Hi all,
I'm wondering if anyone can tell me about how mains voltage varies within North America.
I recently shipped a few electronic gizmos, and one user on the west coast reported problems with the unit. After inspecting it, I found the cause to be excessive ripple in the power supply when being powered by insufficient voltages.
Here, I measure 122.5VAC out of the wall. As I've read, the nominal voltage is 120VAC with a variance of +/- 5%, which would be 114v - 126v. My circuit would definitely have problems with 114VAC. What do people do in this situation, design for 114V or even lower?
Mike
