The **SWF240P-36-R** is a high-performance, industrial-grade AC-DC switching power supply manufactured by **Sanken Electric**. It is specifically designed to provide high peak power capabilities, making it ideal for motor-driven applications or systems with high inductive loads. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the SWF240P-36-R: | Parameter | Specification | | :--- | :--- | | **Output Voltage** | 36V DC | | **Output Power (Rated)** | 240W | | **Peak Output Power** | 450W (Approx. 187% of rated) | | **Input Voltage Range** | 85V AC to 264V AC | | **Output Current (Rated)** | 6.7A | | **Peak Current** | 12.5A | | **Efficiency** | ~91% (at 230V AC) | | **Cooling** | Convection Cooled (No fan required) | | **Form Factor** | Open Frame / U-Chassis | --- ## 2. Key Electronic Features ### A. Power Factor Correction (PFC) The unit includes an active PFC circuit. This ensures that the power factor is high (typically >0.95), reducing harmonic distortion and ensuring compliance with international standards like **IEC61000-3-2**. ### B. High Peak Power Capability Unlike standard power supplies that trip during a momentary surge, the "P" in the part number signifies **Peak power**. It can handle up to **450W** for short durations. This is essential for: * Starting DC motors. * Actuating solenoids. * Powering printers during paper feed cycles. ### C. Protection Circuitry The device is built with several layers of electronic protection to prevent damage to the load or the supply itself: 1. **Overcurrent Protection (OCP):** Automatically limits current during overload. 2. **Overvoltage Protection (OVP):** Shuts down the output if the voltage exceeds safety limits. 3. **Thermal Protection:** Reduces output or shuts down if the internal temperature exceeds safe operating limits. --- ## 3. Physical Interface and Dimensions ### Connection Ports * **Input (CN1):** 3-pin connector (Line, Neutral, Ground). * **Output (CN2):** Multi-pin connector for 36V DC output. * **Remote Sensing/Control:** Available on specific variants to compensate for voltage drops across long cables. ### Dimensions | Length | Width | Height | | :--- | :--- | :--- | | 190 mm | 84 mm | 44 mm | --- ## 4. Typical Applications * **Industrial Automation:** Powering PLCs and small robotic arms. * **Medical Equipment:** High-reliability power for diagnostic tools. * **Telecommunications:** Base station power modules. * **Office Equipment:** Large-scale commercial printers and scanners.
