It is widely used in outdoor applications such as LED outdoor lighting, street lighting, conduit lighting, and LED billboard lighting. It is also used in indoor applications such as LED indoor lighting, illumination lighting, down lighting, and LED panel lighting.

In addition to its universal applications, the LNE-48V120WDAA also has high-power application fields. It provides excellent performance in high-power LED lighting applications and is often used in industrial and commercial lighting. Examples of such lighting applications include LED high bay lighting, tunnelling lighting, stage lighting, and area lighting.

Working principle

The LNE-48V120WDAA is equipped with a high-power switching power supply that makes it capable of providing stable power for long periods of time. The power supply is typically designed with a high-frequency transformer and a high-frequency switching mosfet that can convert AC input to DC output. The output power is regulated by the steady current source, which is composed of a sensing diode and a resistor.

In order to maintain the output voltage level, the power supply includes a power factor correction (PFC) controller. The PFC controller increases efficiency and reduces power consumption during the start-up and operating stages. In addition, the LNE-48V120WDAA also includes various protection features, including over current, over voltage, overload, and temperature protection.

During operation, the PFC controller is used to enable the power supply to automatically adjust the LED current in order to reach the desired intensity. This is achieved by monitoring the output voltage and current and adjusting them accordingly. This ensures that the output power is consistent and reliable, while also maintaining the safe operation of the LED driver.

Conclusion

The LNE-48V120WDAA is an excellent LED driver for a wide range of applications. It is reliable, efficient, and capable of providing stable power even in high-power LED lighting environments. Its universal application fields make it a perfect choice for many types of LED-based lighting applications. Finally, its built-in PFC controller ensures that the output power is adjustable in order to achieve the desired intensity.
