### 2. Key Electronic Components & Features
The internal circuitry of the 95DW-R3 consists of several critical stages to ensure stable power delivery:
* **Input Filter:** Typically includes a Pi-type ($\pi$) filter to minimize electromagnetic interference (EMI) and reflected ripple current.
* **PWM Controller:** A high-frequency pulse width modulation chip that manages the switching cycle to maintain a steady output voltage regardless of input fluctuations.
* **Isolation Barrier:** Uses a high-quality transformer to provide galvanic isolation between the input and output circuits, protecting sensitive downstream components.
* **Protection Circuits:**
* **Continuous Short Circuit Protection (SCP):** Automatically recovers once the fault is removed.
* **Over-Load Protection (OLP):** Prevents damage during current spikes.
* **Under-Voltage Lockout (UVLO):** Shuts down the unit if input voltage drops below a safe threshold.
