The **RTD-2412-R** is a high-performance, isolated DC/DC converter manufactured by **RECOM Power**. It belongs to the RTD series, which is specifically designed for industrial applications requiring dual output voltages and high isolation. ### 1. Key Technical Specifications The following table outlines the primary electrical characteristics of the RTD-2412-R: | Parameter | Value | | :--- | :--- | | **Input Voltage (Nominal)** | 24V DC | | **Input Voltage Range** | 21.6V to 26.4V DC | | **Output Voltage** | ±12V DC (Dual Output) | | **Output Current** | ±84mA | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 1kV DC (standard) | | **Efficiency** | 80% - 84% (Typical) | | **Package Type** | DIP14 (Dual In-line Package) | --- ### 2. Functional Components and Design The RTD-2412-R is composed of several internal electronic stages to ensure stable power delivery: * **Input Filter:** Typically consists of a small internal capacitor to reduce reflected ripple current. * **Switching Topology:** Uses a high-frequency push-pull or Royer oscillator circuit to convert the DC input into an AC signal for transformer coupling. * **Isolation Transformer:** Provides the 1kV DC galvanic isolation between the input and output circuits, protecting sensitive downstream components from input surges. * **Rectification & Smoothing:** Internal Schottky diodes and output capacitors convert the AC back into stable ±12V DC. --- ### 3. Pin Configuration (DIP14) The device uses a standard pinout to facilitate easy PCB integration: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | -Vin | Negative Input Voltage | | 7 | NC | No Connection | | 8 | Com | Common (Ground) for Output | | 9 | +Vout | Positive 12V Output | | 11 | -Vout | Negative 12V Output | | 14 | +Vin | Positive Input Voltage | --- ### 4. Application Use Cases Because this part provides **dual rail outputs (±12V)**, it is primarily used for: 1. **Operational Amplifiers (Op-Amps):** Providing the positive and negative supply rails required for precision analog signal processing. 2. **Sensor Interfaces:** Powering sensors that require symmetrical voltages to measure bipolar signals. 3. **Industrial Automation:** Breaking ground loops in complex control systems to prevent noise interference. ---
