LED Drivers

LED drivers are an integral component of electric appliances or light fixtures, and are necessary for the proper functioning and reliability of a lighting system. They are used to regulate the delivery of current to the light source and are designed to protect both the led and power source from damage due to overcurrent or overvoltage.

The RACT18-1050 is a type of LED driver that is designed to guarantee a constant current to a connected LED or LEDs and is suitable for use in a wide range of applications. The output of the driver is adjustable through a connection using a programmable resistor.

Application Field

The RACT18-1050 LED driver is mainly used in a variety of lighting applications, such as providing LED light in commercials, residential and educational facilities, warehouses, outdoor applications, and many more. It is also commonly used in stages and studio lighting, and vehicles, as it has the ability to drive both single-channel LED or multi-channel LED circuits.

Apart from its use in lighting, the driver can also be used in other applications, such as for driving electronics, powering motors, and controlling audio and video equipment. The driver has a low heat generation due to its low quiescent current, and hence can be used in applications where power efficiency is of utmost importance. Additionally, it can be used to power low voltage systems, such as CCTV cameras.

Working Principle

The RACT18-1050 LED driver works on the principle of constant current regulation, where the voltage output is controlled by a programmable resistor placed in series with the LED. When connected to the DC input power source, the driver regulates the current-limiting resistor and the control circuitry to ensure that the output current is constant and provides optimal performance.

The internal circuitry of the driver has been designed to provide protection against overvoltage, overcurrent, and over-temperature conditions to ensure safe and efficient operation. The short-circuit protection feature ensures that the LED driver is protected from damage due to an abnormal current surge, while the open-circuit protection feature prevents damage to the power source if the LED circuit is open. The over-temperature protection feature helps in avoiding damage to the LEDs due to overheating.

The RACT18-1050 LED driver is designed to be used with a wide range of input voltages and provides a wide range of output current settings, making it a versatile and convenient choice for a variety of applications.
