LED Drivers

LED drivers provide power to LED lighting devices. A driver is a transformer that changes the input voltage to match and regulate the current to the LED. LED drivers are efficient and provide an extended life to LED lighting products. The LDD-500LS is a constant-voltage LED driver designed for LED lighting applications.

The LDD-500LS LED driver features a built-in active PFC circuit and low THD. This means it can achieve 100% PFC without employing a current-source V IN rectifier and can provide superior harmonic reduction. The active PFC circuit takes into account the smallest environmental fluctuations and quickly supplies the optimal power.

The LDD-500LS offers an output power up to 500W, with a wide range of voltage adjustment from 40Vac to 305Vac, and is compliant with worldwide safety regulations. It is also fully dimmable and has a MTBF of over 60000 hours. In short, the LDD-500LS is a reliable and high-performing LED Driver with a wide variety of applications.

Applications Field

The LDD-500LS LED driver is suitable for a variety of applications, such as industrial lighting, commercial lighting, and residential lighting. Its wide output power makes it suitable for high-power indoor or outdoor LED lighting. It can also be used in medical lighting, office lighting, stadium lighting, and other specialized LED lighting applications.

The LDD-500LS LED driver can be used for direct AC input using a hot-plug design. This allows for a power-reactive startup and hot-swap without the need for additional contactors or PFC controllers.

Working Principle

The LDD-500LS LED driver converts AC voltage from the power grid into DC voltage for LED Lighting applications. It is a constant-voltage LED driver that is specifically designed for carrying out active power factor control (PFC) of LED Luminaires. This LED driver uses a closed loop control, which can efficiently regulate the output parameters and keep the total harmonic distortion (THD) below 20%.

The LDD-500LS LED driver uses a peak current mode control (PCM) circuit to regulate the output voltage and current. This type of control circuit provides high current efficiency and high accuracy output voltage regulation. Moreover, it is capable of withstanding large load transient and has superior power factor correction.

The LDD-500LS is designed for high efficiency and long life. It has a high efficiency of up to 95%, a power factor of greater than 0.95, and a low THD rating of less than 20%. These features make the LDD-500LS an excellent choice for a variety of applications.

In summary, the LDD-500LS LED driver is a reliable and efficient LED driver with a wide variety of applications. It is capable of providing high accuracy output voltage with a high power factor and low THD. The LDD-500LS is capable of providing extended life for LED lighting products, making it an excellent choice for a wide range of LED lighting applications.
