3.2 Power Supplies and Dimmers
{"Image DocumentName": "3.2 Power Supplies and Dimmers", "Image ImageDescription": "Most low voltage lighting systems are powered from the mains supply. As the mains supply voltage is 230V AC and we only require 24 or 12V, then we must reduce the mains voltage. This reduction is carried out in a device called a transformer which reduces the voltage using magnetic coupling. The diagram below shows how a transformer is connected into the lighting circuit.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
