The **AFB0612VHB-R00** is a high-performance DC axial fan manufactured by **Delta Electronics**. It belongs to the AFB series, which is known for its balance of high airflow and reliability. --- ### ## Technical Specifications Below are the primary electrical and mechanical characteristics of the unit: | Parameter | Specification | | :--- | :--- | | **Rated Voltage** | 12V DC | | **Operating Voltage Range** | 7.0V to 13.8V DC | | **Rated Current** | 0.16A (Max 0.24A) | | **Rated Power Input** | 1.92W | | **Speed** | 4500 RPM | | **Maximum Air Flow** | 22.78 CFM (0.645 m³/min) | | **Maximum Air Pressure** | 5.38 mmH₂O | | **Acoustic Noise** | 35.0 dB-A | | **Bearing Type** | Two Ball Bearing | | **Weight** | 80.0 grams | --- ### ### Electronic Components & Internal Features #### 1. Motor Design The fan utilizes a **Brushless DC (BLDC)** motor. Unlike brushed motors, these use an electronic controller to switch the current in the motor windings, reducing mechanical wear and electromagnetic interference (EMI). #### 2. The "-R00" Suffix (Sensor Output) The "R00" designation is critical for the electronic interface. It signifies a **Locked Rotor Sensor (Failure Alarm)**: * **Function:** It provides a signal output that indicates whether the fan is running or stalled. * **Signal Type:** Typically an "Open Collector" output. * **Behavior:** Under normal operation, the signal stays at a low voltage level. If the fan blades are obstructed and the rotor stops, the signal goes "High," alerting the system controller to a cooling failure. #### 3. Protection Circuitry The internal PCB includes several protective features to prevent electronic damage: * **Polarity Protection:** Prevents damage if the positive and negative leads are reversed. * **Locked Rotor Protection:** Automatically cuts or limits power to the coils if the fan is physically stuck, preventing the motor from overheating and burning out. --- ### ### Wire Configuration This model typically features a 3-wire lead wire interface: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Red** | **+ VDC** | Positive power supply (12V). | | **Black** | **GND** | Ground / Negative terminal. | | **Blue (or White)** | **RD Signal** | The "R00" Lock Detection signal. | --- ### ### Materials and Durability * **Frame/Impeller:** Plastic (UL 94V-0), which is flame retardant. * **Bearing System:** The **Dual Ball Bearing** system is electronically superior for longevity, offering a life expectancy (L10) of approximately 70,000 hours at 40°C.
