LED Drivers are the power sources for LED lighting, providing current, driving and controlling power at the required voltage and providing the dynamic effects for solid-state lighting. EVM120W-3000-40 is one of the LED drivers, providing high performance, quality driving for LED lighting applications.

The EVM120W-3000-40 LED Driver is a Class 2 output power supply that is both slim and small in size, with an output power of 120W and a dimming range from 0-300W and 40V-90V. It is a single-output LED Driver, and it has an efficiency of 85%. Its thermal shutdown feature ensures that the system will not overheat, while its wide operating temperature range of -40℃ to +60℃ and waterproof design allows for use in different conditions, both indoors and outdoors.

The EVM120W-3000-40 LED Driver features a built-in overvoltage protection and a constant-current output. It has a power factor of more than 0.91, with a no-load power consumption of less than 0.4W. This LED Driver is rated for 17.5amps and certified for use in Europe and North America, making it suitable for both industrial and residential applications.

The working principle of the EVM120W-3000-40 LED Driver is based on a buck-boost converter. Buck-boost converters are used to convert a DC input voltage to a different DC output voltage, either lower or higher than the input. The buck-boost converter is essentially a transformer with a variable-speed switch that converts the DC input voltage to the required output voltage.

The EVM120W-3000-40 LED Driver uses a circuit with a voltage sensing resistor and opto-isolator, which detects the output voltage and adjusts the speed of the switch accordingly. When the output voltage is detected to be higher than the set voltage, the sensor sends a signal to the opto-isolator, which in turn activates the switch to reduce the speed. When the voltage is detected to be lower than the set voltage, the sensor sends a signal to the opto-isolator, which in turn activates the switch to increase the speed. The speed of the switch determines the output current, thus maintaining the output voltage.

In addition, the EVM120W-3000-40 LED Driver is equipped with a timer that provides intelligent dimming control and ensures that the efficiency of the system is optimized. It also features short circuit and overvoltage protection, which prevents the system from malfunctioning if there is a sudden change in the power supply or if the voltage is too high. Moreover, it has a wide input voltage range, from 110V to 277V, making it suitable for a variety of applications.

The EVM120W-3000-40 LED Driver is suitable for use in a range of LED applications, including LED strip lights, street lights, floodlights, spot lights, and decorative lights. It is also suitable for use in industrial and commercial lighting applications such as retail stores, restaurants, libraries, and office buildings. It provides a reliable source of power for LED lighting, and its slim and small size makes it easy to install in both indoor and outdoor locations.
