Today, a UPS with a dead battery was given to me..
A label underneath reads: The output of this device is not sinusoidal. It has a THD of 68% and max. harmonic of 57%.
Crazy Question: Can I make use of this UPS to create an isolated
120VAC or 170VDC source to safely test my homebrew offline smps with an earth grounded oscilloscope? The output power rating is ok. I'm assuming the UPS uses a lead-acid 12V batt.. I have a car battery. Arrfff Arrfff... :) To hack or not to hack?Maybe I can dodge ordering an isolation transformer from Digikey...(About $45.00CAD)
My local surplus electrical junk shop had a pile of transformers but no isolation types...strange...The owner looked too....nothing.
Too poor to get an isolated Tektronics TDS digital phosphor scope :( D from BC
