LED drivers are devices that supply constant power to LED light sources and are typically used to replace traditional incandescent light bulbs. The RACD150-12 is a LED driver with many applications. This article discusses the features, application fields and working principle of the device.

Features

The RACD150-12 LED driver is a dimmable programmable LED driver with built-in open circuit, short circuit and over temperature protection. It is based on the RACD150 used in indoor LED lighting applications and has the following features:

• Input Voltage: 100-240V AC
• Output Voltage: 12V DC
• Maximum Output Power: 150W
• Output Regulation: 10.5V-13.23V
• Dimming Range: 0-100%
• Working Temperature: -20℃~60℃

The RACD150-12 LED driver has an efficiency of up to 91.6% and an overall no-load power consumption of 0.2 watts.

Application Fields

The RACD150-12 LED driver is suitable for various indoor applications such as office and commercial lighting, stage lighting, hotel lighting, and more. It is suitable for high-power LED light strips and is able to drive up to 10A current.

The RACD150-12 is also well-suited for most power LED lighting system applications, including street lights, wall washers, solar light systems, spotlights, architectural lighting, industrial lighting, and more.

Working Principle

The RACD150-12 LED driver converts alternating current (AC) into direct current (DC) with a rectifier circuit. The input voltage of the AC mains is rectified and filtered to provide a constant DC voltage. This DC voltage is then used to provide the base signal for most of the LED drivers’ components.

The LED driver monitors the output current and voltage to ensure that it is within a desirable range. It does this by measuring the current and voltage at the output and using a feedback loop to adjust the circuit parameters so as to maintain the desired output. This feedback loop also ensures that the driver is able to regulate the power output even when the input voltage varies.

The LED driver also includes dimming capability, which is achieved by using pulse width modulation (PWM) to adjust the output current. By varying the width of the pulses, the power output of the LED driver can be adjusted appropriately, resulting in dimmer or brighter light.

The RACD150-12 LED driver provides a reliable and efficient source of power for a wide variety of indoor LED lighting applications. It is well-suited for high-power lighting applications, is able to drive a wide range of current, and has built-in protection features and dimming capabilities.
