Re: Power Supply Voltage

[David Stanton]

quote Richard A. White:

Not being an electrician, I do not understand why if a power supply outputs 7.5 volts and appears regulated, how this might adversely effect the MercoTronic unit.

You are right Richard; as long as the max rated current is not exceeded by very much. All supplies, even regulated ones, start dropping below their rated voltage when you get above the maximum current they are rated at.

Now I have seen supplies that specify they are regulated over a given current range, like from 1 to 3 amps, and the voltage will vary outside the specified range, but these regulated supplies are rare today with switching-regulator technology.
