The **PDU-AN2N-R** is a specific Power Distribution Unit (PDU) model, typically associated with networking and server rack environments. Below is a breakdown of its electronic components, specifications, and design features. --- ## 1. Core Technical Specifications The "AN2N" series generally refers to basic or metered PDUs designed for high-density power distribution. | Feature | Description | | :--- | :--- | | **Input Voltage** | Typically 100-240V AC (Auto-sensing) | | **Current Rating** | Usually 16A or 32A depending on the regional plug | | **Input Plug** | Often IEC-320 C20 or NEMA L6-20P | | **Output Receptacles** | A mix of IEC C13 (10A) and IEC C19 (16A) outlets | | **Form Factor** | 0U (Vertical Mount) or 1U/2U (Horizontal) | --- ## 2. Key Electronic Components ### A. Internal Circuitry * **Busbar System:** Unlike standard power strips that use wires, professional PDUs like the AN2N-R use solid copper busbars. This reduces heat generation and improves conductivity for high-amperage loads. * **Circuit Breakers:** Integrated thermal-magnetic breakers protect against overloads. The "-R" suffix often indicates a **Resettable** breaker or a **Redundant** configuration. ### B. Monitoring Module (Metered Models) If the unit is a "Metered" version, it contains: * **LED Display:** A 3-digit or 4-digit 7-segment display showing real-time Amperage (A). * **Current Transformer (CT):** An internal sensor that wraps around the main input line to measure current draw without breaking the circuit. ### C. Physical Construction * **Chassis:** All-metal (Aluminum or Cold-rolled Steel) to provide grounding and electromagnetic interference (EMI) shielding. * **Socket Material:** High-temperature resistant thermoplastic to prevent melting during sustained high-load operations. --- ## 3. The "-R" Suffix Meaning In the context of PDU-AN2N-R, the "R" usually signifies specific electronic or physical orientations: 1. **Rackmount/Rear:** Designed for specific mounting at the rear of the cabinet. 2. **Redundancy:** Dual-circuit input in some specialized models. 3. **RoHS Compliant:** Ensuring the electronic solder and components are lead-free. --- ## 4. Wiring Diagram Concept Internally, the wiring follows a standard parallel distribution to ensure that if one device fails, the others remain powered. ```mermaid graph LR Input[AC Input 240V] --> CB[Circuit Breaker] CB --> Meter[Amperage Meter] Meter --> Busbar[Copper Busbar] Busbar --> Outlet1[C13 Outlet] Busbar --> Outlet2[C13 Outlet] Busbar --> Outlet3[C19 Outlet] ```
