The **ZWS240BP-36/R** is a high-reliability, open-frame AC-DC power supply manufactured by **TDK-Lambda**. It is part of the ZWS-BP series, specifically designed to handle high peak loads and offer a long service life. Below is a detailed breakdown of its electronic specifications and features. ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | TDK-Lambda | | **Output Voltage** | 36V DC | | **Output Power (Rated)** | 241.2W | | **Peak Output Power** | 432W (up to 10 seconds) | | **Input Voltage Range** | 85 - 265 VAC (Universal) or 120 - 370 VDC | | **Efficiency** | ~91% (typical at 200VAC) | | **Cooling** | Convection Cooled (No fans required) | | **Suffix "/R"** | Remote ON/OFF Control feature included | --- ### 2. Major Electronic Components & Design The architecture of this power supply focuses on efficiency and thermal management: * **Power Factor Correction (PFC):** It features active PFC, ensuring compliance with EN61000-3-2 standards, which minimizes harmonic current emissions and improves energy efficiency. * **Capacitor Selection:** TDK-Lambda uses high-grade electrolytic capacitors designed for a 10-year lifetime under standard operating conditions (at 40°C, 24h a day). * **Circuit Protection:** * **Overcurrent Protection (OCP):** Constant current limiting with automatic recovery. * **Overvoltage Protection (OVP):** Shuts down the output if the voltage exceeds a safe threshold (approx. 41.4 - 50.4V). * **Remote ON/OFF Control (/R):** The "R" suffix indicates the inclusion of a dedicated circuit that allows the user to toggle the power supply state using an external signal without disconnecting the AC mains. --- ### 3. Application Use Cases Because of its high peak power capability (allowing for nearly double the rated wattage for short bursts), this unit is ideal for: 1. **Motors and Actuators:** Handling the high inrush current required to start mechanical movements. 2. **Industrial Automation:** Powering PLCs and sensors where high reliability is required. 3. **Communication Equipment:** Suitable for noise-sensitive environments due to conducted emission compliance (EN55011/EN55022-B). --- ### 4. Physical Layout The unit is an **Open Frame** design, meaning the internal electronic components (Transformers, MOSFETs, and Heat Sinks) are exposed for maximum airflow. It uses a standard JST connector interface for input and output. ---
