The **RSS-3.324/P-R** is a high-performance, isolated DC/DC converter manufactured by RECOM Power. It belongs to the RSS series, which is designed for applications requiring high power density and reliable isolation in a compact SMD (Surface Mount Device) package. --- ### 1. Technical Specifications The following table outlines the primary electrical characteristics of the RSS-3.324/P-R: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Input Voltage** | 3.3V DC | Nominal input range (typically ±10%) | | **Output Voltage** | 24V DC | Fixed secondary output | | **Output Power** | 1 Watt | Maximum power rating | | **Efficiency** | 70% - 80% | Varies based on load | | **Isolation Voltage** | 1kV DC | Standard isolation (P-suffix indicates high isolation) | | **Package Type** | SMD | Surface Mount Device (14-pin) | | **Operating Temp** | -40°C to +85°C | Full load range without derating | --- ### 2. Part Number Breakdown The nomenclature of the part number reveals its specific configuration: * **RSS**: Series name (1W Single Output, SMD). * **3.3**: Nominal Input Voltage (3.3V). * **24**: Nominal Output Voltage (24V). * **P**: Short-circuit protection (Continuous). * **R**: Packaging type (Tape & Reel). --- ### 3. Key Electronic Features #### A. Galvanic Isolation This component provides **1kV DC isolation** between the input and output stages. This is critical for: * Breaking ground loops. * Protecting sensitive low-voltage logic (3.3V) from higher voltage noise or surges on the 24V rail. #### B. Short Circuit Protection (SCP) The **/P** designation indicates that this model includes **continuous short-circuit protection**. Unlike basic converters that might overheat and fail during a fault, this unit will automatically recover once the short circuit is removed. #### C. Power Density Because it is an SMD component without an internal pot core, it occupies a very small footprint on the PCB, making it ideal for space-constrained industrial electronics. --- ### 4. Typical Applications * **Industrial Automation:** Powering 24V sensors or actuators from a 3.3V logic board. * **Data Acquisition:** Providing isolated power to analog-to-digital converters (ADCs). * **Communication:** Isolating RS-485 or CAN bus interfaces. ---
