Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage Range** | 18V to 36V DC (24V Nominal) | | **Output Voltage** | ±3.3V DC (Dual Output) | | **Output Current** | ±450mA | | **Max Power** | 3 Watts | | **Isolation Voltage** | 1500 VDC | | **Package Style** | DIP24 (Dual In-line Package) | | **Efficiency** | ~72% - 75% | --- ### 2. Breakdown of the Model Name (Part Numbering) Understanding the suffix codes helps identify the specific electronic characteristics: * **AM3T**: Series name (3 Watt, Wide Input Range). * **24**: Nominal Input Voltage (24V). * **03**: Output Voltage (3.3V). * **D**: Dual Output (Produces both +3.3V and -3.3V relative to a common ground). * **RZ**: Package type and specific revision (DIP24 plastic case). --- ### 3. Core Electronic Features #### Dual Output Configuration Unlike standard converters that provide a single positive rail, this unit provides **symmetrical outputs** (±3.3V). This is essential for powering: * Operational Amplifiers (Op-Amps). * High-precision Analog-to-Digital Converters (ADCs). * Audio processing circuits. #### Galvanic Isolation The device provides **1500 VDC isolation** between the input and output stages. This protects sensitive downstream components from input-side voltage spikes and breaks ground loops that can cause electrical noise. #### Protection Circuitry The module includes built-in safety features to prevent failure during fault conditions: 1. **Continuous Short Circuit Protection:** Automatically recovers once the short is removed. 2. **Input Filter:** Typically uses a Pi ($\pi$) filter to minimize reflected ripple current. --- ### 4. Typical Pinout Configuration (DIP24) | Pin Number | Function | Description | | :--- | :--- | :--- | | 2, 3 | -V Input | Negative Supply Input | | 9 | Common | Common Ground for Outputs | | 11 | -V Output | -3.3V Output Rail | | 14 | +V Output | +3.3V Output Rail | | 16 | Common | Common Ground for Outputs | | 22, 23 | +V Input | Positive Supply Input | --- ### 5. Application Areas * **Industrial Controls:** Powering sensors and transducers requiring dual-rail supplies. * **Instrumentation:** Measurement equipment where low-noise isolated power is critical. * **Telecommunications:** Distributed power architectures.
