PDU Transformers

Federal Pacific power distribution unit (PDU) transformers are specifically engineered for the critical power demands of modern data centers. We design specialized dry-type transformers to handle the high harmonic content generated by non-linear switching power supplies while maintaining maximum efficiency. Built with dual electrostatic shielding and high K-factor ratings, Federal Pacific PDU transformers provide the clean, reliable power isolation necessary to protect server racks, telecommunications hardware, and critical IT infrastructure from electrical noise and thermal stress.
