1-10 V is one of the earliest and simplest electronic lighting control signalling systems; simply put,
the control signal is a DC voltage that varies between zero and ten volts. The controlled lighting should scale its output so that at 10 V, the controlled light should be at 100% of its potential output, and at 0 V it should at 0% output (i.e. “Off”). Dimming devices may be designed to respond in various patterns to the intermediate voltages, giving output curves that are linear for: voltage output, actual light output, power output, or perceived light output.
There are two variations to the 0 to 10 V system, 0 to -10 V and 0 to +10 V. Despite being incompatible with each other, both systems were widely implemented by lighting manufacturers.[clarification needed]
Often, dimming ballasts and dimming LED power supplies use 0-10V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light completely off.
Most 0-10V controllers offer either a built-in line voltage relay or an external line voltage relay. Depending on the application, these options should be considered.
