The **W2AC-AB1A-R/N** is a specific model within the **W2 Series** of Industrial Power Supply units, typically manufactured by companies like **SolaHD** (Emerson) or similar industrial electronics providers. It is a DIN-rail mounted, AC-DC power converter designed for harsh industrial environments. --- ### 1. Key Technical Specifications The following table outlines the core electronic parameters for this specific part: | Feature | Specification | | :--- | :--- | | **Input Voltage Range** | 100–240 VAC (Universal Input) | | **Output Voltage** | 12 VDC or 24 VDC (Model dependent, typically 24V for 'A' variants) | | **Current Rating** | High efficiency output (refer to specific wattage label) | | **Mounting Type** | DIN Rail (TS35/7.5 or 15) | | **Case Material** | Rugged Industrial Plastic or Aluminum | | **Operating Temperature** | -25°C to +60°C (without derating) | --- ### 2. Breakdown of the Part Number Logic While manufacturers vary slightly, the "W2" series nomenclature usually breaks down as follows: * **W2**: The Series designation (Next-generation compact industrial power). * **AC**: Input type (Alternating Current). * **AB1A**: Internal configuration code (Specific to output wattage and terminal block style). * **R/N**: * **R**: Often indicates **Relay Contact** (Dry contact for "DC OK" signaling). * **N**: Often indicates **Narrow** profile or specific noise filtering standards. --- ### 3. Electronic Protection Features This component includes several integrated circuits and protection layers to safeguard downstream industrial equipment: 1. **Overload Protection:** Uses a "Hiccup mode" or constant current limiting to prevent damage during short circuits. 2. **Overvoltage Protection (OVP):** Internal Zener diode or clamping circuit to prevent high voltage spikes from reaching the PLC or Sensors. 3. **EMI/EMC Filtering:** Built-in Pi-filters to reduce electromagnetic interference, ensuring compliance with EN61000 standards. 4. **Isolation:** High dielectric strength (typically 3kV AC) between input and output stages to prevent ground loops. --- ### 4. Applications The W2AC-AB1A-R/N is commonly found in: * **Control Panels:** Powering PLCs (Programmable Logic Controllers). * **HMI Screens:** Providing stable DC power to operator interfaces. * **Industrial Automation:** Powering sensors, solenoids, and actuators.
