Question about Computers & Internet
I am providing a very good web site (link provided)for you to look through. I have personally had a job or two troubleshooting a low voltage system for a customer. It is not easy and requires some good meter skills to say the least. The Selenium rectifier you mention is nothing more than a DC power supply for the low voltage relays the system uses. The whole premise of the low voltage control was the master control panel. This offered a home owner (in a large home) the ability to control all the lighting in the home from the master panel location. Now days, with all the new technology, companies like Lutron have RadioRa which does the same thing with radio frequency controlled switches throughout the home. Read the info I sent and you will get a clear picture of the old style 'low voltage system'.
