0 10v Dimming Led Driver Circuit

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 the lowest possible dimming level.

0 10v dimming led driver circuit.

When both wires are open the dimming control output will be 10 volts. All you must do then is connect the dimming controller with the appropriate wires to the led driver. These connect the dimming controller to one or more led drivers that have the correct input for 0 10 v dimming. There are two methods of 0 10v dimming control.

The dimming performance of 0 10v can be impaired if the system is wired in a class 1 configuration especially if long distances of line voltage wiring are used. 0 10v dimming wiring diagram. If class 1 is desired then actions should be taken to reduce the length of the 0 10v wires. These would require accurate resistors and stored in a well constructed box.

70k ohm would bring it to 70. 0 10v dimmer switch leviton ip710 lfz or equal. Hot black typical 120v or 277v 60 hz neutral white ground ground. 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. When they are touching the dimming control output will be 0 volts. 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. For other types of dimming control systems consult controls manufacturer for wiring instructions.

Wiring details class 2 preferred method. Switched hot black switched hot red typical low voltage dimming wires purple gray typical electrical panel. In one method the controller dimmer sources current to the led driver. 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.

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. 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 the second method the controller dimmer sinks current from the led driver. This is defined and supported by the esta e1 3 standard and is a preferred method in theatrical or entertainment technology applications.

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.
