NPF-90-12

LED Drivers

LEDs are some of the most common light sources used in electronics, electricity, and lighting applications. The NPF-90-12 is one example of a driver specifically designed for LED applications. It is used for DC input and wide range applications, with an output current range from 20mA to 1200mA.

Application Field

The principal application field of NPF-90-12 is to serve as a DC power source for LEDs. The NPF-90-12 can be used for various purposes, such as direct connection to the LEDs or for driving an LED lamp/power supply. The device is typically used in LED backlight applications, where the light needs to be adjustable for various purposes.

In other applications, the NPF-90-12 can be used to provide constant current to the LED strip. Unlike conventional AC power supplies, these setups use DC current, which allows for more control and customization. One of the major advantages is that you can set the current to a predetermined level, which will ensure that the LEDs are supplied with the same current, no matter the ambient temperature. Additionally, the device ensures that the supply current does not fluctuate when the LED is turned on and off.

Working Principle

The NPF-90-12 works by providing a constant output current to the LED. It also has a wide input voltage range which makes it suitable for a variety of applications. The device functions as a boost controller, as it increases voltage as needed to maintain a constant current to the LED. The device also has the ability to adjust its output level depending on the number of LEDs connected at any given time.

The device also features an adjustable current limit feature which allows the user to set the current limit depending on the need. The current limit feature helps regulate the current level to prevent any potential damage or overheating of the LEDs.

The NPF-90-12 is designed to provide the highest possible efficiency and reliability when running LED applications. The device is designed to be as efficient as possible while still maintaining a reliable level of output. It is designed to ensure that the LEDs are supplied with current that is stable and consistent.
