Key Technical Specifications The model name contains specific data about its electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 18V - 76V DC (Standard 48V Input) | | **Output Voltage** | 3.3V DC | | **Output Current** | 4.5 A | | **Rated Wattage** | 14.85 W (Approx. 15W class) | | **Efficiency** | ~88% | | **Package / Case** | Six-sided shielded metal case (1x1 inch) | --- ### 2. Main Features and Functions * **Wide Input Range (4:1):** This part accepts a broad range of input voltages (18V to 76V), making it suitable for systems where battery levels or power supplies might fluctuate. * **Isolation:** It provides 1,500V DC isolation between the input and output, which protects sensitive downstream electronics from surges or noise on the primary power rail. * **Built-in Protections:** * **Overcurrent Protection (OCP):** Automatically recovers when the fault is removed. * **Overvoltage Protection (OVP):** Protects the load from voltage spikes. * **Thermal Protection:** Shuts down the device if internal temperatures exceed safety limits. * **Remote ON/OFF:** Allows the system to control the power state of the converter electronically without a physical switch. * **Voltage Trimming:** Users can adjust the output voltage slightly (typically ±10%) using an external resistor. --- ### 3. Physical Layout and Mounting The part is designed for PCB (Printed Circuit Board) mounting. ```markdown Pin Configuration (Simplified): 1. +VIN (Input Power) 2. -VIN (Input Ground) 3. RC (Remote Control) 4. +VOUT (Output Power) 5. -VOUT (Output Ground) 6. TRM (Output Voltage Adjustment) ``` --- ### 4. Common Applications Due to its reliability and wide input range, the MGFS15483R3-R is commonly found in: * **Telecommunications:** Equipment requiring 48V bus power. * **Industrial Automation:** Control systems and sensors. * **Medical Electronics:** Where isolation and stability are critical. * **Battery-Powered Systems:** Dealing with varying discharge voltages.
