1-10V VS DALI

HOW DOES DALI COMPARE WITH 1-10V?

DALI, like 1-10V, was designed for and by the lighting industry. Lighting control components, such as LED drivers and sensors, are available from a range of manufacturers that have DALI and 1-10V interfaces. However, that’s where the similarity ends.

The main differences between DALI and 1-10V are:

DALI is addressable. This opens the way for many valuable features such as grouping, scene-setting and dynamic control, such as changing which sensors and switches control which light fittings in response to office layout changes.

DALI is digital, not analogue. This means that DALI can offer much more precise light level control and more consistent dimming.

DALI is a standard, so, for example, the dimming curve is standardised meaning that equipment is interoperable between manufacturers. The 1-10V dimming curve has never been standardised, so using different brands of drivers on the same dimming channel could produce some very inconsistent results.

1-10V can only control switching on/off and simple dimming. DALI can manage colour control, colour changing, emergency lighting testing and feedback, complex scene-setting and many other lighting-specific functions.

1-10V (Analogue) Dimming uses an analogue signal rather than a digital signal. It is a universal protocol, so all 1-10V drivers operate in the same manner. Each downlight requires a standard 2C+E plus two control lines to carry the low voltage signal (polarity sensitive). You will also require a potentiometer (or some other 1-10V Dimming controller).

Additional 2-Core LV control cable is required.

Dedicated 1-10V interface or potentiometer is required to control this driver

Available in out-puts ranging from 350mA – 1400mA
