Abstract
In an example embodiment, an improved lighting controller designed to reduce the effects of electromagnetic interference is introduced. The improved lighting controller contains various features to help ensure noise and signal isolation. First, a control board in the improved lighting controller is designed such that each of a plurality of circuits on the control board contain separate grounds, such that ground planes are isolated from one another rather than sharing a common ground. Additionally, a common mode filter is added to an alternating current input. Additionally, a high frequency filter circuit is also added to a digital input line to further reduce noise.
