Key Technical Specifications The following table outlines the primary electrical characteristics of the AM3T-4807D-RVZ: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 18V to 72V DC (48V Nominal) | | **Output Voltage** | ±7.2V DC (Dual Output) | | **Output Current** | ±200 mA | | **Max Power** | 3 Watts | | **Isolation Voltage** | 6000 VDC | | **Efficiency** | ~78% - 82% | | **Package Style** | DIP24 (Plastic case) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Core Functional Components The internal architecture of this module consists of several critical electronic stages: 1. **Input Filter:** Includes an internal capacitor and often a Pi-filter arrangement to minimize reflected ripple current back to the primary power source. 2. **Switching Controller:** Uses Pulse Width Modulation (PWM) to convert the DC input into high-frequency AC. 3. **Isolation Transformer:** The "R" in the part number often signifies reinforced isolation. This component provides the 6000VDC galvanic barrier between the input and output. 4. **Rectification & Smoothing:** Fast-recovery diodes and low-ESR capacitors convert the high-frequency AC back into stable DC outputs. 5. **Dual Output Regulation:** The "D" signifies a dual output, meaning it provides both positive (+7.2V) and negative (-7.2V) rails relative to a common ground. --- ### 3.
