Three-phase to single-phase transformers, more commonly referred to as Three-to-Single-Phase transformers, convert three-phase signals into a single-phase 230 V signal. Sharing the same characteristics as isolating transformers, three-to-single-phase transformers are low voltage and separate the general distribution network from the supply of IT-powered medical premises. They therefore allow the isolation and partitioning of electrical disturbances in the entire installation.
