Introduction

The NPF-90D-15 is a high efficiency LED driver that enables LED luminaires to be designed with multiple channels with different lead voltages and feed ranges. The driver has a wide operating range of input voltage, making it suitable for a variety of lighting applications. It is also capable of dimming the LED to different levels and providing protection from transient events.

Application Field

The NPF-90D-15 is suitable for use in both indoor and outdoor applications. It is ideal for any situation where lighting needs to be dimmable, such as in restaurants or retail spaces. The driver is also suitable for street and parking lot lighting applications where high output and energy efficiency are desired.

The driver is suitable for use in most commercial and residential LED applications, as it is designed to work with constant current LED chips. It is also compatible with many low voltage operation systems, making it ideal for use in solar systems.

Working Principle

The NPF-90D-15 LED driver utilizes pulse width modulation (PWM) technology. This technique works by rapidly changing the level of current passing through the LED chip. When the current passing through the chip is rapidly increased and decreased, the LED light level will vary between high and low levels. This allows the driver to control the brightness of the LED, enabling the end user to select the preferred level of illumination.

The NPF-90D-15 LED driver is capable of dimming the LED down to 1% of full brightness with no flickering. It also has thermal protection to ensure that the LED chip operates without risk of thermal over-temperature damage. The driver is also equipped with transient response circuitry to protect against high voltage surges.

Conclusion

The NPF-90D-15 LED driver is a high efficiency and robust solution to controlling LED lighting in a variety of applications. It is designed to be compatible with constant current LED chips and low voltage operations, making it a suitable solution for a wide range of lighting applications. The driver uses pulse width modulation technology to provide dimming capabilities, as well as thermal and overvoltage protection.
