Control type: 0-10V
0-10V is an analog lighting control protocol. Basically, a 0-10V control applies a voltage
between 0 and 10 volts DC to produce a varying intensity level. There are actually
two existing 0-10V standards. They are not compatible with each other, so it is essential
to understand which type is required. The original 0-10V control was used for controlling
theatrical lighting. A lighting console provides a separate 0-10V output for each dimming
channel that connects to the input to dimmer modules located in a remote panel. The
other 0-10V control method was developed for, and is used as, a standard means for
controlling fluorescent dimming ballasts. It has now become popular for some drivers
used for LED lighting.

The standard requires that the ballast (or driver) provides full light output when the control
voltage is 10 Volts (or above). As the control voltage is reduced by the control, the light
level is reduced. At a control voltage of 1 volt, the ballast (driver) provides it’s minimum
light level. Any voltage less than 1 volt is defined as minimum. Some drivers' minimum
is off, while other drivers' minimum is the lowest light level of the driver. It is important to
understand what minimum is for a particular driver. For drivers that do not go to off at
minimum, a separate relay or switching device is required.

An additional specification that needs to be considered is the current carrying capacity of
the control. Standard 60929 Annex E requires the ballast (driver) to limit the current
draw to 2.0 mA maximum. This means that a control with a 50mA capacity can operate
25 ballasts (drivers) if they have a specified current of 2.0mA.
