The **W2SP-2B3-R2** is a specific part number typically associated with high-performance power modules, often used in telecommunications, server infrastructure, or industrial power supplies. Based on its nomenclature, it belongs to a category of **Hot-Swappable Power Supplies** or **PDU (Power Distribution Unit)** components. --- ### 1. General Specifications While specific datasheets can vary by manufacturer (often associated with brands like Delta or specialized power vendors), the "W2SP" series generally adheres to these specifications: | Feature | Description | | :--- | :--- | | **Component Type** | AC-DC Power Supply Module | | **Input Type** | Universal AC Input (100V - 240V) | | **Form Factor** | 1U or Slim-line Rack Mount | | **Cooling** | Internal high-speed DC Fan | | **Hot-Swap** | Supported (Redundant configuration) | --- ### 2. Key Electronic Features The "2B3-R2" suffix usually denotes the revision and specific output tuning. * **Redundancy (N+1):** This part is designed to work in parallel with another identical unit. If one fails, the other takes the full load without downtime. * **Active PFC (Power Factor Correction):** It includes internal circuitry to ensure the power factor is close to 1.0, reducing electrical waste and heat. * **Protection Circuits:** * **OVP:** Over Voltage Protection. * **OCP:** Over Current Protection. * **SCP:** Short Circuit Protection. * **OTP:** Over Temperature Protection. * **Communication Interface:** Usually features an **I2C or PMBus** interface, allowing the system motherboard to monitor temperature, fan speed, and power consumption in real-time. --- ### 3. Connection Pinout (Typical) The rear of the module usually features a "Gold Finger" or "Blade" connector instead of standard wires. | Pin Section | Function | | :--- | :--- | | **Power Blades** | Main DC Output (e.g., +12V or +54V) | | **Return/GND** | Common Ground for high current | | **Signal Pins** | PS_ON, PW_OK, I2C Clock (SCL), I2C Data (SDA) | --- ### 4. Common Applications * **Data Centers:** Powering blade servers and high-density storage arrays. * **Telecommunications:** 5G base stations and network switching hubs. * **Industrial Automation:** High-reliability PLC control cabinets.
