The LN21RCPH is an LED indicator module which is categorized under the LED Indication – Discretepart of the technology. It is a high intensity, waterproof, and multi-mode indicator. It is most commonly used in applications such as alarm systems, warning systems, asset tracking devices, and other similar functions that require an LED indicator to be visible.The LN21RCPH has a few outstanding features that make it stand out against other LED indicators, such as its miniature and lightweight size, its waterproof and highly efficient power-saving of up to 95%, its color-coded installation capability, and multi-mode (Flash, Steady, and Pulse) operation.The LN21RCPH is designed to be used with a transformer, generator, or other suitable power source, which when connected to the module will power the LED. When some form of external stimulus is applied to the module, it will then activate the LED for a specified duration.The main components of the LN21RCPH include the LED, an opto coupler, a wide voltage inverter circuit, and a resistor.The LED has a wide range of emission colors, ranging from white to red, blue, green, yellow, and more. The LED is also available in different sizes and configurations. Its design allows for simple installation and a low profile, as well as making it highly visible during daytime and night-time lighting as well as operating in any weather conditions.The opto coupler is used to isolate the power supply voltage from ground and make sure that the current flow is kept safe. This prevents any power overloads or reverse polarity currents which could damage the module.The wide voltage inverter circuit is used to regulate and supply the correct voltage to the LED. This circuit is designed to ensure that the module is able to be used with a variety of different power sources, such as 12V or 24V DC.The resistor is used to set the module’s current-limit for the LED. This helps ensure that the LED operates within safe parameters and prevents it from burning out.When the LN21RCPH receives an external stimulus, the LED will be activated and its power supply will be converted to the appropriate level before being supplied to the LED. Depending on the mode, the LED will then flash, pulse, or remain steady for a specified duration before being deactivated.The LN21RCPH can be used in a variety of applications, including but not limited to marine and industrial applications, emergency response vehicles, and monitoring systems. It is an extremely reliable and effective form of indication for when the user needs the LED to be visible in any lighting condition or environment.
