LE2950WL39018 Application Field and Working Principle

Panel indicators, or pilot lights, are universal components of switchgear and broader electrical installations. The element chosen for this article is one of the many panel indicators available – the LE2950WL39018. Manufacturing of this indicator is done by Approx Legrand, and it is employed in various applications – hence an exploration of its operating principle and its suitability for such purposes is provided here.

Overview of Operating Principle

The LE2950WL39018 is a type of LED indicator that is powered by the common 12 VDC and 24 VDC power supplies used in switchgear, automation, and electrical control systems. Given its operating voltage, an in-depth consideration of the LED indicator’s working principle can be outlined here. Fundamentally, these LED indicators utilize a switch to power its light- emitting diode component, which generates light whenever it is correctly connected with the circuit. To create a strong, long-lasting signal, the respective switch inside the LE2950WL39018 employs silver alloy contacts. In this way, as the switch is moved from one position to another, and the diode is provided with the correct voltage, the indicator will shine with a bright and reliable glow. Given the device’s operating principles, however, a closer look at the application field of the LE2950WL39018 is needed.

Usage in Different Fields

The LE2950WL39018 is employed in multiple areas of electrical engineering due to its robust nature and versatility. Wi and that in mind, let us examine the various applications of the LED indicator, and what makes it suitable for such purposes.One of the greatest assets of the LED indicator is its ability to be used on both low- and high-voltage lines. As it mentioned previously,the LE2950WL39018 can work with conventional power supplies ranging from 12 VDC to 24 VDC, and thus it proves reliable in instances where other types of indicators may fail. The indicator is also suitable for use in distributed control systems due to its high signal-to-noise ratio and fast response time. This is particularly true when using it in a 3-phase system,given its developed contact jumpers for such systems. The indicator also boasts durability; its LED is rated at up to 30000 hours of continuous usage, and its contacts are equipped with a 100,000-cycle life expectancy. This makes the LE2950WL39018 an effective choice for industrial installations where reliability may not be otherwise assured.Moreover, the indicator is designed with LED optimization in mind. Its light-emitting diode is fitted with a built-in lens, which helps to focus its radiation pattern and increase its luminous intensity. This contributes to an efficient operation and greater uniformity.

Conclusion

Panel indicators such as the LE2950WL39018 are components that are frequently found in modern switchgear, automation, and control systems. Their application is due to their robust nature and versatility, since they are able to work on both low- and high-voltage lines. Their LEDs are kept powered via a switch, with silver alloy contacts, and are made with long-lasting properties, for reliable operation. This article has shown a comprehensive overview of this LED indicator, its operating principle and its application field, demonstrating the LE2950WL39018 to be an excellent choice for industrial installations of all kinds.
