That can extend the lifetime of any electric motor or other device using the conditioned power. The UPS emits a controlled waveform beyond what your utility can provide. And numerous datacenters have begun using DC-powered racks. Less power loss in the individual transformers and motors in each racked server, less heat to be expelled.
