LXC35-2900SW Application Field and Working Principle

Introduction to LED Drivers

LED Drivers are devices that control the power delivered to LED loads in order to maximize efficiency and ensure consistent illumination over time. They are important in the field of light emitting diode (LED) lighting since LED fixtures require more precise control than traditional lighting types. A LED driver helps regulate power to the array of LEDs and protects the LED diode from receiving too much power.

LXC35-2900SW

The LXC35-2900SW is an LED Driver specifically designed for LED lamps. It is a constant current LED driver, meaning it provides a regulated output current in order to ensure optimal performance of LEDs. It has a wide input voltage range from 90VAC to 277VAC and can provide up to 3300mA of output current. Furthermore, the LXC35-2900SW is designed with overvoltage protection, over temperature protection, and open/short/over load protection.

Application Fields

The LXC35-2900SW is ideal for LED lighting applications such as linear indirect recessed lighting, surface lights, and suspended lights. These light fixtures often incorporate multiple sizes and types of LEDs where the LXC35-2900SW can prove invaluable. It can power LED lamps of various wattages from 0.5W to over 60W.

Working Principle

The LXC35-2900SW LED Driver works on the principle of output current regulation. It has an internal Pulse Width Modulation (PWM) controller, which regulates the output current to the LED load. It employs an active power factor correction technique, which allows for better harmonic performance and improved power factor without affecting the output current.When an LED load is connected to the driver, the output current is adjusted by a built-in voltage regulation function to compensate for voltage variances from the AC power supply or environmental conditions. The voltage feedback loop allows the LED driver to output a constant current with variances in line voltage, thus providing better performance over ambient temperature variations.The LXC35-2900SW LED Driver also incorporates a Soft Start mechanism to prevent the LED lamp from being damaged in case of sudden power surges. By gradually increasing the output current of the driver over time, it helps protect the LEDs from any inrush current that could damage them.

Conclusion

The LXC35-2900SW LED Driver provides various features that help make LED lamps operate more efficiently and last longer. Its wide input voltage range and output current control make it ideal for a variety of LED lighting applications. Its overvoltage, overtemperature, and short/open/overload protection help ensure the best performance from the LED load. The LED Driver utilizes a PWM regulation technique, a voltage feedback loop, and a soft start mechanism to maintain constant output current over time.
