The **RTS-2409-R** is a high-performance DC/DC converter manufactured by **RECOM Power**. It belongs to the RTS series, which is characterized by its compact size, high isolation, and unregulated output. Below is a detailed breakdown of its electronic specifications and characteristics. ### 1. General Specifications The RTS-2409-R is a SIP8 (Single In-line Package) surface-mount or through-hole component designed to convert a 24V DC input into a 9V DC output. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 24V DC (Nominal) | | **Output Voltage** | 9V DC | | **Output Current** | 222mA | | **Power Rating** | 2 Watts | | **Efficiency** | 80% - 85% (Typical) | | **Isolation Voltage** | 1kV DC / 1s (Standard) | | **Package Type** | SIP8 (Sub-miniature) | --- ### 2. Key Electronic Components & Internal Design While the internal schematic is proprietary, the "RTS" series generally employs the following architectural elements: * **Switching Controller:** Uses a high-frequency internal oscillator to convert DC to AC for transformer processing. * **Isolation Transformer:** Provides galvanic isolation between the input and output circuits, protecting sensitive downstream components from surges or ground loops. * **Rectification & Filtering:** High-grade ceramic capacitors are typically integrated to minimize output ripple and noise. * **Protection:** Includes short-circuit protection (usually limited duration) to prevent thermal runaway. --- ### 3. Pin Configuration (SIP8) The RTS-2409-R follows a standard pinout for industrial DC/DC converters: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | +Vin | Positive Input Voltage | | 2 | -Vin | Negative Input Voltage (Ground) | | 5 | -Vout | Negative Output Voltage | | 7 | +Vout | Positive Output Voltage | | 8 | NC | No Connection (Used for mechanical stability) | --- ### 4. Technical Performance Notes * **Unregulated Output:** This part is "unregulated." This means the output voltage will vary slightly depending on the load. If the load is very light, the voltage may rise above 9V; if the load is heavy, it may dip. * **Operating Temperature:** It is designed for industrial environments, typically rated from **-40°C to +85°C** without derating. * **EMI/EMC:** To meet Class B EMC standards, an external filter (C1, L1) is usually recommended on the input side. --- ### 5. Typical Applications * **Industrial Automation:** Providing isolated power for sensors. * **Data Communication:** Breaking ground loops in RS-485 or CAN bus systems. * **IGBT Gate Drivers:** Providing the necessary isolated bias voltage.
