LED Indication - Discrete refers to the use of Light Emitting Diodes (LEDs) for specific visual indications on various electrical or electronic systems. One key application area for this type of LED indicator is the QTLP680C7TR, an LED Panel Mount Indicator.

QTLP680C7TR Overview

The QTLP680C7TR LED Panel Mount Indicator is a LED-in series connecting type LED panel indicator. This indicator offers a current test range of 0.3W to 1.6W and a voltage test range from 12V to 18V. Additionally, the QTLP680C7TR boasts a viewing angle of 120 degrees, an operating temperature range between -20 to +85°C, and a switching capacity of 21A.

The QTLP680C7TR has several unique features that make it the ideal choice for many applications. These features include the choice of four different brightness levels and an optional illumination, an IP67-rated waterproof design, and a built-in gluing slot. Not only are these features ideal for long-term use and reliability, but they also enable the user to customize their QTLP680C7TR.

Application Field

Due to its high-temperature and waterproof design, the QTLP680C7TR is ideal for many industrial, commercial, and residential uses. These applications include but are not limited to automotive, laboratory, panel-mount, relay control, remote control, and other heavily-used electronic control applications. It is also a reliable and cost-effective solution for any applications that require an LED indicator to indicate various states such as on-off, open-closed, high-low, or any other visual display.

The wide range of illumination options, size, and connection types make the QTLP680C7TR suitable for all kinds of indicators, including those with either 12V or 18V power supply. In particular, its built-in mounting slots make it easy to mount the LED indicator to flat surfaces, eliminating the need to purchase additional mounting materials.

Working Principle

The working principle of the QTLP680C7TR can be broken down into three distinct components: power supply, LED array, and switching.

The power supply for the QTLP680C7TR is usually a DC source, which is either 12V or 18V. This DC current passes through the connector and is then fed into the LED array, where it is applied to a resistor. The resistor lowers the current flowing through the LEDs to the proper level, ensuring they remain bright and consistent.

The next component of the QTLP680C7TR is the LED array— this consists of a series of LEDs going in series with each other. This helps to spread the current evenly across the array, increasing their brightness and intensity.

Finally, the switching component of the QTLP680C7TR consists of two electrical contacts that disconnect and reconnect the LED array from the power supply depending on the state of the system. This allows the user to control the LED array and ensure that it is not over-driven and consequently damages.

Overall, the QTLP680C7TR LED Panel Mount Indicator is an ideal choice for various applications. It offers a robust, waterproof design as well as an array of illumination options and is a cost-effective solution for many purposes. The three components of its working principle are the power supply, LED array, and switching, all of which contribute to its superior performance.
