Basic Knowledge of 0-10v

0–10 V is one of the first and simplest electronic lighting control signaling systems, used as an early fluorescent dimming system.[1] Simply put, the control signal is a DC voltage that varies between zero and ten volts. There are two recognized standards current sourcing, and current sinking.

Current Sinking[edit]

Typically utilized in architectural lighting, a current sinking control scheme uses ballast or driver provided 10 V DC. The controller reduces the returned volts to the light. If the controller returns the full 10 V, the light will be at its brightest level. The light will be at minimum level if no volts are returned. The current sinking scheme creates a fail safe situation. Should a control wire be cut or the controller fail, the lights will illuminate.

Commonly, the 10 V control voltage is supplied through a resistor. Control is achieved (and current is sunk) by connecting a variable resistor between the control voltage terminal and ground. The two resistors form a voltage divider to produce a control voltage Vc = Vs * (Rc / (Rc + Rs)) where Vc is the returned control voltage, Vs is the source voltage, Rc is the variable control resistance, and Rs is the source resistance. Vs may be greater than 10 V so that a maximum intended value of Rc produces a 10 V maximum control voltage. Rc must be adjusted to a value of 0 ohms (a direct short) to return a 0 V control voltage.

As a practical matter, many 0-10 V dimming control inputs can be operated by replacing the variable control resistor with an electronic switch. When the switch is on, the control voltage is near 0 and the light is fully dim. When the switch is off, the control voltage is maximum and the light is fully bright. The switch is controlled by a PWM (Pulse Width Modulation) signal, which alternately turns the switch on and off at a rapid rate. The relative proportion of off time vs. on time determines brightness. For example, if the switch is off 10% of the time, the resulting control signal would be the equivalent of 1 V produced with a variable resistor. The PWM method does not require selection of accurate resistance values. It can be applied simultaneously to control signals of multiple lights by connecting their control inputs in parallel.

As of the early 2020's, a significant percentage of –10 V dimmable LED flat panels do not respond rapidly to control signal changes or even follow the average control signal value. A pulse width modulated control signal, as described above, does not work well with such fixtures.

Dimming fluorescent ballasts and dimming LED drivers often use –10 V 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. Some 0–10 V controllers offer a built-in line voltage relay, others require an external line voltage relay. Some 0-10 V controllers, usually called 0-10 V Blink'n'Dim adapters, create a 0-10 V control signal in response to short blink signals from the power switch. Depending on the application, these options should be considered.
