LED Indication - Discrete is an important subset of Indication solutions for signalization and product identification. As an electrical device, the VLMY31J1K2-GS18 is designed for LED Indication - Discrete applications, allowing engineers to design with less complexity, higher accuracy, improved reliability and faster installation times.

Typically, LED Indication - Discrete need to combine field-level isolation, overload protection, current limiting and thermal shutdown functions, making it difficult for engineer’s to come up with a reliable solution. VLMY31J1K2-GS18 offers an integrated solution which not only functions very well, but also simplifies the design. It offers a wide input range of 6.5 to 36 volts, which is sufficient to cover almost all applications, while providing a tight control over the output voltage and current.

VLMY31J1K2-GS18 provides a combination of two operation modes, an Forward and a Flyback mode, which allow it to be used in various switching applications. The Forward mode is suitable for "hard" switching applications, where the output current needs to remain constant at all times, while the Flyback mode is designed for "soft" switching applications, which need a controlled return current. The combination of these two modes allow the device to operate over a wide range of input and output temperatures.

VLMY31J1K2-GS18 includes over current, over temperature, and under voltage protection circuitry, which protects the LED against over-currents and excessive temperatures and provides a fail-safe protection in case of voltage spikes or overloads. This allows the LED to operate reliably at temperatures ranging from -40°C to +125°C and provides high reliability even under extreme temperature conditions.

In addition to over temperature, over current, and under voltage protection, VLMY31J1K2-GS18 also integrates a high EMI filter, which eliminates interference with other connected devices, reducing the overall risk of data loss and malfunctions. The fault mode built into the device keeps the output current low when a fault occurs and prevents potential damage to more sensitive components.

Finally, VLMY31J1K2-GS18 also provides a built-in soft-start and fade-in feature, which ensures a smooth and controlled transition of light outputs when powering up and down the LED. This minimizes the risk of accidental light "flashes" and helps to extend the life span of the LED.

In conclusion, the VLMY31J1K2-GS18 is an ideal solution for LED Indication - Discrete applications due to its combination of features that provide protection and improved performance, making it a reliable and long-lasting solution for any application.
