The **W2TS-0AB-R/N** is a specific part number typically associated with high-performance **Cooling Fans**, specifically those manufactured by **Nidec** (or distributed through specific industrial channels). These fans are designed for high-density servers, telecommunications equipment, and industrial enclosures. Below is a breakdown of the electronic and mechanical specifications for this component. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | DC Axial Fan | | **Manufacturer** | Nidec (commonly used in Delta/San Ace compatible slots) | | **Typical Voltage** | 12V DC | | **Frame Size** | 40mm x 40mm x 28mm (Common server size) | | **Bearing Type** | Dual Ball Bearing (for long life and high heat resistance) | --- ### 2. Electronic Interface & Wiring The "R/N" suffix usually denotes a specific wiring configuration involving feedback signals. * **PWM Control:** Most fans in this series utilize Pulse Width Modulation (PWM) to allow the motherboard or controller to dynamically adjust fan speed based on thermal demand. * **Tachometer (FG) Signal:** Includes a frequency generator output (usually a yellow or white wire) that sends a signal to the system to monitor the actual RPM. * **Safety Features:** * **Locked Rotor Protection:** Automatically shuts off or reduces power if the blades are obstructed to prevent motor burnout. * **Reverse Polarity Protection:** Prevents damage if the positive and negative leads are accidentally swapped. --- ### 3. Key Performance Attributes The W2TS series is engineered for **High Static Pressure**, which is critical for pushing air through tightly packed electronic components (like heat sinks or HDD cages). 1. **High RPM:** These fans often operate between 15,000 to 25,000 RPM. 2. **Airflow vs. Pressure:** Designed to maintain airflow even when the system resistance (impedance) is high. 3. **Durability:** Rated for "L10" life expectancy (usually 70,000+ hours at 40°C). --- ### 4. Part Number Breakdown (Nidec Format) While exact internal coding varies, the nomenclature usually follows this logic: | Segment | Meaning | | :--- | :--- | | **W2** | Series designation (Blade/Motor geometry) | | **TS** | High-speed / High-pressure variant | | **0AB** | Specific electrical Revision/Voltage code | | **R/N** | Connector/Signal type (e.g., Red/Black/Blue/Yellow wiring) | --- ### 5. Common Applications * **1U/2U Servers:** Used in the mid-chassis fan wall. * **Network Switches:** Cooling high-speed ASICs. * **Power Supplies:** Internal cooling for high-wattage PSU units.
