Due to the correlation between led light output and current it is possible to dim led lights if a controlled dimming 0 10v system is compatible with the led driver.
0 10v dimming led driver circuit.
For other types of dimming control systems consult controls manufacturer for wiring instructions.
A 0 10 dimmable led driver includes a power supply circuit that produces approximately 10vdc for the signal wires and sources an amount of current in order to maintain that voltage.
Wiring details class 2 preferred method.
Hot black typical 120v or 277v 60 hz neutral white ground ground.
Accordingly the driver is called the source.
These connect the dimming controller to one or more led drivers that have the correct input for 0 10 v dimming.
If class 1 is desired then actions should be taken to reduce the length of the 0 10v wires.
All you must do then is connect the dimming controller with the appropriate wires to the led driver.
0 10 v is one of the earliest and simplest electronic lighting control signaling systems.
Adding a 50k ohm resistor on a single driver led light would bring the light to 50.
0 volts represents its minimum level and depending on the driver the fixture will either go into sleep mode turn off completely or utilize a dimmer switch to turn off.
70k ohm would bring it to 70.
When they are touching the dimming control output will be 0 volts.
0 10v dimming can also be done as resistor dimming or pulse width modulation pmw.
Simply put the control signal is a dc voltage that varies between zero and ten volts.
0 10v dimming wiring diagram.
The dimming signal is usually connected to the lighting driver with a purple wire which carries the 10 volt charge and a grey wire which is the common wire carrying the signal.
In one method the controller dimmer sources current to the led driver.
When both wires are open the dimming control output will be 10 volts.
There are two methods of 0 10v dimming control.
Due to the characteristic of led and the design of certain drivers not all led drivers are compatible for usage with 0 10v dimmers therefore is it important to ensure your fixture has the appropriate technologies to facilitate your dimmer.

This is defined and supported by the esta e1 3 standard and is a preferred method in theatrical or entertainment technology applications.

These would require accurate resistors and stored in a well constructed box.
