LED Indication – Discrete can be found in many different applications, from industrial and commercial to residential. Networks, communications systems, instrumentation, control systems, appliances, and machinery are all typical applications for LED Indication – Discrete. In this article, we will examine the 3AC5V-F application field and working principle.

What is a 3AC5V-F?

The 3AC5V-F is a three-wire system with a red, green and yellow LEDs in a single package. It has a 6mm XH2.54mm Pitch and a wide viewing angle of 160°, with a low operating current of typically 10mA max at 20mA. It is also available in non-dimmable or PWM dimmable (1-10V) versions, making it very versatile. It is used to indicate the status of a variety of applications, and is UL approved.

3AC5V-F Application Fields

The 3AC5V-F is used in a variety of different applications, from automotive to industrial and residential. In the automotive industry, it is used to indicate the status of vehicle functions, such as door locks and fuel levels. In an industrial environment, the 3AC5V-F may used to indicate safety and warning messages, such as machine enabled/disabled and operation status. In the residential environment, the 3AC5V-F is often used to indicate the status of home automation devices, such as security systems and lighting.

Working Principle of 3AC5V-F

The working principle of the 3AC5V-F is based on the basic principles of electricity and how LEDs (Light Emitting Diodes) produce light when current is passed through them. LEDs are two-terminal semiconductor devices that convert electrical current into light. The three-wire version of the 3AC5V-F has three distinct voltage settings. The red LED requires 3.4V, the green LED requires 3.9V and the yellow LED requires 5V. When an AC voltage is applied to the circuit, the LEDs will light up depending on the voltage applied. It is important to remember that LEDs are polarised devices and the polarity of the current must be taken into account.

Conclusion

The 3AC5V-F is a versatile and popular LED indication system used in many different applications. It has three distinct colours and is available in non-dimmable and dimmable versions. The 3AC5V-F works on the principle of electricity and the three distinct voltage settings will light up the appropriate LED depending on the AC voltage applied.
