The **AM3T-4807S-RZ** is a high-performance DC-DC converter manufactured by **Aimtec**. It is part of the AM3T series, designed to provide regulated output power in a compact package, commonly used in industrial and telecommunications applications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage Range** | 36V to 72V DC (48V Nominal) | | **Output Voltage** | 7.2V DC | | **Output Current** | 416 mA (Max) | | **Power Rating** | 3 Watts | | **Isolation Voltage** | 1500 VDC | | **Efficiency** | ~78% - 82% | | **Package Style** | DIP24 (Plastic case) | --- ### 2. Functional Breakdown #### Input Stage The "48" in the part number indicates a nominal 48V input. Because it features a **2:1 wide input range**, it can handle fluctuations between 36V and 72V. It typically includes internal filters to minimize electromagnetic interference (EMI). #### Isolation & Regulation * **Isolation (1500 VDC):** This part provides galvanic isolation between the input and output circuits, protecting sensitive downstream components from high-voltage surges on the input line. * **Regulated Output:** Unlike unregulated converters, the "S" (Single output) version maintains a stable 7.2V output regardless of load changes or input voltage swings within the specified range. #### Protection Features The device is equipped with several safety mechanisms to prevent damage during circuit failures: * **Continuous Short Circuit Protection:** Automatically recovers once the short is removed. * **Operating Temperature:** Designed to operate in harsh environments, typically ranging from **-40°C to +85°C**. --- ### 3. Pinout Configuration (DIP24) Standard DIP24 DC-DC converters like the AM3T series usually follow this common pin mapping: ```text Pin 2, 3 : -V Input Pin 9 : No Pin / NC Pin 11 : NC (No Connection) Pin 14 : +V Output Pin 16 : -V Output Pin 22, 23 : +V Input ``` --- ### 4. Applications * **Industrial Controls:** Powering sensors and microcontrollers from a 48V factory bus. * **Telecommunications:** Converting standard 48V rail power to logic-level voltages. * **Distributed Power Architectures:** Used as a local "point-of-load" regulator to reduce noise across large PCBs.
