0 to 10 V is a simple analogue dimming standard commonly used in commercial lighting to provide smooth, flicker free dimming and straightforward compatibility with emergency and building management systems. The control uses a low voltage analogue signal to command the driver’s output level and is particularly popular in retrofit and industrial settings where a reliable, proven solution is required. Its strengths are simplicity and predictability, and because it is analogue it remains compatible with a wide range of drivers and fixtures.
