TL50LW3U is a high efficiency, long life and broad control range led linear constant current driver. It can drive a wide variety of LED lighting products such as concentric, symmetrical, single/nagative single/double channels, desk lamps, wall washers,etc.Its automatic operation make it an ideal solution for light intensity control.This article will introduce its application field and working principle.

Application Field of TL50LW3U

The TL50LW3U is widely applied in various LED lighting products in household, commercial, industrial and entertainment lighting. Power supply for TL50LW3U range from 90 to 305VAC 50/60Hz and output power range from 30W to 60W. It is widely used for LED light source such as wall washers, landscape lighting, stage lighting, residential garden lighting, advertising lighting, etc.

Working Principle of TL50LW3U

The working principle of TL50LW3U is a feedback loop system, which can adjust the output current to the set value.According to the output current range of the TL50LW3U, the output current is divided into 10 fixed values.The output current is adjusted by the external feedback resistor.The current detection resistor is used to measure the output current of the LED constant current driver, and its voltage is compared with the reference voltage to obtain the current regulation range.The current detection resistor is connected to the negative output of the TL50LW3U, and the adjustment resistor is connected to the positive of the TL50LW3U.

How to Select the Adjustment Resistor of TL50LW3U?

The adjustment of the output current range of the TL50LW3U is implemented by adjustning the resistors in the feedback loop system. The adjustment resistor in the feedback loop system should be first selected according to its power dependence, and then the corresponding resistance value is selected according to the output current.Generally speaking, when the output current of the constant current driver converges to the set value, the voltage drop at the adjustment resistor should be 1V, or the LED indicator lights on.

Advantages of TL50LW3U

The TL50LW3U has the following advantages:

• High efficiency up to 90%, low power consumption than ordinary constant current driver
• Broad control range from 6V to 450V
• Minimize LED light source quickly and effectively
• Long life up to 50000 hours

Conclusion

In conclusion, TL50LW3U is a high efficiency, long life and broad control range led linear constant current driver, and it has been widely used in different LED lighting products.Its feedback loop system and adjustable output current range makes it an ideal solution for light intensity control. Its advantages including high efficiency, long life, and wide control range makes it attractive for LED lighting products.
