Dimming system powered by two current sources and having an operation indicator module
First Claim
1. A dimming system comprising:
- a first terminal configured to operatively connect to a first conductive line, wherein the first conductive line is configured to connect to a load;
a second terminal configured to operatively connect to a second conductive line, wherein the second conductive line is configured to supply an alternating current;
a third terminal configured to operatively connect to a third conductive line, wherein the third conductive line is configured to connect to a current path;
a controller operatively connected to at least one of the first, second and third terminals for controlling operation of the dimming system;
a primary power supply operatively connected to the first and second terminals; and
a secondary power supply operatively connected to the first and third terminals, wherein the secondary power source is a separate power supply from the primary power supply and is powered through at least one different connection than the primary power supply.

Abstract
A dimming system and method of operating the same are provided. The dimming system includes a first terminal configured to operatively connect to a first conductive line, a second terminal configured to operatively connect to a second conductive line, and a third terminal configured to operatively connect to a third conductive line. The first conductive line is configured to connect to a load, the second conductive line is configured to supply an alternating current, and the third conductive line is configured to connect to a current path. The dimming system further includes a controller operatively connected to at least one of the first, second and third terminals for controlling operation of the dimming system. The first and second terminals are configured for electrically connecting to a primary power supply and the first and third terminals are configured for electrically connecting to a secondary power supply. The primary power supply is powered through connection to neutral, and wherein the secondary power supply is powered through connection to an earth ground.
