Circuit Requirements Questions (Design of a stadium lighting system) [Thread moved from a technical forum, so no Homework Template is shown] A controller is required to monitor the natural illumination of a sports stadium and, when the ambient light is below a pre-set level, to switch on ext...
Wire this Switch in place of a current wall switch according to the diagram above. When used, NWT00Z’s are required to be wired to the same line (or neutral) which is also wired to the master unit as well as the load being controlled, and not wired to any other neutral. If multip...
2) Not Connected (in a circuit diagram). NON DIMSChannels, usually controlled from the lighting desk, which are switched, rather than dimmed. This enables motors, slide projectors, smoke machines etc to be controlled from the lighting desk. Older dimmers can be setup so that the channels ...
Figure 2.Wiring Diagram for a commercial dimmer and power stage inside the dimmer. Image used courtesy ofBodo’s Power Systems Wiring Diagram The dimmer is a very simple black block with three terminals (plus ground) connected like the below schematic. It has a mechanical switch to turn on/o...

purely resistive loads that have unity power factor and will work with almost any dimmer or switch combination. Installing an LED is much more complicated. Besides a more sophisticated thermal management and appropriate photometric interface, an electronic LED ballast or driver is almost alwa...
1) To light the cyclorama or a piece of upstage set in such a way that the actors are cast into shadow. Can be a very dramatic effect. 2) (Trade Name) A range of 2000W lanterns manufactured by CCT in the UK. 3) The outline of a costume is called the silhouette.CCT Silhouette ...
The circuit diagram of the 20W LED driver is shown in Figure 9. This is a high PF design. This means that the output current in the secondary winding will have a high content of low frequency ripple, with a frequency which is double the line frequency. The main buffer element is output...
