RBD-12-0.50/W

LED drivers are individual power supplies that provide power to single or multiple LEDs connected in series. LED drivers are an integral component of LED lighting providing controlled electrical power to the light source. If just the right amount of energy is not supplied to the light source, the LED cannot achieve its intended light output as well as longevity. The RBD-12-0.50/W is a rugged, water and dust resistent LED driver that offers adjustable current output, a wide input range, and assist operation in both indoor and outdoor environment.

Application Field of RBD-12-0.50/W LED Driver

This LED driver is widely used in line-powered LED lighting applications such as LED strips, spotlights, architectural lighting, decorative lighting, landscape lighting, and emergency lighting. They have been gaining popularity in the past few years as they can provide smaller form factor with low light dissipation and zero flicker operation. It has earned popularity in residential and commercial applications for its convenience.

Working Principle of RBD-12-0.50/W LED Driver

RBD-12-0.50/W LED driver converts line voltage to suitable power levels to power LEDs. This is done through a process called PWM (Pulse Width Modulation). This requires the switching of the power at an extremely high frequency and controlling the on-time and off-time of each period to achieve the desired current on the output. The higher the duty-cycle of the PWM signal, the higher will be the average current on the output.

The RBD-12-0.50/W LED driver is designed to provide constant current output, which is essential for optimal LED performance. To achieve this, it includes an integrated feedback circuit that constantly monitors the output current. This feedback is then compared with the set point and depending on the difference between the two, the microcontroller adjusts the pwm cycle to ensure that the desired average current is delivered to the output.

In addition, it is designed to operate in extreme environmental conditions and resist water and dust, and its internal components are assembled with conformal coating to protect against external moisture and dust. This makes them ideal for use in outdoor applications.

Conclusion

The RBD-12-0.50/W LED driver is a rugged and reliable driver that is capable of delivering optimal performance and efficiency in all types of applications. Its features make it suitable for a wide array of LED lighting applications. Its built-in feedback circuit ensures that the LED does not receive too much current, and its water and dust resistance make it suitable for outdoor applications.
