The **0C20-R** is a specific part number typically associated with **TDK-Lambda** (or formerly Nemic-Lambda) power supplies, specifically within the **RT Series** or **R-Series** of AC-DC converters. It generally refers to a modular or chassis-mount power supply unit. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The 0C20-R is a power component designed for industrial and medical applications where high reliability and stable DC output are required. | Feature | Description | | :--- | :--- | | **Manufacturer** | TDK-Lambda / Nemic-Lambda | | **Component Type** | AC-DC Power Supply | | **Mounting Type** | Chassis Mount / Internal | | **Input Voltage Range** | 85-265VAC (Universal Input) | | **Standard Output** | Typically 5V, 12V, or 15V (depending on sub-configuration) | | **Protection Features** | Overvoltage, Overcurrent, Thermal Protection | --- ### 2. Key Electronic Features * **Convection Cooling:** Designed to operate without the need for active fans in many configurations, reducing noise and mechanical failure points. * **Low Ripple and Noise:** Engineered for sensitive electronic circuits that require a clean DC signal. * **Isolation:** High dielectric strength between input and output, ensuring safety and preventing ground loops. * **EMI/EMC Compliance:** Built-in filters to meet international standards for electromagnetic interference. --- ### 3. Connection Pinout/Interface While the specific pinout can vary based on the frame size, the "R" series generally follows this standard layout: 1. **AC (L):** Line input. 2. **AC (N):** Neutral input. 3. **FG:** Frame Ground (Earth). 4. **-V:** Negative DC output terminal. 5. **+V:** Positive DC output terminal. 6. **V.ADJ:** A potentiometer used to fine-tune the output voltage (usually ±10%). --- ### 4. Common Applications * **Industrial Automation:** Powering PLCs, sensors, and control panels. * **Medical Equipment:** Due to its low leakage current and high isolation ratings. * **Telecommunications:** Used in base stations and networking hardware. * **Test and Measurement:** Powering laboratory instruments. --- ### 5. Part Number Suffix Meaning In the TDK-Lambda nomenclature: * **0C:** Often refers to the case style or power rating category. * **20:** Usually indicates the power wattage (e.g., 20 Watts). * **R:** Signifies the "Remote" sensing capability or a specific Revision/Series identifier (RT/RS). ---
