Hi:

New poster here, just wondering if anyuone can help me with this beast.
I'm sort of hoping to use it as an isolation transformer for my
scanner. Overkill, I know, but it cost me all of 15 bucks. The
problem is the voltage it produces on the secondary is 132 volts with
line voltage in. The plate states secondary voltage is 118, so what's
causing the overage? Do I not have it loaded enough (rating, IIRC is
2.5 A) or could it be the capacitor failing? Any advice is
appreciated.

Thanks

Andrew

Have you checked the SOLA web site? Can you give us a model number?

@trndny04:

I'm curious how much the output
would be affected as the frequency drifted.

According to Sola's PDF for its CVS series of constant-voltage
transformers,
http://www.solaheviduty.com/products/powerconditioning/pdfs/opchars.pdf

you can expect the output voltage to rise about 1.5% for each 1% rise in
the frequency. So, freq goes up 1Hz, 1/60 = 1.7% x 1.5 = 2.5% x 120V =
3V rise.

This is true for their CVS series transformers---with other models, YMMV.
