A Power Dimmer is a device that controls the brightness of lights in a room. It uses alternating current that flows in one direction and then back again along the cable. It is usually 50Hz or 60Hz depending on the country's power system. This type of electric current has two points of zero. The first is a stretched "S" shape, or the zero crossing point. This point is the moment that no current flows, and the second is the instant that it starts flowing again.
The third setting is the maximum amount of light that can be dimmed. The dimmer adjusts the amount of power that is delivered to the lighting load. As a result, it lowers the amount of light that is produced. Since the dimmer has a very high switching frequency, it is almost impossible to detect. The dimmer will operate at a preset level that is not higher than the light source's maximum output.
The third setting is to set a screen saver. This screen saver automatically dims the screen when you are not using it. The program is a free download for Windows XP and 2000. It is a useful tool for dimming lights, but it has some downsides. Some users may have difficulty installing it because it is not available in the windows store. The developer recommends that you download the latest version from the publisher.
