To build the perfect LED system, you need a range of different components working together to create the most energy efficient, visually pleasing project. Understanding and choosing the right components to create this experience can be complicated, given how unique each lighting environment is. One of the most critical aspects of this environment is the LED power supply - also known as a driver or transformer. Without the correct power supply, not only will the system not function properly, but you will not be able to adequately control your lighting system. How to decide which type of power supply is right for your LED system? It depends on many factors, from voltage requirements to dimming requirements and system environment, here are some key takeaways to achieve a quality solution for your LED system.

How does the power supply work?

Before we start deciding which power supply is right for you, let's take a quick overview of LED power supplies. Most LEDs are low voltage, which means they require a driver to convert AC to DC and keep the voltage flowing throughout the lighting process. Aside from this critical feature, the power supply ultimately determines how you control the LEDs. Maybe you want a wider range of dimming effects for your lighting project, maybe changing colors is a must for your signage outside your storefront. These factors help determine which LED power supply is better for your project.

Constant Voltage LED Driver

As the name suggests, constant voltage power supplies provide a fixed output voltage (usually 12V/24VDC) and maximum output current for optimal operation of the LED system. They are more flexible than constant current because more LEDs can be added to the system until the maximum current capability is reached, and any additional LEDs will just reduce the brightness. Constant voltage drivers are most commonly used for LED loads where the number of loads will vary, or when bright or contrasting colors are required.

Dimming

Another key factor in finding a power source is the dimming requirements of the LED system. Homeowners who require under-cabinet or task lighting are generally not interested in dimming, but if accent lighting or broad output is preferred, dimming capability will be more valued. 0-10V dimming, cutting-edge dimming technology, suitable for all 0-10V power supplies, smooth dimming without any technical limitations (no minimum power load required). Depending on your unique needs, there are a wide variety of power supplies available for your system, and Yansoda's 0-10V dimming driver is better for static color. Power integration is easier in a system, while also providing smooth dimming down to 1% without any flickering.
