I want to trigger a relay so that when the input voltage is at 95 VAC (134 V peak), the relay is off. When the input voltage is at a full 120 VAC (170 V peak), or it goes beyond the 95 VAC threshold, then the relay is energized.
This circuit needs to be discrete enough to where I can put it on a small PC board inside of an enclosure. So I can't be using hulky 120 VAC relays or anything like that. The only source voltage is the input voltage that switches between 95 and 120 VAC. The relay will be switching on a seperate circuit that uses less than an amp of current (a series of LEDs). Thus, another reason why the relay doesn't have to be hulking.
I'm a newbie to this board, so I hope someone out there can help.
Thanks in advance!
