I have a power supply (not a computer power supply, but rather a part from inside a larger piece of equipment) that produces an unknown voltage and frequency and I'm trying to figure what that output is.
It's possible that frequency and voltage may be as low as the standard 120v/60Hz or as high as in the thousands (at least one of the two would need to be increased a lot, and voltage is almost certainly increased). The total output is probably in the 20w-30w range. There seems to be some kind of serial number on it (9900103144), but it otherwise has no identifying marks.
What's the best way to find out the output of the power supply without buying expensive equipment? Is this something I can take down to a local electrical supply store and have measured?
