LED Drivers

LED drivers are electronic devices that convert input power to the appropriate levels and currents required to safely and efficiently drive light emitting diodes (LEDs).

IDLV-25-24 Application Field and Working Principle

The IDLV-25-24 is a constant voltage LED driver for powering 24V single-color LEDs. The device is suitable for indoor applications, including residential, commercial, and industrial as well as outdoor applications like signage and façade lighting. It takes an input voltage of 100 - 277Vac, and is capable of driving a maximum load of 25W. The features of the device include adjustable output current limiting, short circuit protection, over-temperature protection, over-voltage protection, and overload protection.

The working principle of the LED driver is based on the buck-boost topology. It is based on a two-stage converter where the input voltage is alternatively stepping down to generate a lower output voltage and stepping up to generate a higher output voltage depending on the input voltage. A control loop is included to regulate the output voltage and protect the LED from over-voltage and current. The constant DC voltage output keeps the LED lamps at a constant brightness. This is a highly efficient driver circuit, ensuring maximum power saving and long life.

The LED driver features a range of protection functions for safe operation of the device and LED lamps. These include an open/short circuit protection that prevents an electric surge, a thermal protection that shuts down the output in case of overheat, a thermal shut down that stops the output current to prevent malfunction of the drive, and a power-on reset protection that ensures reliable restarting of the output current.

The LED driver is an ideal solution for powering 24V single-color LEDs, allowing customers to customize and optimize the output current to match the needs of differing applications. The wide range of features and protections makes it a very reliable and safe LED driver for indoor and outdoor applications.
