LED drivers are electronic devices used to power LED lighting. In general, LED drivers are designed to provide a precise voltage to drive a LED or LED array at its ideal operating current. Specific LED drivers may offer additional features such as dimming, strobing, and temperature management. The RCD-24-0.50/VREF is a high voltage LED driver with a wide range of applications and functions.

Overview

The RCD-24-0.50/VREF is a linear, compact, fast response high voltage LED driver. It is designed to be used in indoor and outdoor applications across a variety of industrial, commercial, and residential settings. The driver features an adjustable output voltage from 350 V to 850 V, making it suitable for use with both higher voltage and lower voltage LEDs. The driver also features a wide input range of 90-305 VAC, making it compatible with most mains power supplies. In addition, the driver is capable of delivering up to 24 W of power, making it suitable for large applications where multiple LEDs are used.

Application Field and Working Principle

The RCD-24-0.50/VREF is primarily designed for use in driving small strings of large LEDs. It is ideal for applications where large amounts of light are desired, but where the power budget is limited. It is suitable for indoor and outdoor lighting applications such as wall-mounted or ceiling-mounted fixtures, road and pathway lighting, amenity lighting, and public area lighting. The driver is also suitable for applications where the light output needs to be precisely controlled, such as in traffic signalization, security lighting, industrial process control, and medical treatments.

The RCD-24-0.50/VREF is based on the simplest LED driver topology, the linear constant current driver, which utilizes a single feedback loop to regulate the output current. The driver includes an AC/DC power supply, a regulator, a feedback loop, and a load switch. The AC/DC power supply converts the incoming mains voltage into a constant DC voltage. This DC voltage is then regulated down to the desired output voltage by the regulator. The feedback loop senses the output current by measuring the voltage across a small sense resistor, and compares it to a reference voltage. The output voltage is then adjusted until the output current matches the reference voltage. The load switch is used to turn the LED on and off.

Advantages

The RCD-24-0.50/VREF offers a range of benefits to users. It is highly efficient, featuring a power efficiency of up to 90%. This minimizes the amount of power it dissipates and improves the system’s thermal performance. The driver also offers a wide output operating range, allowing it to be used in different applications. The driver features a wide input range, making it compatible with most mains power supplies. The adjustable output voltage, from 350 V to 850 V, makes it suitable for use with both higher voltage and lower voltage LEDs. The driver is also capable of delivering up to 24 W of power, making it suitable for large applications. Finally, its wide temperature range, from -40°C to +70°C, makes it suitable for use in both cold and hot climates.

Conclusion

The RCD-24-0.50/VREF is a versatile, high voltage LED driver. It is suitable for a wide range of applications, from residential to industrial, and can be used in indoor and outdoor settings. Its adjustable output voltage, wide input range, and high power efficiency make it an ideal choice for applications where large amounts of light are required but the power budget is constrained. The driver’s wide operating temperature range also makes it suitable for use in both hot and cold climates.
