large transformers.
