So I have been running an EG8010 based inverter for awhile now, and recently connected a circuit which has a clock on it. The clock was running quite fast, so I compared the frequency of the inverter to the mains and found:
Mains: 59.98Hz
Inverter: 60.18Hz
This would suggest a crystal accuracy of 3000 PPM. Looking at the board, I can see the 2 capacitors connected to the crystal are present.
I would prefer to not take the system down till the weekend, so thought I would float this question.
What kind of frequency accuracy are you seeing with your EG8010 inverter?
Looking on Digikey, I see crystals in the correct package with 10ppm frequency accuracy and stability. The poorest frequency accuracy crystal I see, is 100ppm.
Thoughts?
