VLB260W-48

LED Drivers are types of drivers used to power light-emitting diodes (LEDs). The VLB260W-48 is a type of LED driver designed to be versatile and easy to use.

The driver is a power-factor-corrected LED driver that provides constant current output and has been designed to be compatible with a wide array of switch-mode and linear power supplies. It uses a two-stage over-current protection (OCP) in order to ensure reliable operation. In addition, the driver has a low temperature coefficient, which helps it maintain consistent LED brightness as the ambient temperature changes. The VLB260W-48 has a current output range from 0.03A to 0.40A.

Application Field

The VLB260W-48 is designed for indoor or outdoor LED lighting applications such as street lights, area lighting, landscape lighting, tunnel lighting, billboard lighting, and office/architectural lighting. Its power factor correction feature makes it ideal for applications with limited space. In addition, it is designed for use with a wide variety of power supplies, making it an excellent choice for a variety of LED lighting applications.

Working Principle

The VLB260W-48 uses a switching power supply to convert alternating current (AC) power into direct current (DC) power. This DC power is then used to power the LED. The driver controls the current using a buck regulator, which adjusts the voltage to keep the LED supplied with the required amount of current. The driver also uses a two-stage over-current protection (OCP) to protect the LED from being damaged by too much current.

In order to ensure reliable operation, the VLB260W-48 features a thermal protection circuit which cuts off the output when the driver temperature exceeds a predetermined level. This prevents damage to the driver and also improves reliability. The driver also contains a control circuit which reduces flicker, providing a smooth, consistent LED light output over the entire dimming range.

The VLB260W-48 is a reliable and versatile LED driver that is designed for a wide variety of LED lighting applications. Its power factor correction feature makes it ideal for applications with limited space and its two-stage OCP ensure reliable operation. Additionally, its low temperature coefficient helps maintain consistent LED brightness even as ambient temperatures change.
