Our company is in the final stages of having a new datacenter built and we just stumbled accross a problem. We have fans on the backs of our racks tht only take 120v power. Problem is that we spec'd the environment for only 208v power. We are thinking of getting a step down transformer but are having trouble finding something small enough. We've got about 80 racks that have door fans that need power that take only 120. We've got dual 208v PDUs in each rack. Any suggestions here?
