The **RWS600B-15-R** is a 600W single-output AC-DC industrial power supply manufactured by TDK-Lambda. This specific model provides a 15V output and includes a "Remote On/Off" feature (indicated by the `-R` suffix). Below is a breakdown of its electronic specifications and features. --- ### 1. Key Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 85 - 265 VAC (Universal Input) | | **Output Voltage** | 15 VDC | | **Output Current** | 40 A | | **Power Rating** | 600 W | | **Efficiency** | Typical 86% - 89% | | **Cooling** | Internal forced air (Built-in Fan) | --- ### 2. Core Electronic Components & Features #### Input Stage * **Active PFC:** Includes active Power Factor Correction to ensure high efficiency and compliance with harmonic current standards (IEC61000-3-2). * **EMI Filter:** Integrated filtering components to minimize electromagnetic interference. #### Output Control * **Voltage Adjustability:** Features a built-in potentiometer allowing the output to be adjusted typically between **13.5V and 16.5V**. * **Remote On/Off (-R):** This specific version includes additional circuitry that allows the power supply to be toggled on or off using an external electrical signal without cutting the AC main line. #### Protection Circuitry The device contains several internal protection mechanisms to prevent component failure: 1. **Overcurrent Protection (OCP):** Shuts down or limits current if the load exceeds ~105% of the rated capacity. 2. **Overvoltage Protection (OVP):** Protects connected electronics by shutting down if the output voltage spikes (typically 115% - 140%). 3. **Thermal Protection:** Sensors monitor internal temperatures and shut the unit down if it exceeds safe operating limits. --- ### 3. Physical Layout & Terminals The unit is housed in an enclosed metal chassis with the following terminal types: * **Input Terminals:** L (Live), N (Neutral), and FG (Frame Ground) M4 screws. * **Output Terminals:** Heavy-duty M5 screw terminals to handle the high 40A current. * **Signal Connector:** A small header for the Remote On/Off function and Remote Sensing (compensates for voltage drops across long wires). --- ### 4. Reliability Indicators * **Electrolytic Capacitors:** Designed for long life; TDK-Lambda rates this series for high reliability in industrial 24/7 environments. * **Isolation:** 3k VAC Input to Output isolation.
