QL331HD is a type of discrete LED indicator, used to indicate the status of industrial controllers and utility monitor system. The indicator is a combination of two components: colored lens and high-power LEDs.

QL331HD is mainly used for industrial and utility monitoring systems, such as HVAC (heating, ventilation, and air conditioning) systems, medical gas monitoring devices, fuel cell monitoring systems, and solar energy systems. It is designed to provide clear and distinct visual feedback, allowing the user to easily monitor the performance and function of critical systems.

The lens and LEDs are integrated into a single housing, which offers robustness and durability against dust, dirt, and moisture. The QL331HD is offered in a number of colors, including red, blue, green, yellow, and white; each providing distinct lights to indicate when a system is working as expected or when there is an issue to be addressed. The lens and LEDs are integrated in a single housing which is compatible with many standard 3/4 inch SS mounting form factors which allows for easier and faster installation.

QL331HD is a highly reliable indicator and provides visual feedback for on/off switching applications. The lens is based on an opaque-colored thermoplastic material which is specially designed to shrink to fit over the LED die, providing ample protection for the LED package. The lenses are constructed from a highly durable material and are resistant to most chemicals and wear. Additionally, the LED provides long-lasting performance and superior contrast in order to effectively provide visual information of different colors.

The working principle of QL331HD is based on a continuous flow of current to the LEDs. The current passes through the LED and is converted into a beam of light, with the light traveling through the lens to create the desired color. The intensity of the light can be regulated by controlling the amount of power sent to the LEDs. The color of the light can be changed by simply replacing the lens. The color of the lens depends on the user’s choice. By changing the colored lens, the indicator will provide a different shade of light.

QL331HD is a reliable, durable and easily adaptable indicator. It is used in many industrial and utility applications and provides clear and distinci visual feedback. The combination of lens and LEDs makes it easy to monitor the performance and function of critical systems. It is also easy to install and maintain, with the color of the lens easily changed according to the user’s needs.
