LDP040-240-00 Application Field and Working Principle

The LDP040-240-00 is a light-emitting diode (LED) driver that operates from a nominal 24V DC power supply. The driver is designed for LED lighting applications such as street lighting, area lighting and vehicle signals. The driver features auto-compensation and protection, with a wide dimming range of 0.2% to 95%. It provides good dimming linearity and is capable of delivering up to 4A of current.

The driver works by using pulse width modulation (PWM) to adjust the output current. When the LED driver receives a DC input voltage, the internal charging circuits convert this into a pulse-width-modulated (PWM) current. The PWM current is then delivered to the LEDs, which are connected in series with the driver, and the on-board LED protection circuits monitor the current and provide over-temperature and over-voltage protection when required.

The LED driver is highly efficient and has a power factor exceeding 0.95. Its low standby power consumption and flicker-free operation makes it suitable for energy-saving installations. The driver is also capable of IP67 protection, ensuring protection of the LED lighting system from dust and moisture.

The LED driver offers an optimal dimming range of 0.2%-95%, with dimming linearity of 85%. This ensures smooth and reliable dimming performance. The driver also offers excellent temperature stability, ensuring that the lights will not get too hot when used in extreme environments. It also has built-in electrical noise reduction filters for a more stable dimming performance.

The LDP040-240-00 LED driver is suitable for use in a variety of lighting applications, including street lighting, area lighting, signage, feature lighting, and vehicle signals. Its wide dimming range, high efficiency and temperature stability make it an ideal solution for energy-saving, low-maintenance installations.
