The **RUSB2AC2MW** is a high-performance **USB Charging Receptacle** manufactured by **Hubbell Wiring Device-Kellems**. It is a commercial-grade wall outlet designed to combine standard AC power with modern USB Type-A and Type-C charging ports. --- ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Number** | RUSB2AC2MW | | **AC Rating** | 15A, 125V AC | | **USB Ports** | 1x USB Type-A, 1x USB Type-C | | **Total USB Output** | 5V DC, 5.0 Amp (Shared) | | **Wiring Type** | Back and Side Wired | | **Style** | Decorator Duplex | | **Color** | Matte White (MW) | --- ## Electronic & Functional Components The "electronic parts" of this device consist of a **Power Conversion Module** integrated behind the standard AC receptacle. Here are the key elements: ### 1. AC-to-DC Rectification Circuit Since the wall outlet provides 125V alternating current (AC), the internal electronics include a step-down transformer and a bridge rectifier. This converts high-voltage AC into a stable, low-voltage direct current (DC) used for USB charging. ### 2. Smart Chip (Power Delivery Logic) The "2AC" designation indicates the presence of a smart controller. This chip: * **Identifies Connected Devices:** Detects whether an iPhone, Android, or tablet is plugged in. * **Optimizes Current:** Distributes the 5.0 Amps efficiently between the Type-A and Type-C ports. * **Protection:** Prevents overcharging, overheating, and short-circuiting. ### 3. USB Type-C Port Unlike the older Type-A ports, the Type-C port in this unit is designed for durability and faster power delivery. It supports the physical Type-C standard, though it is primarily optimized for 5V charging rather than high-voltage USB-PD (Power Delivery) profiles. ### 4. Safety Shutters (Tamper-Resistant) The AC outlets feature internal **Tamper-Resistant (TR) shutters**. These are mechanical electronic-safety parts that prevent foreign objects (like keys or hairpins) from being inserted into the live slots, while allowing standard plugs to enter easily. --- ## Connectivity Diagram ```text [ AC Mains 125V ] | +------> [ AC Outlets (Top/Bottom) ] ----> Standard Appliances | +------> [ Internal DC Transformer ] | +------> [ Smart Controller Chip ] | +--- (Port 1: USB-A) +--- (Port 2: USB-C) ``` ## Key Benefits for Users * **High Output:** 5.0 Amps is significantly higher than standard 2.1A or 3.0A outlets, allowing for faster charging of two tablets simultaneously. * **Space Saving:** Eliminates the need for bulky "wall wart" adapters. * **Green Design:** The unit has extremely low "vampire" power draw when devices are not plugged in.
