Introduction about LED Drivers

Light emitting diode (LED) drivers are commonly used in LED lighting systems, providing the power between an LED and the input power source typically required by electronic circuits. LEDs are simple in focus but complex in the necessary power supplies. The power management semiconductor industry is meeting these requirements by designing a range of LED drivers for high efficiency, flexible control, dimming, and cost-efficient applications.

RACT20-1050 Application Field and Working Principle

The RACT20-1050 is a Class 2, Constant Voltage LED driver range designed to provide a simple, low cost, high efficiency, constant voltage LED driver. This product is well suited for a variety of automated LED lighting installations. It is able to power up to 10A LED light with a voltage range of 18V to 58V, while operating with an input voltage from 115V to 340V. By using constant current, constant voltage control, accurate LED voltage and current stability can be easily achieved. This LED Driver can be used to light either commercial or residential applications, such as LED downlights, LED bulbs and LED light strips.Its working principle is simple. The AC input voltage is first rectified and then filtered to form a DC voltage. After that, a constant voltage power factor regulation drive circuit is used to convert the DC voltage into an equivalent AC output. The AC output from the circuit then passes through a transformer to reduce the voltage to form a steady DC power supply to the LED power source. The LED driver has protection circuits built in to protect the LED from over-voltaging or over-loading.

Conclusion

LED drivers are an important part of any LED lighting system. The RACT20-1050 is a Class 2, Constant Voltage LED driver specifically designed for efficient, cost effective LED lighting applications. Its working principle is simple, using constant current, constant voltage control to provide an accurate, steady LED voltage and current stability, along with built in protection circuits for added safety. This LED driver is versatile and can be used for a variety of LED lighting installations, from residential to commercial applications.
