LED Drivers

The VLM40W-48 is a low-voltage, constant-current LED driver that is designed for simple, efficient, and reliable illumination control. It features a soft dimming and color regulation with very low power consumption. It can be used in residential, commercial, and hospitality lighting applications.

Features

The VLM40W-48 offers a wide range of features that make it a great choice for LED lighting applications. It features 0-10V dimming and RGB/RGBW color control, as well as adjustable power output from 10% to 100%. It is also compatible with remote control systems and can easily be placed in areas where installation is not feasible due to space limitations. In addition, the VLM40W-48 is UL, cUL, FCC and CE approved, and comes with a two-year warranty.The VLM40W-48 offers an adjustable range of power outputs, including 0-10 volts for dimming and RGB/RGBW color control, as well as 10% to 100% power output. This allows the user to easily adjust the brightness, color, and power output to suit any lighting application. Additionally, it has a wide operating temperature range of -20°C to +60°C, making it suitable for both indoor and outdoor installations. It is also IP67 rated, making it dust and waterproof.

Safety

The VLM40W-48 is designed with safety in mind. It features an integrated over-temperature protection that prevents the LED from over-heating. It also features short-circuit and overload protection to ensure the driver will not be damaged in the event of a power surge or other power related incident.

What is a Constant Current LED Driver?

A constant current LED driver is a device that regulates and allows LED lighting installations to function correctly. It regulates the output of the LED by providing it with a steady current, rather than fluctuating voltage, which would cause issues such as flickering or overheating. This in turn provides better illumination, more accurate colors, improved safety, and a longer lifespan for the LED.

Working Principle

The VLM40W-48 regulates the voltage that is supplied to each LED module. The driver uses a PWM (Pulse Width Modulation) based approach to regulate the input voltage and maintain a constant current output. This allows for exact output control of the LEDs, with a wide range of dimming and color control options. Additionally, the VLM40W-48 also features an externally adjustable adjustable OCP (Over Current Protection) setting, which helps to protect the LED modules from unintended over-current conditions.

Applications

The VLM40W-48 is suitable for a wide range of LED lighting applications, both indoor and outdoor. It is great for retail stores, hospitality, residential, and commercial lighting installations. It is very efficient, saving money on energy costs in the long run. Additionally, its adjustable power output and color control makes it a great choice for creating aesthetically pleasing environments.
