Core Functional Components To understand the electronic parts inside and surrounding this module, we categorize them as follows: #### A. Internal Circuitry * **Switching Controller:** Uses high-frequency Pulse Width Modulation (PWM) to convert the DC input into a high-frequency AC signal. * **Isolation Transformer:** A miniature ferrite-core transformer that provides the 1500VDC galvanic isolation between the 24V input and 15V outputs. * **Rectification & Filtering:** High-speed Schottky diodes and internal ceramic capacitors (MLCC) convert the AC back to stable ±15V DC. * **Linear Regulator (RZ Series Feature):** The "RZ" suffix denotes that the output is **regulated**. This means internal feedback circuitry ensures the output stays at exactly 15V even if the input voltage fluctuates or the load changes. #### B. External Recommended Components To ensure electromagnetic compatibility (EMC) and longevity, the following external parts are typically used in a circuit design: ```cpp // Typical Input Filter Setup 1. Input Capacitor (Cin): 4.7µF to 100µF (Electrolytic or Ceramic) - Purpose: To reduce input ripple and handle surge currents. 2. Output Capacitor (Cout): 10µF to 22µF (Low ESR) - Purpose: To further smooth the ±15V output for sensitive analog loads. 3. Protection: A Fuse or TVS Diode - Purpose: To protect the module from overvoltage spikes or reverse polarity. ``` --- ### 3. Applications and Usage This specific part is widely used in industrial and telecommunication sectors for: * **Operational Amplifiers (Op-Amps):** The dual ±15V output is the standard power requirement for high-precision analog signal processing. * **Sensor Interfaces:** Providing isolated power to sensors to prevent ground loops. * **Data Acquisition Systems:** Ensuring clean, isolated power for ADC/DAC components.
