LED Drivers

LED drivers are devices that efficiently manage the power delivered to LEDs. LED drivers can also be used to control LED brightness, allowing the user to adjust the output of the LED to suit the application. LED drivers come with a variety of features, some of which include dimming, current regulation, remote monitoring, and protection from power surges and other electrical irregularities.

LED25W-24 Application Field and Working Principle

LED25W-24 is a LED driver with 24V input and 25W output power from Mean Well. It is used to provide power to LED lighting and is especially suitable for LED emergency, traffic, automotive, rail, ship, agricultural and indoor systems. Its features include 1-10V dimming, 100-277VAC universal input voltage, PFC rate> 0.9, over temperature, open circuit and short circuit shut off protections and SFH data feedback. The LED25W-24 driver is also UL、CCC certified.

The working principle of LED25W-24 is based on constant current and voltage controls. The input voltage passes through a rectifier circuit and is converted into direct current, which is then filtered and regulated using a switch-mode regulator. The voltage regulator sets an optimal voltage level to provide a constant current for the LED load. The output current of the driver can be decreased or increased by controlling the duty ratio of the switch-mode regulator. This helps to maintain a constant current to the LED load. The LED25W-24 allows users to adjust the brightness of the LED lights by setting the voltage level and duty cycle of the switch-mode regulator using 1-10V dimming control.

Power factor correction (PFC) is an important feature of the LED25W-24 which ensures peak efficiency of the driver and also protects the power grid by reducing harmonics. The LED25W-24 has a power factor up to 0.9, which makes it suitable for many applications. The over temperature, open circuit and short circuit shut off protection helps to optimize the working temperature of the driver and protect the internal components of the driver from damage due to overcurrent.

Conclusion

The LED25W-24 is an efficient LED driver suitable for many applications. Its features include 1-10V dimming, 100-277VAC universal input voltage, PFC rate> 0.9, and over temperature, open circuit and short circuit shut off protections. The driver works by regulating the voltage and current of the LED load using a switch-mode regulator. The LED25W-24 can be used to effectively increase the efficiency of the LED lighting and to protect the power grid by reducing harmonics.
