I gutted a piece of equipment from a financial institution and pulled this PS.
I've never seen one quite like this one.
110VAC in, says 28V out of the blue cap. (40,000uF, 40 VDC, Max surge - 50 VDC)
The gray cap says 3uF 660v. What is its purpose ?
How can I determine the MAX wattage of this unit ?
