The **SWF240P-36-R-T** is a high-efficiency, industrial-grade AC/DC power supply manufactured by **Sanken Electric**. It is part of the SWF series, designed specifically for applications requiring high peak power and compliance with rigorous safety standards. --- ### 1. Key Technical Specifications The following table outlines the core electrical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Output Voltage** | 36V DC | | **Output Current (Rated)** | 6.7A | | **Output Power (Rated)** | 241.2W | | **Peak Power Capability** | Up to 410W (short duration) | | **Input Voltage Range** | 85V to 264V AC (Universal) | | **Efficiency** | ~90% (at 230V AC) | | **Form Factor** | Open Frame / U-Chassis | --- ### 2. Breakdown of the Model Name The part number can be decoded as follows: * **SWF**: Series name (Sanken Switching Power Supply). * **240**: Nominal output wattage (approx. 240W). * **P**: Indicates **Peak Power** capability (useful for motor startup or high-inrush loads). * **36**: Output voltage (36 Volts). * **R**: Remote sensing/Remote ON-OFF functionality (depending on specific sub-configuration). * **T**: Terminal Block type (Connection style). --- ### 3. Core Electronic Features #### A. Power Factor Correction (PFC) The unit includes active PFC circuitry. This ensures that the power factor is close to **0.95–0.99**, minimizing harmonic current distortion and meeting global standards like EN61000-3-2. #### B. Protection Mechanisms To ensure longevity and safety, the unit integrates several protection circuits: 1. **Overcurrent Protection (OCP):** Automatically limits current if the load exceeds the peak rating. 2. **Overvoltage Protection (OVP):** Shuts down the unit if the output voltage rises above a safe threshold (typically ~115%–140%). 3. **Overheat Protection (OHP):** Latches the power supply off if internal temperatures become critical. #### C. Thermal Management The SWF240P is designed for **Convection Cooling**. It does not require a dedicated fan if operated within its rated temperature range and air-flow clearances, though derating may apply depending on the mounting orientation. --- ### 4. Typical Applications * **Industrial Automation:** Powering PLCs, sensors, and actuators. * **Motor Drives:** The "P" (Peak Power) rating makes it ideal for 36V DC motors that require high current during the starting phase. * **Telecommunications:** Used in base stations or networking hardware requiring stable 36V rails. * **LED Signage:** Providing high-efficiency power for large-scale lighting arrays. ---
