"RACD20-350/277” is an LED driver developed and launched by ACDI Electric, with its main application in LED lighting and lamp. This LED Driver is equipped with AC/DC input voltage adjustment capabilities, ranging from 347Vac/277Vac to 480Vac/277Vac. This article will focus on the LED drivers, the RACD20-350/277 application field and working principle.The RACD20-350/277 LED driver is widely used in architectural lighting, landscape lighting, decorative lighting, outdoor lighting, and other applications. It can support power range from 21W to 350W out of a 120V AC/DC input voltage. The maximum output current is 400mA. In addition, this LED driver supports multiple control systems, such as DALI, ON/OFF, DMX512, triac dimming, and 0-10V dimming, and is designed with an excellent surge protection of up to 3kV.The working principle of the RACD20-350/277 LED driver is rather straightforward. The input voltage first passes through the fire-resistant insulation material to ensure safety and then to a dedicated AC/DC rectifier bridge, which converts the AC voltage to DC voltage. Afterwards, the DC voltage is fed into a synchronous rectifier bridge to convert the DC voltage into a pulse width modulation (PWM) voltage, before it finally goes through an output bridge and a magnetic inductive element to the LED module in order to provide lighting.In terms of reliability, the RACD20-350/277 LED driver also has some unique advantages. Firstly, it is equipped with a reliable and efficient low harmonic passive PFC scheme to ensure that the power factor remains over 0.9 and the total current harmonic distortion does not exceed the standard 0.1 level. In addition, this driver also carries overload protection, over-voltage protection, over-current protection, and short circuit protection features to provide users with comprehensive and secure protection.In short, the RACD20-350/277 LED driver is equipped with many features and settings to meet the demands of lighting applications in both commercial and residential settings. Its AC/DC input voltage adjustment capabilities and high compatibility with several control systems and dimming controls make it suitable for a variety of lighting applications while its robust protection features ensure its safe operation and reliability in use.
