Variable output module and method for electrical signal output

摘要

A variable output module provides accurate full range dimming or adjustment of power output. The variable output module utilizes the characteristics of an AC or other periodic signal rather than its power output to accurately determine the level of dimming a user desires. In this manner, the variable output module provides accurate full range dimming without the need for calibration to specific AC signals. The variable output module can detect the period of an AC signal allowing the driver to be used with various frequencies without the need for calibration. In one or more embodiments, the driver compares the pulse widths of a dimmed AC signal to the period of the AC signal to determine the desired level of dimming.

1. A driver module for controlling electrical output comprising:
one or more input terminals configured to receive an electrical signal from an external device; a controller in electrical communication with the input, the controller configured to:
receive the electrical signal;determine a pulse width of the electrical signal;determine the period of the electrical signal; andgenerate a varying level of electrical output, wherein the electrical output is increased or decreased based on a ratio of the pulse width of the electrical signal to the period of the electrical signal; one or more output terminals configured to transmit the electrical output, wherein the electrical output represents a desired level of electrical power at the external device.
