I realized now after I click post that I spelled Rectifier wrong in the Post title. Sorry.
So i cracked open a "power supply" for a theatrical communications system (Clearcom PK-7), It has a 30V DC power supply, It supplies power and audio connections to up to 30 beltpack/headset units. This particular piece of equipment is around $300. I need a second one, but the belt pack take a range of dc power from 8V to 13V or something like that.
I had thought to myself why couldn't I simply supply power to the units while connecting audio as well,obviously thats what this PK-7 unit is doing. So I opened it up to see. I am just starting out in getting my electronics education, so I thought I would ask around. Why would you need a rectifier after a DC power supply ? From the power supply pins the circuit heads straight for a W02G rectifier, now I had thought that the purpose of a rectifier was to change AC to DC. From the rectifier there are various connections to 3- 30V capacitors what looks like a voltage regulator, and a series of resistors and other components that look similar but I am unfamiliar with, probably to power the LED on the front.
Any insight, I could snap a photo if needed.
Also in case anyone cares, I did indeed hook a generic power supply i had to a set of XLR's and the packs totally function fine, so I am wondering what the need is for all this circuitry.
Thanks
In advance.
