LED Drivers: EVM120W-1400-84 Application Field and Working Principle

LED (Light Emitting Diode) drivers are essential components of any LED-based lighting system, as they supply and regulate the electricity to power LEDs. Roughly speaking, when the LED brightness is fixed and constant, the driver works as a direct current (DC) power source; when it is varied, the driver works as a regulator. The EVM120W-1400-84 is one of the most reliable and efficient LED drivers currently available, so today we will discuss its application field and working principle in detail.

Application Field

The EVM120W-1400-84 LED driver has a wide range of applications, from indoor lighting for homes, offices, and retail stores, to major industrial projects. This highly efficient driver has a power conversion rate of over 91 percent and can be easily integrated into lighting systems for both indoor and outdoor applications. It is especially suitable for use in places where the amount of light may need to be adjusted over time, such as in restaurants or theaters.Moreover, the EVM120W-1400-84 LED driver can efficiently and safely power LED lamps, downlights, high bay lights, strip lights, etc. It also meets the needs of both simple settings and more intricate scenarios such as dynamic effects, and can be used in any environment where reliable, dimmable, and adjustable lighting is required.

Working Principle

The EVM120W-1400-84 LED driver runs on a switching mode power supply (SMPS). This SMPS provides constant voltage and constant current to the LED load using the principle of Pulse Width Modulation (PWM). The PWM principle works by making the LED driver output high-frequency pulses of electricity at different widths according to the control signals received by the driver. The SMPS is monitored and adjusted by an intelligent Microcontroller Unit that measures the input current and drives the output of the LED driver. It establishes the voltage regulation without increasing the load, making the overall efficiency higher and the output current much more stable. The outputs of the LED driver can be adjusted in order to dim the light if needed. The EVM120W-1400-84 is designed for minimum power loss and built-in protections such as short circuit protection, over current protection and over voltage protection. This driver also has a dual hard-wired mode to ensure that the power would not turn off abruptly in the event of a fault. It is also equipped with a thermal protection function, so it can work effectively with long duration of use even in high-temperature environments. To sum up, the EVM120W-1400-84 LED driver is a highly efficient and reliable component that is suitable for a wide variety of LED lighting systems. Its high efficiency and wide range of protective features make it ideal for applications where adjustable brightness and stable output are required. The simple and reliable PWM principle operating the driver ensures a safe and efficient source of power for the LED load.
