0-10V Dimming Multiple Fixtures Wiring Diagram
Introduction
0-10V dimming is a popular method for controlling lighting levels in various applications, including commercial and residential spaces. When it comes to dimming multiple fixtures, a proper wiring diagram is essential to ensure safe and reliable operation. In this article, we will provide a comprehensive guide on how to wire multiple fixtures for 0-10V dimming.
Understanding 0-10V Dimming
Before we dive into the wiring diagram, let's briefly explain how 0-10V dimming works. A 0-10V dimming system consists of a power supply, a dimmer controller, and one or more lighting fixtures. The dimmer controller produces a 0-10V DC output signal that is connected to the lighting fixtures. The voltage level of the output signal determines the brightness of the lights, with 0V representing off and 10V representing full brightness.
Wiring Diagram for Multiple Fixtures
Here is a sample wiring diagram for 0-10V dimming multiple fixtures:
Component List
- Dimmer controller (0-10V output)
- Power supply (12V or 24V DC)
- Multiple lighting fixtures (with 0-10V dimming capability)
- Dimming wires ( typically 2-conductor or 3-conductor)
Wiring Diagram
** Dimmer Controller **
- GND: Connect to power supply GND
- VDC: Connect to power supply VDC
- DIM: Connect to dimming wire (2-conductor or 3-conductor)
Power Supply
- GND: Connect to dimmer controller GND
- VDC: Connect to dimmer controller VDC
Lighting Fixture 1
- DIM: Connect to dimming wire (2-conductor or 3-conductor)
- VDC: Connect to power supply VDC
- GND: Connect to power supply GND
Lighting Fixture 2
- DIM: Connect to dimming wire (2-conductor or 3-conductor)
- VDC: Connect to power supply VDC
- GND: Connect to power supply GND
...and so on for each additional fixture
Wiring Notes
- Use a separate dimming wire for each lighting fixture to ensure independent control.
- Connect the dimming wire to the DIM terminal on the dimmer controller and the corresponding terminal on each lighting fixture.
- Connect the power supply VDC and GND terminals to the corresponding terminals on each lighting fixture.
- Make sure to observe proper wire sizing and voltage drop calculations to ensure reliable operation.
Conclusion
In this article, we have provided a comprehensive guide on how to wire multiple fixtures for 0-10V dimming. By following this wiring diagram and understanding the basics of 0-10V dimming, you can safely and reliably control multiple lighting fixtures in your application. Remember to always consult the manufacturer's instructions and local electrical codes for specific requirements and guidelines.
