LED Drivers - 7021-D-E-700 application field and working principle

LED Drivers, also known as LED power supplies, are electronic devices that take power from an external source and convert it into a current suitable for the direct current-powered LEDs. As LED lighting technology develops and grows more popular, LED drivers with various characteristics have become increasingly diverse and are sold in many different forms. For instance, the 7021-D-E-700 LED driver is one of the most popular, offering a range of voltage inputs, high efficiency, and a low form factor.

Application field

The 7021-D-E-700 LED driver is typically used to drive LED lighting, due to its easy to use and high reliability features. Examples of applications for this LED driver range from High Bay/Low Bay lighting to sensing "Smart City” applications in smart homes, offices, and industrial settings. Typical voltage inputs range from 90-277 VAC and feature PFC with a wide dimming range (CC/CV & 0~10V/PWM).

Working principle

The 7021-D-E-700 LED driver has a built-in current regulated and temperature compensated switch-mode power supply, with 85-95% efficiency across a wide range of input and output voltages. A power factor correction and harmonic treatment are also included in the device, to ensure that the efficiency is as high as possible and that the LED driver does not cause interference with other electronic devices. Additionally, thermal protection, short circuit protection and over voltage protection are all included in the LED driver in order to prevent any damage from unexpected events.

The LED driver is also equipped with a 0-10V DC dimming/PWM dimming range, allowing for easy and accurate dimming control of the LED lights. When used with different dimmers, the 7021-D-E-700 LED driver has a power efficiency of up to 92%. The LED driver has a short circuit and overcurrent protection, allowing it to quickly shut down in the event of an overcurrent or an open circuit.

Conclusion

The 7021-D-E-700 LED driver is one of the most versatile LED drivers on the market today, featuring a range of voltage inputs and a high efficiency rating. Its robust design and inclusion of various protections makes it an ideal choice for many different applications, such as High Bay/Low Bay lighting and smart home/office/industrial projects. With its range of dimming options, the 7021-D-E-700 is suitable for installations where precise dimming control is required.
