HLMPK401 LED Indication - Discrete Application Field and Working Principle

The HLMPK401 LED Discrete Indication is a part of the Universal Discrete Indicators Series from LiteOn, a manufacturer of high-quality LED devices. Featuring a long, thin body shape, the HLMPK401 is primarily used when space is limited. This design also aids in portability, and many HLMPK401s can be easily stored in any small area.The HLMPK401 is designed to display a single LED indication in a number of LED colour combinations and intensity levels. This makes it ideal for applications ranging from simple warning signals, to more complicated schematic designs. The HLMPK401 can also be configured to support a dimming control input (DCI), enabling users to control the brightness of the LED via an external signal.The HLMPK401 is powered by a constant current source, providing a constant current of up to 20mA. This ensures that the LED is illuminated brightly and with consistent brightness over current. The starting voltage of the HLMPK401 is typically 4.1V, but this can be adjusted by a range of voltage or current sources.In addition to its current source and wide range of LEDs, the HLMPK401 also includes an array of protection features. These include discharge protection, to prevent the device from becoming overloaded if excess voltage or current sources enter the system, and reverse polarity protection, to safeguard against short-circuiting if a battery or other energy source is connected to the system. This ensures that the HLMPK401 functions safely in any application.The HLMPK401 is a versatile indicator, providing users with an easy-to-install package that can be adapted to a wide range of requirements. The combination of its flexibility, protection features, and easy configuration make it a popular choice for many applications. The HLMPK401 is a reliable and cost-effective solution for any application involving LED indication, and its use in a variety of industries is a testament to its versatility.
