Wanted to know if anyone has worked with one of these, if so where did you order your transformer from??? Are they noisy?
Thanks much,

I posted a question the other day about rectifying 90-125AC down to 48VDC. I ran into the problem I knew I would, voltage regulation over the voltage range.
After a little research I found ferroresonant transformers, they claim to hold output voltage within 3%.
I know that they heat up when...
I need to design a cheap and dirty power supply for a VERY LARGE BANK of LEDs. I mean very large.
Currently running 12 volts DC, looking to change our LED config around to 48 volt strings of LEDs. Need to take anywhere from 90 volts AC to 125 volts ac, rectify, smooth it and make it into a...
