Re: Voltage detectors?

Hi Dan

Wont the voltage sensor have to sit looking at the mains rather than
the UPS ?..From my understanding from what you said  the UPS is either fed
from mains or whens mains fail then generator ??? correct...if so then
probably could use a mains failure relay connected to the mains
