The **PDA006A-700S-R** is a high-efficiency constant current LED driver manufactured by **Phihong**. It is designed specifically to power high-brightness LEDs in architectural, commercial, and residential lighting applications. --- ### ## Technical Specifications Below is a breakdown of the core electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 90V to 132V AC | | **Output Power** | 6 Watts (Maximum) | | **Output Current** | 700 mA (Constant) | | **Output Voltage Range** | 6V to 9V DC | | **Efficiency** | > 70% | | **Operating Temperature** | -20°C to +50°C | | **Power Factor** | > 0.9 | --- ### ## Key Electronic Features 1. **Constant Current Regulation:** Unlike standard power supplies that keep voltage stable, this unit ensures a steady **700mA current**. This is critical for LEDs to prevent thermal runaway and ensure consistent brightness and longevity. 2. **Built-in Protection Circuits:** The device includes several safety layers: * **Short Circuit Protection:** Automatically recovers once the fault is removed. * **Over-Voltage Protection:** Prevents the output from exceeding safe limits if the load is disconnected. * **Over-Temperature Protection:** Reduces output if the internal components get too hot. 3. **Power Factor Correction (PFC):** With a power factor of >0.9, it is highly efficient in its usage of AC power, reducing the "reactive power" returned to the grid, which is often a requirement for commercial building codes. 4. **Compact Form Factor:** The "A" series housing is typically designed to fit into small fixtures or junction boxes, often utilized in "downlight" or "track lighting" setups. --- ### ## Application & Wiring The unit features standard lead wires for input and output: * **AC Input:** Typically Black (Line) and White (Neutral). * **DC Output:** Red (Positive +) and Black (Negative -). > **Warning:** Always ensure the total forward voltage of your LED string falls between **6V and 9V**. If the voltage required by the LEDs is outside this window, the driver may flicker or fail to light.
