The EAST3215YA3-AM is a discrete LED indication device that is used to indicate power/signal status. It\'s designed as a two-channel device: one for indicating power on/off status and the other for indicating signal actually transmitting/receiving. It\'s applicable for relatively low voltage application, such as 12V and 24V DC, up to a maximum of 36V DC.

The EAST3215YA3-AM operates with a rated switching power supply rating, the input voltage can be 85 – 270V AC or 100 – 360V DC, for example, a 12V power supply, which when accompanied with the application of a high power LED, will provide a steady and reliable source of long time illumination service.

The main working principle of EAST3215YA3-AM is based on a constant-current driver. When receiving a signal, the LED turns on, illuminating the LED with steady and constant current light. If a 12V power supply is applied, the input voltage is around 400mV to 2V, which will drive the LED to emit a dim light. This dim light can be made brighter by increasing the incoming voltage. The higher the voltage, the brighter the LED light.

Another important feature about the EAST3215YA3-AM is its wide selection of dimming options. It supports both pulse-width modulation (PWM) and digital control dimming. This allows users to select different brightness levels for different applications. The LED will dim according to the duty cycle of the PWM signal, or else dim according to the digital control dimming for the desired luminosity. This feature is especially valuable for applications that require adjustable illumination.

In addition, the EAST3215YA3-AM also has a power shutdown feature. If the input voltage falls below a certain level, or if there is no input voltage at all, the LED will automatically turn off, preserving power and saving energy. This feature is beneficial in many situations where the LED doesn\'t need to be on all the time, such as in the case of a switch or indicator.

The EAST3215YA3-AM is an ideal device for applications that require steady current, reliable illumination, and adjustable dimming. Its simple operation and wide selection of voltage input make it a great choice for many applications. And because of its low power consumption and long-term use, it\'s suitable for both personal and commercial uses.
