The **RTD-2424-R** is a high-performance DC/DC converter belonging to the **RTD series** manufactured by RECOM Power. This component is specifically designed for industrial applications requiring isolated dual outputs with high efficiency. --- ### 1. Key Technical Specifications The following table highlights the core electrical characteristics of the RTD-2424-R: | Feature | Specification | | :--- | :--- | | **Input Voltage (Nominal)** | 24V DC | | **Input Voltage Range** | 21.6V – 26.4V DC | | **Output Voltage 1** | +24V DC | | **Output Voltage 2** | -24V DC | | **Output Current** | ±42mA | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 1kV DC (Standard) | | **Efficiency** | 80% - 85% (Typical) | | **Package Type** | DIP14 (Dual In-line Package) | --- ### 2. Functional Description The RTD-2424-R serves as an **isolated, unregulated dual-output converter**. Here is a breakdown of its internal electronic behavior: * **Galvanic Isolation:** It provides physical and electrical separation between the input and output stages. This is crucial for breaking ground loops and protecting sensitive logic circuitry from noise generated on the 24V supply line. * **Dual Rail Generation:** It converts a single 24V input into a symmetrical +/- 24V output. This is commonly required for powering operational amplifiers (Op-Amps) or specialized sensors that require a split-rail power supply. * **Unregulated Architecture:** The "R" in the series often denotes a specific pinout or efficiency rating. As an unregulated converter, the output voltage may fluctuate slightly depending on the load; therefore, it is best used with a stable input and a relatively constant load. --- ### 3. Pin Configuration (DIP14) While always refer to the specific manufacturer datasheet before PCB layout, the standard pinout for this series is typically: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | -Vin | Negative Input Voltage | | 7 | NC | No Connection | | 8 | Com | Common (0V Output) | | 9 | +Vout | Positive Output (+24V) | | 11 | -Vout | Negative Output (-24V) | | 14 | +Vin | Positive Input Voltage (+24V) | --- ### 4. Typical Applications * **Industrial Automation:** Powering analog signal conditioners. * **Data Acquisition:** Providing bipolar power for high-precision ADCs. * **Telecommunications:** Localized voltage conversion for line drivers. * **Test & Measurement:** Creating isolated split-rails for laboratory equipment.
