Transformer UPS vs. Transformerless UPS - Ward Boland
www.wardboland.comEmersonNetworkPower.com ENERGY EFFICIENCY comparisons Fact: Energy efficiency is a top-of-mind concern for data center managers and transformerless uPs designs can achieve higher efficiencies by replacing the uPs transformer with solid-state circuits. As the graph demonstrates, when comparing like-for-like operating parameters, the transformerless uPs achieves

www.eaton.commay be in a PDU (Power Distribution Unit). The LSIG in the feeder or service provides protection for the downstream equipment as there is no isolation transformer in a transformerless UPS. A downstream fault will pick up the LSIG in the feeder or service source, thus limiting the need for additional LSIG as fault protection on the UPS output.
