LED Drivers, such as ELG-200-C2100D2, are used to provide a constant current to power an LED or group of LEDs. The driver module regulates the current, thus protecting the LED from the resistor or the DC battery voltage, which could easily be too high or too low depending on the output current. They also extend the lifetime of the LED, giving the light fittings a higher level of reliability.

In any LED Driver module, there are three basic components: the input capacitor, the main control element, and the output regulation circuit. The input capacitor limits the input current while the main control element, such as a transistor, switches the current on and off to control the LED. The output regulation circuit then ensures that the current remains constant by monitoring and adjusting the output current.

The ELG-200-C2100D2 LED Driver in particular is specifically designed for the purpose of powering a 3 Watt LED over a wide range of input voltages. It has two main features: first, it is very efficient, as it can draw up to 90% of the available input current. Second, it has a very low quiescent current, as low as 4μA, so it can be used in battery powered systems without draining the battery too quickly. Finally, it has an open-circuit protection system, which turns the output voltage off if no load is connected.

The working principle of the ELG-200-C2100D2 is quite simple. The input voltage is first rectified by a rectifier circuit, which then charges up an input capacitor. When the input voltage reaches a certain threshold, then the main switch, usually a transistor, is turned on, thus allowing the current flow to the LED. The main switch is then turned off and the output is regulated by a feedback loop. The feedback loop monitors the output voltage and adjusts the current accordingly to ensure a constant current output.

The primary application of the ELG-200-C2100D2 is for indoor and outdoor LED lighting, such as floodlights, pathway lights, downlights, and accent lights. It can also be used for back lighting, signage, accent lighting, emergency lighting, multimedia projections, and many other lighting applications. As its output is adjustable, it can be used for any number of LED configurations. It is also suitable for low power LED applications, such as measuring instruments and medical devices.

In conclusion, the ELG-200-C2100D2 LED Driver is a very versatile module that is well suited for a wide range of LED lighting applications. It is highly efficient, so it is perfect for battery powered systems, and its open-circuit protection system ensures that it will not be damaged by high or low input voltages. Its working principle is simple, and it ensures a constant current output for any number of LED configurations, making it perfect for a wide range of LED lighting applications.
