The **RTD-0505/P-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 isolated outputs from a single input. --- ### 1. Technical Specifications Below are the primary electronic characteristics of the RTD-0505/P-R: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 5V DC (Nominal) | | **Output Voltage** | ±5V DC (Dual Output) | | **Output Current** | ±200mA | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 1kV DC (standard) / up to 3kV DC | | **Efficiency** | 80% - 84% (typical) | | **Package Type** | DIP14 / SMD (R suffix indicates Reel) | | **Operating Temp** | -40°C to +85°C | --- ### 2. Key Features & Symbols The suffixes in the part number "RTD-0505/P-R" provide specific information about its build: * **Dual Output:** It splits a 5V input into two separate 5V rails (positive and negative), which is ideal for powering operational amplifiers (Op-Amps). * **"/P" (Protection):** Indicates that the device includes short-circuit protection (Continuous Short Circuit Protection). * **"-R" (Tape & Reel):** Refers to the packaging method for automated assembly (SMD version). * **Galvanic Isolation:** It provides physical separation between the input and output circuits, preventing ground loops and protecting sensitive logic components from high-voltage spikes. --- ### 3. Pin Configuration (Internal Logic) The device is typically used in a 6-pin or 14-pin footprint. The internal electronic layout follows this logic: ```c Pin 1: -Vin (Ground) Pin 2: +Vin (Positive Input) Pin 3: NC (No Connection) Pin 4: Com (Common Ground for Output) Pin 5: -Vout (Negative 5V Output) Pin 6: +Vout (Positive 5V Output) ``` --- ### 4. Common Applications * **Operational Amplifiers:** Providing the +/- voltage rails required for analog signal processing. * **Industrial Controls:** Isolating logic-level controllers from noisy actuator environments. * **Data Acquisition:** Reducing noise interference in high-precision sensor readings.
