Direct Current Isolated-Parallel UPS Systems

This White Paper describes The Isolated-Parallel (“Iso-Parallel” or “IP”) configuration for rotary diesel UPS systems.

The Isolated-Parallel (“Iso-Parallel” or “IP”) configuration for rotary diesel UPS systems debuted in 2006. The first installations were in wholesale data centers where several customers shared a common facility. Operators of these facilities face the problem of “stranded capacity.” The power demands of one customer might grow beyond the capacity of their allotted UPS while another customer used only a portion of their UPS, and there was no way to let the overloaded customer share the extra capacity of the lightly loaded customer without each being exposed to the faults or maintenance activities of the other.
