Anyone know of a 22mm or 30mm indicator that can be powered from either:

- 120VAC to 277VAC
or
- 208VAC to 480VAC

I'm working on a little relay monitor and the incoming AC voltage may be unknown.

Thank you,

Eric

These Eaton 22mm LEDs are almost there. Perhaps add a series resistor to move the range higher.

If this is for a new system rather than a replacement, then you cannot go above 120 vac per NFPA 79 handbook.

I don't have mine with me or I could tell you the location.
