IDPC-45A-1050 Datasheet/PDFLEDs (light-emitting diodes) are one of the most popular and energy-saving lighting solutions available today. As LEDs are becoming more and more popular, the need for reliable, feature-packed LED drivers is also increasing. LED drivers ensure precise and consistent lighting performance by converting an unregulated voltage supply from either the AC mains or a DC source into a constant current to regulate the intensity of the LED. One of these LED drivers is the IDPC-45A-1050, and this article will discuss its application field and working principle.
Applications of the IDPC-45A-1050
The IDPC-45A-1050 is a constant-current, constant-voltage LED driver designed for use in LED lighting applications. It is versatile and can be used in a wide range of installations, from non-dimmable residential lighting to high-end commercial lighting applications. This LED driver is capable of driving maximum loads of up to 45 watts and can be used in single- or multi-stage systems. It provides a constant current output of 0-50mA and a maximum voltage output of 50V. It also has a wide input voltage range of 100-277V, which makes it suitable for use with both residential and commercial power supplies.
The Working Principle of the IDPC-45A-1050
The IDPC-45A-1050 relies on a switching method known as constant-current, constant-voltage (CC/CV) to regulate the current to the LED. This method functions using a basic feedback loop that allows the LED driver to sense and adjust the output current based on the current drawn by the LED. The LED driver uses two circuit elements that together form the CC/CV feedback loop. The first element is a sensing resistor, which is typically placed between the output of the LED driver and the LED load. This sensing resistor monitors the current flowing through it and reports this data back to the IC controller inside the LED driver. The second element is an IC controller that compares the output current of the LED driver to the load current sensed by the sensing resistor at all times. If the output current is higher than the load current, the controller will reduce the output current to maintain the desired output current that is pre-set. Conversely, if the load current is higher than the output current, the controller will increase the output current to bring it back up to the target current.
Conclusion
The IDPC-45A-1050 is a versatile LED driver that can be used in a variety of LED lighting applications. It is powered by a constant-current, constant-voltage switching method that ensures precise and consistent lighting performance. With its wide input voltage range and maximum load of 45 watts, it is suitable for use with residential and commercial power supplies.
