The **SWF150P-36-LC-R** is a high-reliability, AC-DC switching power supply manufactured by **Sanken Electric**. It is designed for industrial applications requiring a compact footprint and stable 36V DC output. --- ### ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 85V AC to 264V AC (Universal) | | **Output Voltage** | 36V DC | | **Rated Output Current** | 4.2A (Peak up to 6.3A) | | **Rated Output Power** | 151.2W | | **Efficiency** | ~88% to 91% (typical) | | **Form Factor** | Open Frame (LC denotes "with Chassis/Cover") | | **Dimensions** | Approx. 75 × 35 × 160 mm | --- ### ### Key Features and Components 1. **Power Factor Correction (PFC):** The unit includes active PFC circuitry to comply with harmonic current standards (IEC61000-3-2). This reduces electrical noise and improves energy efficiency. 2. **Peak Load Capability:** Unlike standard power supplies, the "P" series is designed to handle **peak currents** (up to 150% of the rated current). This is essential for components with high startup inrush, such as motors or actuators. 3. **Suffix Breakdown:** * **36**: Indicates the nominal output voltage (36V). * **LC**: Indicates the physical configuration—specifically, it comes with a **L-shaped chassis and a cover**. * **R**: Generally indicates a remote ON/OFF control function or specific connector orientation depending on the sub-revision. 4. **Protection Circuits:** * **Overcurrent Protection (OCP):** Automatically recovers after the fault is removed. * **Overvoltage Protection (OVP):** Shuts down the unit to prevent damage to the load. * **Thermal Protection:** Shuts down if the internal temperature exceeds safety limits. --- ### ### Common Applications * **Industrial Automation:** Powering PLCs, sensors, and small DC motors. * **Telecommunications:** Reliable power for networking hardware. * **Medical Equipment:** Due to high stability and low leakage characteristics (though specific medical certification should be verified per model). * **LED Signage:** Constant voltage supply for high-power LED arrays. --- ### ### Installation Notes * **Derating:** The output power may need to be derated based on the ambient temperature and the orientation of the unit (airflow is critical). * **Grounding:** Ensure the FG (Frame Ground) terminal is connected to the earth to minimize EMI (Electromagnetic Interference).
