208v to 120v Step-Down Auto Transfer Switch
Anybody have any luck finding or using a step-down Auto Transfer Switch that goes from 208v to 120v?
There are a few items on one of our racks that are 120v and I'd like to get them on redundant UPS' and this is the only way I can think of how to do it. All the UPS' in this room are 208v in and out.
Thanks

Are they WYE 208V 3PH? You could just pull a single phase and neutral for 120V, if thats the case. Be sure to balance the load.
If you need a single phase solution you will need a transformer. Preferably before a 120V UPS, but you could do it after a 208V UPS if needed. Just beware that the isolation and cleaning properties of the UPS could be affected by doing it this way. -

I used one of these for a client who had 208v, and colo wanted 500/mo to drop 120v feed for the 2-3 items that needed it.
