MULTI-MASTER 0-10V DIMMING CONTROLLER WITH REMASTERING CAPABILITY

摘要

A 0-10V dimming system includes at least two dimming controllers, at least one luminaire electrically connected to the dimming controllers, a control source connected to each of the dimming controllers, including a method to receive inputs about a dimming level, and a microcontroller coupled to each of the dimming controllers, the microcontroller configured to assert control of the dimming circuit over any other dimming controllers based upon the control source.

1. A 0-10V dimming system, comprising:
a first and a second dimming controller; at least one luminaire electrically connected to the dimming controllers; a control source input connected to each of the dimming controllers to provide a dimming level; and a first microcontroller coupled to the first dimming controller and a second microcontroller coupled to the second dimming controllers the microcontrollers configured to assert control of the dimming circuit over any other dimming controllers based upon the control source input via reducing, by the second controller, a voltage level on a bus below a first threshold and determining, by the first controller, that the voltage level on the bus has dropped below the first threshold.
