UPC trouble!
I have a Tripp Lite BC-450 UPC, that works, but puts out 145 volts AC,
instead of the normal 120 vlots AC. I can't find any semiconductors shorted, or overheating, it just runs at too high an output. I'm using a fully charged acid 12 volt car battery as it's source! Input anyone? Dani. |

How are you measuring the voltage? Many meters will not give accurate RMS readings with the modified sine wave waveforms most of the UPS generate. David |
