Nortel Option 11C 208VAC Input Supply?

[BMANN06]

Afternoon All,

I have an older Nortel Option 11C (2 Chassis) system at our plant. Our UPS System batteries have failed, I have a suitable APC Smartups that I would like to use, however the output voltage on the APC Unit is 208V (no neutral). Currently the 2 chassis are each using one 120VAC Supply, it certainly appears that the PSU will accept the 208V I was hoping to get some clarification so i don't knock our system down and have to source PSU units for this system(s).

Can anybody help me out?

Thanks in advance this has been a great forum for me to learn how to program this PBX.

Brian
