The **PDA006A-350S-R** is a high-efficiency LED Driver manufactured by **Phihong**. It is specifically designed for indoor architectural and residential lighting applications, providing a constant current output to power LED strings. --- ## 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Output Type** | Constant Current (CC) | | **Output Current** | 350 mA | | **Output Power** | 6.3 Watts (Max) | | **Input Voltage Range** | 100 ~ 240 VAC | | **Output Voltage Range** | 12 ~ 18 VDC | | **Efficiency** | ~75% at 120VAC | | **Isolation** | Class 2 Rated | | **Protection** | Short Circuit, Over-Voltage, Over-Temperature | --- ## 2. Core Features & Operation The internal circuitry of the PDA006A-350S-R is built to ensure stability and longevity for LED components: * **AC/DC Rectification:** It converts standard AC wall power into the DC voltage required by LEDs. * **Constant Current Regulation:** Unlike standard power supplies, this driver maintains a steady **350mA** current flow. This is critical because LEDs are current-driven devices; fluctuations in current can lead to overheating (thermal runaway) or premature failure. * **Safety Protections:** * **Short Circuit Protection:** Automatically recovers once the fault is removed. * **Over-Voltage Protection:** Prevents damage if the output voltage exceeds the 18V threshold. * **Compact Form Factor:** The "A" series housing is designed to fit into small junction boxes or narrow light fixtures. --- ## 3. Wiring Configuration The device typically features four wire leads for integration: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Black** | AC Line (L) | Input: Connects to the Hot wire of the AC source. | | **White** | AC Neutral (N) | Input: Connects to the Neutral wire of the AC source. | | **Red** | LED+ | Output: Connects to the Anode (+) of the first LED. | | **Blue/Black** | LED- | Output: Connects to the Cathode (-) of the last LED. | --- ## 4. Typical Applications * **Recessed Downlights:** Ideal for small 6W LED puck lights. * **Accent Lighting:** Used in displays or under-cabinet lighting. * **Commercial Signage:** Powering small LED modules for backlit letters.
