LED Drivers - LPF-90D-36 Application Field and Working Principle

LED drivers convert electricity from a universal power supply to the correct voltage, current and frequency range required for an LED. Drivers are designed to produce constant power regardless of the changing voltage from the universal power supply, making them ideal for LED headlights and lamps. The LPF-90D-36 LED driver offers the advantages of high efficiency, low ripple voltage and low temperature. It provides safe and reliable power output for many LED applications, including street lighting, home lighting, and decorative lighting.

Construction

The LPF-90D-36 LED driver has a low profile, metal-encased construction with high reliability and long life. It is designed for outdoor use and is resistant to dust, humid, and salt fog. The driver also has a thermal cut-off feature to help prevent overheating and product damage.

Input Power

The LPF-90D-36 LED driver operates at AC 90V to 265V input and has a universal input voltage feature (100 V ~ 240V). The input power is automatically adjusted to match the necessary output voltage according to the input voltage, making the driver suitable for international use.

Output Voltage

The LPF-90D-36 LED driver can be configured to deliver a wide range of output voltages, depending on the application. It can be adjusted from 12V-14V with a maximum current output of 36W. These adjustable output features allow the driver to be used as an LED dimmer or for other applications requiring a step-down voltage.

Protection Features

The LPF-90D-36 LED driver has several features that protect against overvoltage, undervoltage, short circuits, and over-temperature. It also includes a soft start feature to reduce both power surges and inrush currents. This helps extend the life of the LED driver and decreases the risk of product damage.

Working Principle

The LPF-90D-36 LED driver uses the active PFC (Power Factor Correction) technique to accurately convert AC power into a stabilised DC voltage supply. This technique ensures a reliable and consistent power output for LEDs. The driver uses an isolation transformer to create an alternating magnetic field from its primary winding section, which is then rectified and filtered into a stabilised DC output. This enables it to receive varying input voltages and produce a consistent voltage output to power LEDs. The driver is also equipped with a feedback loop to control its output voltage and current. This feedback loop ensures the LED driver produces the correct output for the specific LED connected to it, making it suitable for many types of lighting and applications.

Conclusion

The LPF-90D-36 LED driver is an ideal choice for many applications requiring reliable and consistent power output. Its adjustable output, protection features, and active PFC technique make it an efficient and safe option for powering LED headlights, lamps, and decorative lighting.
