The **W2PE-52G-R2/N** is a specialized power distribution component, typically identified as an **ATS (Automatic Transfer Switch) Power Module** or a specific high-efficiency power supply unit often used in server chassis or networking enclosures (such as those manufactured by Chenbro or similar industrial server rack providers). Below is a breakdown of its electronic characteristics and functional parts. --- ### 1. Key Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Redundant Power Supply Module / ATS Module | | **Max Power Output** | Generally rated around 500W - 520W (varies by sub-revision) | | **Input Type** | AC Universal Input (100V - 240V) | | **Form Factor** | 1U Slim Redundant / Proprietary Module | | **Efficiency Rating** | Typically 80 Plus Gold or Platinum certified | | **Cooling** | Integrated high-RPM 40mm cooling fan | --- ### 2. Core Electronic Components The "R2/N" designation implies a specific revision with the following internal electronic architecture: #### A. Power Conversion Stage * **Active PFC (Power Factor Correction):** Utilizes a dedicated controller and high-voltage inductors to ensure power factor values >0.95, reducing electrical waste. * **PWM Controller:** Manages the switching frequency of the MOSFETs to regulate the DC output voltage precisely under varying loads. #### B. Redundancy & Logic * **Hot-Swap Interface:** The rear of the module features a "Gold Finger" edge connector. This allows the unit to be inserted or removed while the system is running. * **I2C / PMBus Communication:** The unit includes a logic board that communicates with the motherboard (via the backplane) to report fan speed, temperature, and power consumption. #### C. Protection Circuitry The module integrates several protection layers to prevent damage to the server hardware: 1. **OVP (Over Voltage Protection):** Shuts down if the rail exceeds safe limits. 2. **OCP (Over Current Protection):** Prevents traces from melting during a short circuit. 3. **OTP (Over Temperature Protection):** Throttles or shuts down if the internal heatsinks reach critical temperatures. --- ### 3. Connection and Integration | Part | Function | | :--- | :--- | | **AC Inlet** | Standard C14 connector for power input. | | **LED Indicators** | Usually Bi-color (Green/Amber) to indicate Power OK or Fault status. | | **Locking Lever** | Mechanical latch to ensure the module stays seated against the backplane. | | **Backplane Connector** | Transfers +12V, +5Vsb, and GND to the distribution board. | --- ### 4. Typical Applications * **1U/2U Rackmount Servers:** Providing N+1 redundancy. * **Industrial PCs:** Where 24/7 uptime is required. * **Storage Arrays:** Powering high-density HDD/SSD arrays that require stable 12V rails. ---
