Introduction

LED indication is a popular way to visually indicate the state of a system. LED indications can be used to indicate a variety of statuses, from power on/off and fault detection to more complex statuses such as alarm status and system readiness. Discrete LED indicators are composed of single LED packages that are mounted onto a circuit board with the appropriate circuitry. The WP63SRC is one such discrete LED indicator designed with a special feature in mind – reliable power cycling.

Working Principle of WP63SRC

The WP63SRC discrete LED indicator is intended to be used in systems where power cycling is required for reliable operation and is specifically designed to prevent incidents of thermal runaway and runaway luminescence. The WP63CRC is a compact, discrete LED indicator that combines a high-power LED along with a current-limiting circuit and an integrated thermal protection circuit.The current-limiting circuit within the WP63SRC is responsible for limiting the forward current to the LED, even when subjected to wide voltage variations. This design ensures reliable performance and longterm stability of the circuit and prevents it from overloading or becoming damaged. The WP63SRC also contains an integrated thermal protection circuit that operates using the NTC (Negative Temperature Coefficient) thermal protection approach. The NTC approach makes use of a temperature sensing material to detect the current temperature in the environment and adjust the current-limiting circuit to match the temperature and prevent thermal runaway. The thermal protection circuit of the WP63SRC also offers an adjustable current setting through its SRC pin. This allows for fine-tuning of the protection level according to the specific requirements and conditions of the environment in which the LED indicator will be used.

Application Field of WP63SRC

The WP63SRC LED indicator is designed for reliable power cycling and is ideal for use in a variety of environments and applications. It is a great solution for providing reliable LED indication in alarm and warning systems, lighting systems, and industrial control systems. The WP63SRC is also suitable for use in automotive and marine applications as it is vibration-proof and waterproof. It can also be used in off-grid or remote applications that require reliable LED indication in low voltage and low current conditions. In these applications, the WP63SRC\'s thermal protection feature ensures that the LED indicator is never subjected to an excessive current and therefore never overheats.

Conclusion

The WP63SRC discrete LED indicator is designed to provide reliable LED indication in a variety of conditions and applications. With its integrated current-limiting and thermal protection circuits, it is able to provide reliable and safe operation even in environments with high power cycling requirements. Its SRC feature allows for increased flexibility and fine-tuning to ensure reliable operation even in demanding environments and applications. The WP63SRC is thereby a solid choice for any application where reliable and safe LED indication is required.
