Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Output Power** | 3 Watts | | **Input Voltage Range** | 36V to 72V DC (48V Nominal) | | **Output Voltage** | Dual ±7.2V DC | | **Output Current** | ±208 mA | | **Isolation Voltage** | 1500 VDC | | **Package Style** | DIP24 (Plastic or Metal) | | **Efficiency** | ~78% to 82% | --- ### 2. Breakdown of the Model Name To understand the electronic characteristics, we can decode the part number: * **AM3T**: Series name (3 Watt regulated DC-DC converter). * **48**: Nominal input voltage (48V). It features a 2:1 input range (36-72V). * **07**: Primary output voltage (7.2V). * **D**: **Dual** output. It provides both +7.2V and -7.2V relative to a common ground. * **RZ**: Package/Pinout configuration (Standard DIP24 layout). --- ### 3. Core Electronic Features #### A. Galvanic Isolation This part provides **1500 VDC isolation** between the input and output stages. This is critical for breaking ground loops and protecting sensitive control logic from high-voltage noise or surges on the power rail. #### B. Regulation & Protection Unlike "fixed" converters, the AM3T-4807D-RZ is **fully regulated**. * **Line Regulation:** Maintains stable output despite fluctuations in input voltage. * **Load Regulation:** Maintains stable output despite changes in the current draw. * **Short Circuit Protection:** Continuous protection with auto-recovery to prevent component burnout during faults. #### C. Filtering The device typically includes an internal **Pi-filter** on the input side to reduce reflected ripple current, minimizing electromagnetic interference (EMI) with other components on the PCB. --- ### 4. Typical Applications * **Industrial Controls:** Powering dual-rail operational amplifiers (Op-Amps) that require symmetric positive and negative voltages. * **Telecommunications:** 48V is the standard rail in telecom; this part converts that rail down to usable logic/analog levels. * **Instrumentation:** Providing clean, isolated power to sensors and data acquisition circuits.
