0-10V and 1-10V are analog protocols used for dimming lighting. Both systems use voltage levels to communicate with the driver. There is an article about 0(1)-10V dimming drivers. In this article, we are discussing the difference between 0-10V and 1-10V.
Difference between 0-10V and 1-10V
1-10V is a current sink system. This means that the dimmer does not need mains power, the output status is unstable when the dimming signals less than 1V or even shorts the dimming wires. It could be completely switched off or there is still some light coming out of LED module. In order to prevent this situation happening, it would be required to completely turn off the driver. MOONS’ drivers support a ‘light off’ function without the need of switching mains power. Users can set minimal lighting level through programmable software—MSSL200. Fig1 is the configuration software interface.

0-10V is a current source system, which means that the dimmer provides the power for the 0-10V signals – a mains connection to the dimmer is necessary. MOONS’ 0-10V Drivers are programmable and dim down to 0.1% at a minimum light level.
When to use 0-10V or 1-10V?
0-10V and 1-10V systems are best suited for simple installations. In complex systems, installation can get complicated because each group needs its own wiring. 010V is mostly used for entertainment lighting while 110V is more common for general lighting.
