### Overview of MGFS302415-R The **MGFS302415-R** is a high-efficiency, isolated DC-DC converter manufactured by **Cosel**. It belongs to the MGFS series, which is known for its compact 1x1 inch footprint and high power density. This specific model is designed for industrial, telecommunications, and battery-powered applications where space and reliability are critical. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Series** | MGFS (Isolated Type) | | **Output Power** | 30 Watts | | **Input Voltage (Nominal)** | 24V DC | | **Input Voltage Range** | 9V to 36V DC (4:1 Wide Range) | | **Output Voltage** | 15V DC | | **Output Current** | 2.0A | | **Efficiency** | ~89% (Typical) | | **Isolation Voltage** | 1,500V DC (1 minute) | | **Package / Case** | 1" x 1" (Through Hole) | | **Operating Temperature** | -40°C to +85°C | --- ### Key Electronic Features 1. **Wide Input Range (4:1):** Unlike standard converters that might only handle a narrow range, this part accepts anything from 9V to 36V. This makes it ideal for 12V or 24V battery systems where voltage fluctuates. 2. **Built-in Protection:** * **Overcurrent Protection (OCP):** Automatically recovers after the fault is removed. * **Overvoltage Protection (OVP):** Protects the load from voltage spikes. * **Thermal Protection:** Shuts down the unit if the internal temperature exceeds safety limits. 3. **Synchronous Rectification:** The device utilizes synchronous rectification circuits to minimize power loss, allowing it to achieve 30W of output in a very small physical footprint without needing a massive heatsink. 4. **Remote ON/OFF:** Includes a dedicated pin to control the output state (Enabled/Disabled) without needing to disconnect the main input power. 5. **Adjustable Output Voltage (TRM):** By connecting an external resistor to the "TRM" (Trim) pin, the output voltage can be adjusted slightly (typically ±10%) to account for voltage drops across long cables. --- ### Pin Configuration (Standard 1x1 Design) ```text [TOP VIEW] +-------------------+ | 1: +Vin 6: +Vout| | | | 2: -Vin 5: TRM | | | | 3: RC 4: -Vout| +-------------------+ ``` * **RC (Remote Control):** Controls the power supply state. * **TRM (Trim):** Used for output voltage adjustment. --- ### Typical Applications * **Industrial Automation:** Powering PLCs or sensors from a fluctuating 24V factory rail. * **Test & Measurement:** Providing stable 15V rails for analog circuitry. * **Telecommunications:** Wide input range handles varied battery backup voltages.
