LED Drivers are used to provide power for light emitting diodes and are available in a variety of forms, such as PLED120W-266-C0450-D. The use of this driver in specific applications and the working principle are explored in this article.

Applications

PLED120W-266-C0450-D is widely used in outdoor LED Lighting applications for illumination, such as security lighting, landscaping lighting, billboard lighting, tunnel lighting, and other commercial and industrial applications. It is also suitable for indoor lighting, such as residential lighting, residential decoration lighting, office lighting, and other kinds of lighting.

Apart from lighting, the driver is also used in other applications such as LED displays, LED lighting systems, LED backlighting, LED screens, and other light box LED lighting.

Working Principle

This LED driver uses an advanced technology known as Constant State Current (CSC) to ensure that the LED output current can be regulated to the designed level with minimum deviation. It uses a closed-loop control to adjust the pulse width modulation (PWM) applied to the LED and keeps the output current at the desired level even under different operating conditions.

The power stage of the driver is composed of an isolated DC/DC converter that uses high frequency switching transistors to convert the input voltage into a regulated output. The output is further regulated using an adjustable current control and an isolating voltage regulator.

The LED driver is designed with smart features that will protect the LEDs in the case of short circuits, over voltage, over current, and other types of potential damages. It also has high efficiency and is capable of operating in wide input voltage range.

Conclusion

PLED120W-266-C0450-D is a LED driver that is used in various lighting, display, and backlighting applications. It uses an advanced Constant State Current technology to regulate the output current to the designed level, and features smart protection capabilities to protect the LEDs from potential damages. It is also highly efficient and flexible in terms of input voltage range.
