0 10v Dimming Ballast Wiring Diagram: Everything You Need to Know

When it comes to lighting systems, 0-10v dimming ballasts are the go-to solution for many commercial and industrial applications. These ballasts are designed to control the light output of fluorescent and LED lighting systems, allowing users to dim or brighten the lights as needed. But how do these ballasts work, and how do you wire them into your lighting system? In this article, we’ll take a closer look at 0-10v dimming ballast wiring diagrams and provide you with all the information you need to get started.

What is a 0-10v Dimming Ballast?

A 0-10v dimming ballast is a device that controls the light output of fluorescent and LED lighting systems. The “0-10v” refers to the voltage range that the ballast uses to control the light output. At 0 volts, the light output is at its lowest level, while at 10 volts, the light output is at its highest level. The ballast can adjust the voltage in between these two levels to dim or brighten the lights as needed.

0-10v dimming ballasts are commonly used in commercial and industrial applications where the lighting needs to be adjusted based on the time of day or the activity taking place in the space. For example, in a conference room, the lights may need to be dimmed during a presentation but brightened during a group discussion. With a 0-10v dimming ballast, these adjustments can be made quickly and easily.

How Does a 0-10v Dimming Ballast Work?

A 0-10v dimming ballast works by sending a signal to the lighting system that tells it how much voltage to use. The ballast itself is controlled by a separate device, such as a wall switch or a lighting control system. When the user adjusts the control device, the ballast sends a signal to the lighting system, which adjusts the voltage accordingly.

One of the benefits of 0-10v dimming ballasts is that they are compatible with both fluorescent and LED lighting systems. However, it’s important to note that not all lighting systems are compatible with 0-10v dimming ballasts. Before installing a 0-10v dimming ballast, you should check the compatibility of your lighting system to ensure that it will work properly.

0-10v Dimming Ballast Wiring Diagram

Now that you understand what a 0-10v dimming ballast is and how it works, let’s take a closer look at the wiring diagram. The wiring diagram will show you how to connect the ballast to the lighting system and the control device.

There are a few different components that you’ll need to wire together to create a functioning 0-10v dimming system. These components include:

  • The 0-10v dimming ballast
  • The lighting system (fluorescent or LED)
  • The control device (wall switch or lighting control system)
  • The power source

Here is a step-by-step guide to wiring a 0-10v dimming ballast:

  1. First, turn off the power to the lighting system by flipping the circuit breaker or turning off the power switch.
  2. Next, connect the power source to the input terminals on the ballast. The input terminals will be labeled “line” and “neutral.”
  3. Connect the lighting system to the output terminals on the ballast. The output terminals will be labeled “lamp” or “load.”
  4. Connect the control device to the control terminals on the ballast. The control terminals will be labeled “control” or “dim.”
  5. Finally, turn the power back on and test the system to ensure that it’s working properly.


0-10v dimming ballasts are a versatile and effective solution for controlling the light output of fluorescent and LED lighting systems. By using a 0-10v dimming ballast and a compatible control device, users can easily adjust the light output to meet their needs. If you’re considering installing a 0-10v dimming ballast in your lighting system, be sure to consult with a professional to ensure that the system is wired correctly and working properly.
