LED Drivers, also known as LED Power Supplies, are essentially the backbone of any good LED lighting system. They are like the brain behind the system, controlling the flow of power and information to your LEDs. LED Drivers are necessary for regulating the power of the LED, especially in applications where dimming or temperature control is required. So, what are the application fields and working principles of PLED200W-040-C4900-D?

Application fields

The PLED200W-040-C4900-D LED Driver is a high-efficiency, high-reliability DC power supply optimized for driving long linear runs of LEDs. This driver can power multiple strings of up to 200 W of LEDs, making it ideal for commercial and industrial applications whixleh require a large amount of light. It is also equipped with a 0…40V variable output voltage that is adjustable through the integrated DALI or wired input interface, giving users the flexibility to control the brightness and color of their lights. The PLED200W-040-C4900-D is also well suited for lighting applications in outdoor environments, due to its high-voltage surge and lightning protection capabilities.

The PLED200W-040-C4900-D is also a great choice for medical applications, as it has the ability to reduce visible flicker, providing even lighting without any visible flickering or strobing. In addition, it features intuitive control functions, including adjustable current limiting, dimming control modes, power-good signal, and over-temperature protection, making it an excellent choice for operating in conditions of varying temperatures or environments.

Working Principle

The PLED200W-040-C4900-D operates on a Buck DC/DC LED driver topology. This means that it converts a relatively high input voltage from the power source into a lower, stable output voltage for driving Power LEDs. The current control is done by Pulse Width Modulation (PWM) pin, which sends a signal to a controller that adjusts the power of the LEDs. The controller then adjusts the LED output current and light level according to the chosen dimming or control method.

The PLED200W-040-C4900-D also has control functions, such as a power-good signal that indicates the LED driver is fully functional, and an over-temperature protection feature that shuts down the power supply when the temperature exceeds a specified level. This feature helps protect both the driver and the LED installations from damage due to excessive heat.

In addition, the PLED200W-040-C4900-D has a low standby power consumption, which means it does not consume a lot of energy when the LEDs are not in use. This makes it an ideal choice for green energy applications where energy efficiency is a priority.

Conclusion

The PLED200W-040-C4900-D is a high-efficiency, high-reliability LED Driver that is suitable for a variety of applications from commercial and industrial LED lighting to outdoor and medical applications. It is capable of controlling multiple strings of LEDs up to 200W in power and offers intuitive control functions such as adjustable current limiting, dimming control modes, power-good signal, and over-temperature protection. In addition, its low standby power consumption makes it an excellent choice for green energy applications.
