LED Drivers

LED drivers are power supply devices designed to regulate the flow of power to a Light Emitting Diode (LED) or group of LED’s. LED drivers provide a constant current source, meaning the LEDs are powered at a consistent current level, regardless of the voltage supplied to it. This ensures that the LEDs will stay shining at optimum brightness and over their entire lifetime.

One such device is the RACD20-700/277 application field and working principle. This device is designed for streetlight applications using pulse width modulation (PWM) to regulate the flow of current to the LED’s. The device can supply between 10W to 200W of current to the LED’s, depending on the needs of the application.

The device operates by reading a frequency signal set by the PWM which dictates the amount of light produced by the LED’s. In turn, the voltage supplied to the LED’s increases or decreases depending on the pulsing signal from the PWM. This creates a smooth transition between brightness levels, resulting in more efficient power consumption than traditional lighting.

The device is also equipped with a variety of safety features, such as overload, short circuit and current protection. This ensures that the LED’s are protected against accidental damage or misuse. Additionally, the device has current limiting functions variable from 50%-100%, allowing users to adjust the LED’s brightness as needed.

In conclusion, the RACD20-700/277 application field and working principle is a reliable and cost-effective device designed to regulate the flow of power to LED’s. It is ideal for streetlight applications, due to its ability to work with PWM and provide current limiting and safety features protect LED’s from damage.
